LAMMPS and LAMMPS GUI universal binaries for macOS (arm64/x86_64)
=================================================================
This package provides universal binaries of LAMMPS and LAMMPS GUI that should
run on macOS systems running running macOS version 11 (Big Sur) or newer. Note
the binaries are compiled without MPI support and contain a compatible subset
of the available packages.
The following individual commands are included:
binary2txt lammps-gui lmp msi2lmp phana stl_bin2txt
After copying the lammps-gui folder into your Applications folder, please follow
these steps:
1. Open the Terminal app
2. Type the following command and press ENTER:
open ~/.zprofile
This will open a text editor for modifying the .zprofile file in your home
directory.
3. Add the following lines to the end of the file, save it, and close the editor
LAMMPS_INSTALL_DIR=/Applications/LAMMPS.app/Contents
LAMMPS_POTENTIALS=${LAMMPS_INSTALL_DIR}/share/lammps/potentials
LAMMPS_BENCH_DIR=${LAMMPS_INSTALL_DIR}/share/lammps/bench
MSI2LMP_LIBRARY=${LAMMPS_INSTALL_DIR}/share/lammps/frc_files
PATH=${LAMMPS_INSTALL_DIR}/bin:$PATH
export LAMMPS_POTENTIALS LAMMPS_BENCH_DIR PATH
4. In your existing terminal, type the following command make the settings active
source ~/.zprofile
Note, you don't have to type this in new terminals, since they will apply
the changes from .zprofile automatically.
Note: the above assumes you use the default shell (zsh) that comes with
MacOS. If you customized MacOS to use a different shell, you'll need to modify
that shell's init file (.cshrc, .bashrc, etc.) instead with appropiate commands
to modify the same environment variables.
5. Try running LAMMPS (which might fail, see step 7)
lmp -in ${LAMMPS_BENCH_DIR}/in.lj
6. Try running the LAMMPS GUI
lammps-gui ${LAMMPS_BENCH_DIR}/in.rhodo
Depending on the size and resolution of your screen, the fonts may
be too small to read. This can be adjusted by setting the environment
variable QT_FONT_DPI. The default value would be 72, so to increase
the fonts by a third one can add to the .zprofile file the line
export QT_FONT_DPI=96
and reload as shown above.
7. Give permission to execute the commands (lmp, lammps-gui, msi2lmp, binary2txt, phana, stl_bin2txt)
MacOS will likely block the initial run of the executables, since they
were downloaded from the internet and are missing a known signature from an
identified developer. Go to "Settings" and search for "Security settings". It
should display a message that an executable like "lmp" was blocked. Press
"Open anyway", which might prompt you for your admin credentials. Afterwards
"lmp" and the other executables should work as expected.

^^^^^^^^^^^^^^^^^^^^^^^^^
CMake is an alternative to compiling LAMMPS in the traditional way
through :doc:`(manually customized) makefiles <Build_make>` and a recent
addition to LAMMPS thanks to the efforts of Christoph Junghans (LANL)
and Richard Berger (Temple U). Using CMake has multiple advantages that

- CMake can detect available hardware, tools, features, and libraries
and adapt the LAMMPS default build configuration accordingly.
- CMake can generate files for different build tools and integrated
development environments (IDE).
- CMake supports customization of settings with a command line, text
mode, or graphical user interface. No knowledge of file formats or
complex command line syntax is required.

CMake can detect which version of the CUDA toolkit is used and thus will try
to include support for **all** major GPU architectures supported by this toolkit.
Thus the GPU_ARCH setting is merely an optimization, to have code for
the preferred GPU architecture directly included rather than having to wait
for the JIT compiler of the CUDA driver to translate it.

than having to wait for the JIT compiler of the CUDA driver to translate

setting :code:`CUDA_ENABLE_MULTIARCH` to :code:`no`.
When compiling for CUDA or HIP with CUDA, version 8.0 or later of the CUDA toolkit
is required and a GPU architecture of Kepler or later, which must *also* be
supported by the CUDA toolkit in use **and** the CUDA driver in use.
When compiling for OpenCL, OpenCL version 1.2 or later is required and the
GPU must be supported by the GPU driver and OpenCL runtime bundled with the driver.

If you are compiling for OpenCL, the default setting is to download, build, and
link with a static OpenCL ICD loader library and standard OpenCL headers. This
way no local OpenCL development headers or library needs to be present and only
OpenCL compatible drivers need to be installed to use OpenCL. If this is not

If you are compiling with HIP, note that before running CMake you will have to
set appropriate environment variables. Some variables such as
:code:`HCC_AMDGPU_TARGET` (for ROCm <= 4.0) or :code:`CUDA_PATH` are necessary for :code:`hipcc`
and the linker to work correctly.

Using CHIP-SPV implementation of HIP is now supported. It allows one to run HIP
code on Intel GPUs via the OpenCL or Level Zero backends. To use CHIP-SPV, you must
set :code:`-DHIP_USE_DEVICE_SORT=OFF` in your CMake command line as CHIP-SPV does not
yet support hipCUB. The use of HIP for Intel GPUs is still experimental so you
should only use this option in preparations to run on Aurora system at ANL.

.. _mscg:
MSCG package
-----------------------
To build with this package, you must download and build the MS-CG
library. Building the MS-CG library requires that the GSL
(GNU Scientific Library) headers and libraries are installed on your
machine. See the ``lib/mscg/README`` and ``MSCG/Install`` files for
more details.
.. tabs::
.. tab:: CMake build
.. code-block:: bash

-D MSCG_LIBRARY=path # MSCG library file (only needed if a custom location)
-D MSCG_INCLUDE_DIR=path # MSCG include directory (only needed if a custom location)
If ``DOWNLOAD_MSCG`` is set, the MSCG library will be downloaded
and built inside the CMake build directory. If the MSCG library
is already on your system (in a location CMake cannot find it),
``MSCG_LIBRARY`` is the filename (plus path) of the MSCG library
file, not the directory the library file is in.
``MSCG_INCLUDE_DIR`` is the directory the MSCG include file is in.
.. tab:: Traditional make
You can download and build the MS-CG library manually if you
prefer; follow the instructions in ``lib/mscg/README``\ . You can
also do it in one step from the ``lammps/src`` dir, using a
command like these, which simply invokes the
``lib/mscg/Install.py`` script with the specified args:
.. code-block:: bash
make lib-mscg # print help message
make lib-mscg args="-b -m serial" # download and build in lib/mscg/MSCG-release-master
# with the settings compatible with "make serial"
make lib-mscg args="-b -m mpi" # download and build in lib/mscg/MSCG-release-master
# with the settings compatible with "make mpi"
make lib-mscg args="-p /usr/local/mscg-release" # use the existing MS-CG installation in /usr/local/mscg-release
Note that 2 symbolic (soft) links, ``includelink`` and ``liblink``,
will be created in ``lib/mscg`` to point to the MS-CG
``src/installation`` dir. When LAMMPS is built in src it will use
these links. You should not need to edit the
``lib/mscg/Makefile.lammps`` file.

Exception handling when using LAMMPS as a library
------------------------------------------------------------------
-------------------------------------------------
This setting is useful when external codes drive LAMMPS as a library.
With this option enabled, LAMMPS errors do not kill the calling code.
Instead, the call stack is unwound and control returns to the caller,
e.g. to Python. Of course, the calling code has to be set up to
*catch* exceptions thrown from within LAMMPS.

LAMMPS errors do not kill the calling code, but throw an exception. In
the C-library interface, the call stack is unwound and control returns
to the caller, e.g. to Python or a code that is coupled to LAMMPS and
the error status can be queried. When using C++ directly, the calling
code has to be set up to *catch* exceptions thrown from within LAMMPS.

output, depending on the data requested through *what*. Note that *index*
uses 1-based indexing to access thermo output columns.

Note that this function actually does not return a value, but rather
associates the pointer on the left side of the assignment to point to
internal LAMMPS data (with the exception of string data, which are
copied and returned as ordinary Fortran strings). Pointers must be
of the correct data type to point to said data (typically
``INTEGER(c_int)``, ``INTEGER(c_int64_t)``, or ``REAL(c_double)``).
The pointer being associated with LAMMPS data is type-checked at
run-time via an overloaded assignment operator. The pointers
returned by this function point to temporary, read-only data that may
be overwritten at any time, so their target values need to be copied
to local storage if they are supposed to persist.

The latter has to be :ref:`enabled at compile time <exceptions>`.
This function checks if exceptions were enabled.
When using the library interface with C++ exceptions enabled, the library
interface functions will "catch" them, and the error status can then be
checked by calling :f:func:`has_error`. The most recent error message can be
retrieved via :f:func:`get_last_error_message`.
This can allow one to restart a calculation or delete and recreate
the LAMMPS instance when a C++ exception occurs. One application
of using exceptions this way is the :ref:`lammps_shell`. If C++
exceptions are disabled and an error happens during a call to
LAMMPS or the Fortran API, the application will terminate.

Using the LAMMPS GUI
====================
LAMMPS GUI is a simple graphical text editor that is linked to the
:ref:`LAMMPS C-library interface <lammps_c_api>` and thus can run LAMMPS
directly using the contents of the editor's text buffer as input.
This is similar to what people traditionally would do to run LAMMPS:
using a regular text editor to edit the input and run the necessary
commands, possibly including the text editor, too, from a command line
terminal window. That is quite effective when running LAMMPS on
high-performance computing facilities and when you are very proficient
in using the command line. The main benefit of a GUI application is
that this integrates well with graphical desktop environments and many
basic tasks can be done directly from within the GUI without switching
to a text console or requiring external programs or scripts to extract
data from the generated output. This makes it easier for beginners to
get started running simple LAMMPS simulations and thus very suitable for
tutorials on LAMMPS. But also makes it easier to switch to a full
featured text editor and more sophisticated visualization and analysis
tools.
-----
The following text provides a detailed tour of the features and
functionality of the LAMMPS GUI. This document describes LAMMPS GUI
version 1.2.
Main window
-----------
When LAMMPS GUI starts, it will show the main window with either an
empty buffer, or have a file loaded. In the latter case it may look like
the following:
.. image:: JPG/lammps-gui-main.png
:align: center
:scale: 50%
There is the menu bar at the top, then the main editor buffer with the
input file contents in the center with line numbers on the left and the
input colored according to the LAMMPS input file syntax. At the bottom
is the status bar, which shows the status of LAMMPS execution on the
left ("Ready." when idle) and the current working directory on the
right. The size of the main window will be stored when exiting and
restored when starting again. The name of the current file in the
buffer is shown in the window title and the text `*modified*` is added
in case the buffer has modifications that are not yet saved to a file.
Opening Files
^^^^^^^^^^^^^
The LAMMPS GUI application will try to open the first command line
argument as input file, further arguments are ignored. When no
argument is given LAMMPS GUI will start with an empty buffer.
Files can also be opened via the ``File`` menu or by drag-and-drop
of a file from a file manager to the editor window. Only one
file can be open at a time, so opening a new file with a filled
buffer will close this buffer and in case the buffer has unsaved
modifications will ask to either cancel the load, discard the
changes or save them.
Running LAMMPS
^^^^^^^^^^^^^^
From within the LAMMPS GUI main window LAMMPS can be started either from
the ``Run`` menu or by the hotkey `Ctrl-Enter` (`Command-Enter` on
macOS). LAMMPS is running in a separate thread, so the GUI will stay
responsive and thus is capable to interact with the calculation and
access its data. It is important to note, that LAMMPS is using the
contents of the input buffer for the run, **not** the file it was read
from. If there are unsaved changes in the buffer, they *will* be used.
.. image:: JPG/lammps-gui-running.png
:align: center
:scale: 75%
While LAMMPS is running, the contents of the status bar change: on the
left side there is a text indicating that LAMMPS is running, which will
contain the selected number of threads, if thread-parallel acceleration
was selected in the ``Preferences`` dialog. On the right side, a
progress bar is shown that displays the estimated progress on the
current :doc:`run command <run>`. Additionally, two windows will open:
the log window with the captured screen output and the chart window
with a line graph created from the thermodynamic output of the run.
The run can be stopped cleanly by using either the ``Stop LAMMPS`` entry
in the ``Run`` menu or with the hotkey `Ctrl-/` (`Command-/` on macOS).
This will cause that the running LAMMPS process will complete the
current iteration and then stop. This is equivalent to the command
`timer timeout 0 <timer>` and implemented by calling the
:cpp:func:`lammps_force_timeout()` function of the LAMMPS C-library
interface.
Viewing Snapshot Images
^^^^^^^^^^^^^^^^^^^^^^^
By selecting the ``View Image`` entry in the ``Run`` menu or by hitting
the `Ctrl-I` (`Command-I` on macOS) hotkey, LAMMPS gui will issue a
:doc:`write_dump image <dump_image>` command and read the resulting
snapshot image into an image viewer window.
.. image:: JPG/lammps-gui-image.png
:align: center
:scale: 50%
The image size, some default image quality settings, and some colors
can be changed in the ``Preferences`` dialog window. From the image
viewer window further adjustments can be made: high-quality rendering,
anti-aliasing, display of box or axes, zoom factor. The the image can
be rotated horizontally and vertically and it is possible to only
display the atoms within a predefined group (default is "all").
After each change, the image is rendered again and the display updated.
Editor Functions
^^^^^^^^^^^^^^^^
The editor has the usual functionality that similar programs have: text
selection via mouse or with cursor moves while holding the Shift key,
Cut, Copy, Paste, Undo, Redo. All of these editing functions are available
via hotkeys. When trying to exit the editor with a modified buffer, a
dialog will pop up asking whether to cancel the quit, or don't save or
save the buffer's contents to a file.
Context Specific Help
^^^^^^^^^^^^^^^^^^^^^
.. image:: JPG/lammps-gui-popup-help.png
:align: center
:scale: 50%
A unique feature of the LAMMPS GUI is the option to look up the
documentation for the command in the current line. This can be achieved
by either clicking the right mouse button or by using the `Ctrl-?`
hotkey. When clicking the mouse there are additional entries in the
context menu that will open the corresponding documentation page in the
online LAMMPS documentation. When using the hotkey, the first of those
entries will be chosen directly.
Menu
----
The menu bar the entries ``File``, ``Edit``, ``Run``, ``View``, and ``About``.
Instead of using the mouse to click on them, the individual menus can also
be activated by hitting the `Alt` key together with the corresponding underlined
letter, that is `Alt-f` will activate the ``File`` menu. For the corresponding
activated sub-menus, also the underlined letter, together with the `Alt` key can
be used to select instead of the mouse.
File
^^^^
The ``File`` menu offers the usual options:
- ``New`` will clear the current buffer and reset the file name to ``*unknown*``
- ``Open`` will open a dialog to select a new file
- ``Save`` will save the current file; if the file name is ``*unknown*``
a dialog will open to select a new file name
- ``Save As`` will open a dialog to select and new file name and save
the buffer to it
- ``Quit`` will exit LAMMPS GUI. If there are unsaved changes, a dialog
will appear to either cancel the quit, save or don't save the file.
In addition, up to 5 recent file names will be listed after the ``Open``
entry that allows to re-open recent files. This list is stored when
quitting and recovered when starting again.
Edit
^^^^
The ``Edit`` menu offers the usual editor functions like ``Undo``,
``Redo``, ``Cut``, ``Copy``, ``Paste``, but also offers to open the
``Preferences`` dialog and to delete all stored preferences so they
will be reset to their defaults.
Run
^^^
The ``Run`` menu allows to start and stop a LAMMPS process. Rather than
calling the LAMMPS executable as a separate executable, the LAMMPS GUI
is linked to the LAMMPS library and thus can run LAMMPS internally
through the :ref:`LAMMPS C-library interface <lammps_c_api>`.
Specifically, a LAMMPS instance will be created by calling
:cpp:func:`lammps_open_no_mpi` and then the buffer contents run by
calling :cpp:func:`lammps_commands_string`. Certain commands and
features are only available, after a LAMMPS instance is created. Its
presence is indicated by a small LAMMPS ``L`` logo in the status bar at
the bottom left of the main window.
The LAMMPS calculation will be run in a concurrent thread so that the
GUI will stay responsive and will be updated during the run. This can
be used to tell the running LAMMPS instance to stop at the next
timestep. The ``Stop LAMMPS`` entry will do this by calling
:cpp:func:`lammps_force_timeout`, which is equivalent to a :doc:`timer
timeout 0 <timer>` command.
The ``Set Variables`` entry will open a dialog box where :doc:`index style variables <variable>`
can be set. Those variables will be passed to the LAMMPS instance when
it is created and are thus set *before* a run is started.
.. image:: JPG/lammps-gui-variables.png
:align: center
:scale: 75%
The ``Set Variables`` dialog will be pre-populated with entries that are
set as index variables in the input and any variables that are used but
not defined as far as the built-in parser can detect them. New rows for
additional variables can be added through the ``Add Row`` button and
existing rows deleted by clicking on the ``X`` icons on the right.
The ``View Image`` entry will send a :doc:`dump image <dump_image>`
command to the LAMMPS instance, read the resulting file, and show it in
an ``Image Viewer`` window.
The ``View in OVITO`` entry will launch `OVITO <https://ovito.org>`_
with a :doc:`data file <write_data>` of the current state of the system.
This option is only available, if the LAMMPS GUI can find the OVITO
executable in the system path.
The ``View in VMD`` entry will instead launch VMD, also to load a
:doc:`data file <write_data>` of the current state of the system. This
option is only available, if the LAMMPS GUI can find the VMD executable
in the system path.
View
^^^^
The ``View`` menu offers to show or hide the three optional windows
with log output, graphs, or images. The default settings for those
can be changed in the ``Preferences dialog``.
About
^^^^^
The ``About`` menu finally offers a couple of dialog windows and an
option to launch the LAMMPS online documentation in a web browser. The
``About LAMMPS GUI`` entry displays a dialog with a summary of the
configuration settings of the LAMMPS library in use and the version
number of LAMMPS GUI itself. The ``Quick Help`` displays a dialog with
a minimal description of LAMMPS GUI. And ``LAMMPS Manual`` will open
the main page of this LAMMPS documentation at https://docs.lammps.org/.
Preferences
-----------
The ``Preferences`` dialog allows to customize some of the behavior
and looks of the LAMMPS GUI application. The settings are grouped
and each group is displayed within a tab.

General Settings:
^^^^^^^^^^^^^^^^^
- *Echo input to log:* when checked, all input commands, including
variable expansions, will be echoed to the log window. This is
equivalent to using `-echo screen` at the command line. There is no
log *file* produced since it always uses `-log none`.
- *Include citation details:* when checked full citation info will be
included to the log window. This is equivalent to using `-cite
screen` on the command line.
- *Show log window by default:* when checked, the screen output of a
LAMMPS run will be collected in a log window during the run
- *Show chart window by default:* when checked, the thermodynamic
output of a LAMMPS run will be collected and displayed in a chart
window as line graphs.
- *Replace log window on new run:* when checked, an existing log
window will be replaced on a new LAMMPS run, otherwise each run will
create a new log window.
- *Replace chart window on new run:* when checked, an existing chart
window will be replaced on a new LAMMPS run, otherwise each run will
create a new chart window.
- *Replace image window on new render:* when checked, an existing
chart window will be replaced when a new snapshot image is requested,
otherwise each command will create a new image window.
- *Select Default Font:* Opens a font selection dialog where the type
and size for the default font (used for everthing but the editor and
log) of the application can be set.
- *Select Text Font:* Opens a font selection dialog where the type and
size for the text editor and log font of the application can be set.
Accelerators:
^^^^^^^^^^^^^
This tab enables to select accelerator settings and is equivalent to
using the `-suffix` and `-package` flags on the command line. Only
settings supported by the LAMMPS library and local hardware are
available. The `Number of threads` field allows to set the maximum
number of threads for the accelerator packages that use threads.
Snapshot Image:
^^^^^^^^^^^^^^^
This tab allows to set some defaults for the snapshot images displayed
in the ``Image Viewer`` window, like its dimensions and the zoom factor
applied. The *Antialias* switch requests to render images with twice
the number of pixels for width and height and then uses a bi-cubic
scaling algorithm to rescale them back to the requested size. This
produces higher quality images with smoother edges at the expense of
requiring more CPU time to render the image. The *HQ Image mode* option
turns on using a screen space ambient occlusion mode (SSAO) when
rendering images. This is also more time consuming, but produces a more
'spatial' representation of the system. Finally there are a couple of
drop down lists to select the background and box color.
Hotkeys
-------
Almost all functionality is accessible from the menu or via hotkeys.
The following hotkeys are available (On macOS use the Command key
instead of Ctrl/Control).

These are: `mpi.h`, `cstddef`, `cstdio`, `cstdlib`, `string`,

also means any such file can assume that `FILE`, `NULL`, and

If the member variable is relevant to the functionality of a class
(for example when it stores a value from a command line argument), the
member variable declaration is followed by a brief comment explaining
its purpose and what its values can be. Class members that are
pointers should always be initialized to ``nullptr`` in the
initializer list of the constructor. This reduces clutter in the
header and avoids accessing uninitialized pointers, which leads to
hard to debug issues, class members are often implicitly initialized
to ``NULL`` on the first use (but *not* after a :doc:`clear command

LAMMPS GUI
----------
.. versionadded:: 2Aug2023
Overview
^^^^^^^^
LAMMPS GUI is a simple graphical text editor that is linked to the
:ref:`LAMMPS C-library interface <lammps_c_api>` and thus can run LAMMPS
directly using the contents of the editor's text buffer as input.
This is similar to what people traditionally would do to run LAMMPS:
using a regular text editor to edit the input and run the necessary
commands, possibly including the text editor, too, from a command line
terminal window. This similarity is a design goal. While making it easy
for beginners to start with LAMMPS, it is also the intention to simplify
the transition to workflows like most experienced LAMMPS users do.
All features have been extensively exposed to hotkeys, so that there is
also appeal for experienced LAMMPS users, too, especially for
prototyping and testing simulations setups.
Features
^^^^^^^^
A detailed discussion and explanation of all features and functionality
are in the :doc:`Howto_lammps_gui` tutorial Howto page.
Here are a few highlights of LAMMPS GUI
- Text editor with syntax highlighting customized for LAMMPS
- Text editor will switch working directory to folder of file in buffer
- Text editor will remember up to 5 recent files
- Context specific LAMMPS command help via online documentation
- LAMMPS is running in a concurrent thread, so the GUI remains responsive
- Support for accelerator packages
- Progress bar indicates that LAMMPS is running
- LAMMPS can be started and stopped with a hotkey
- Screen output is captured in a Log Window
- Thermodynamic output is captured and displayed as line graph in a Chart Window
- Visualization of current state in Image Viewer (via :doc:`dump image <dump_image>`)
- Many adjustable settings and preferences that are persistent
- Dialog to set variables from the LAMMPS command line
Parallelization
^^^^^^^^^^^^^^^
Due to its nature as a graphical application, it is not possible to use
the LAMMPS GUI in parallel with MPI, but OpenMP multi-threading and GPU
acceleration is available and enabled by default.
Prerequisites and portability
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
LAMMPS GUI is programmed in C++ based on the C++11 standard and using
the `Qt GUI framework <https://www.qt.io/product/framework>`_.
Currently, Qt version 5.12 or later is required; Qt 5.15LTS is
recommended; Qt 6.x not (yet) supported. Building LAMMPS with CMake is
required. The LAMMPS GUI has been successfully compiled and tested on:
- Ubuntu Linux 20.04LTS x86_64 using GCC 9, Qt version 5.12
- Fedora Linux 38 x86\_64 using GCC 13 and Clang 16, Qt version 5.15LTS
- Apple macOS 12 (Monterey) and macOS 13 (Ventura) with Xcode on arm64 and x86\_64, Qt version 5.15LTS
- Windows 10 and 11 x86_64 with Visual Studio 2022 and Visual C++ 14.36, Qt version 5.15LTS
- Windows 10 and 11 x86_64 with MinGW / GCC 10.0 cross-compiler on Fedora 38, Qt version 5.15LTS
Pre-compiled executables
^^^^^^^^^^^^^^^^^^^^^^^^
Pre-compiled LAMMPS executables including the GUI are currently
available from https://download.lammps.org/static or
https://github.com/lammps/lammps/releases. You can unpack the archives
(or mount the macOS disk image) and run the GUI directly in place. The
folder may also be moved around and added to the ``PATH`` environment
variable so the executables will be found automatically. The LAMMPS GUI
executable is called ``lammps-gui`` and either takes no arguments or
attempts to load the first argument as LAMMPS input file.
Compilation
^^^^^^^^^^^
The source for the LAMMPS GUI is included with the LAMMPS source code
distribution in the folder ``tools/lammps-gui`` and thus it can be can
be built as part of a regular LAMMPS compilation. :doc:`Using CMake
<Howto_cmake>` is required. To enable its compilation, the CMake
variable ``-D BUILD_LAMMPS_GUI=on`` must be set when creating the CMake
configuration. All other settings (compiler, flags, compile type) for
LAMMPS GUI are then inherited from the regular LAMMPS build. If the Qt
library is packaged for Linux distributions, then its location is
typically auto-detected since the required CMake configuration files are
stored in a location where CMake can find them without additional help.
Otherwise, the location of the Qt library installation must be indicated
by setting ``-D Qt5_DIR=/path/to/qt5/lib/cmake/Qt5``, which is a path to
a folder inside the Qt installation that contains the file
``Qt5Config.cmake``.
It should be possible to build the LAMMPS GUI as a standalone
compilation (e.g. when LAMMPS has been compiled with traditional make),
then the CMake configuration needs to be told where to find the LAMMPS
headers and the LAMMPS library, via ``-D
LAMMPS_SOURCE_DIR=/path/to/lammps/src``. CMake will try to guess a
build folder with the LAMMPS library from that path, but it can also be
set with ``-D LAMMPS_LIB_DIR=/path/to/lammps/lib``.
Rather than linking to the LAMMPS library during compilation, it is also
possible to compile the GUI with a plugin loader library that will load
the LAMMPS library dynamically at runtime during the start of the GUI
from a shared library; e.g. ``liblammps.so`` or ``liblammps.dylib`` or
``liblammps.dll`` (depending on the operating system). This has the
advantage that the LAMMPS library can be updated LAMMPS without having
to recompile the GUI. The ABI of the LAMMPS C-library interface is very
stable and generally backward compatible. This feature is enabled by
setting ``-D LAMMPS_GUI_USE_PLUGIN=on`` and then ``-D
LAMMPS_PLUGINLIB_DIR=/path/to/lammps/plugin/loader``. Typically, this
would be the ``examples/COUPLE/plugin`` folder of the LAMMPS
distribution.
Platform notes
^^^^^^^^^^^^^^
macOS
"""""
When building on macOS, the build procedure will try to manufacture a
drag-n-drop installer, LAMMPS-macOS-multiarch.dmg, when using the 'dmg'
target (i.e. ``cmake --build <build dir> --target dmg`` or ``make dmg``.
To build multi-arch executables that will run on both, arm64 and x86_64
architectures natively, it is necessary to set the CMake variable ``-D
CMAKE_OSX_ARCHITECTURES=arm64;x86_64``. To achieve wide compatibility
with different macOS versions, you can also set ``-D
CMAKE_OSX_DEPLOYMENT_TARGET=11.0`` which will set compatibility to macOS
11 (Big Sur) and later, even if you are compiling on a more recent macOS
version.
Windows
"""""""
On Windows either native compilation from within Visual Studio 2022 with
Visual C++ is supported and tested, or compilation with the MinGW / GCC
cross-compiler environment on Fedora Linux.
**Visual Studio**
Using CMake and Ninja as build system are required. Qt needs to be
installed, tested was a binary package downloaded from
https://www.qt.io, which installs into the ``C:\\Qt`` folder by default.
There is a custom `x64-GUI-MSVC` build configuration provided in the
``CMakeSettings.json`` file that Visual Studio uses to store different
compilation settings for project. Choosing this configuration will
activate building the `lammps-gui.exe` executable in addition to LAMMPS
through importing package selection from the ``windows.cmake`` preset
file and enabling building the LAMMPS GUI and disabling building with MPI.
When requesting an installation from the `Build` menu in Visual Studio,
it will create a compressed ``LAMMPS-Win10-amd64.zip`` zip file with the
executables and required dependent .dll files. This zip file can be
uncompressed and ``lammps-gui.exe`` run directly from there. The
uncompressed folder can be added to the ``PATH`` environment and LAMMPS
and LAMMPS GUI can be launched from anywhere from the command line.
**MinGW64 Cross-compiler**
The standard CMake build procedure can be applied and the
``mingw-cross.cmake`` preset used. By using ``mingw64-cmake`` the CMake
command will automatically include a suitable CMake toolset file (the
regular cmake command can be used after that). After building the
libraries and executables, you can build the target 'zip'
(i.e. ``cmake --build <build dir> --target zip`` or ``make zip``
to stage all installed files into a LAMMPS_GUI folder and then
run a script to copy all required dependencies, some other files,
and create a zip file from it.
Linux
"""""
Version 5.12 or later of the Qt library is required. Those are provided
by, e.g., Ubuntu 20.04LTS. Thus older Linux distributions are not
likely to be supported, while more recent ones will work, even for
pre-compiled executables (see above). After compiling with
``cmake --build <build folder>``, use ``cmake --build <build
folder> --target tgz`` or ``make tgz`` to build a
``LAMMPS-Linux-amd64.tar.gz`` file with the executables and their
support libraries.
