 ## OpenFOAM&reg; ThirdParty Environment Variables
 When using these scripts for building third-party libraries
 various environment variables are required or expected.
 ### Mandatory
 - **WM_THIRD_PARTY_DIR** : Location of third-party library sources etc
 - **WM_PROJECT_DIR** : The OpenFOAM project directory. <br>
  Used for `wmake` information, config files, etc
 - **WM_ARCH** : The target architecture (eg, Linux64)
 - **WM_OSTYPE** : The operating system type (eg, POSIX, MSwindows) <br>
  Used as fallback for determining the ending for dynamic libraries.
  Used for Windows-specific handling in scotch builds.
 - **WM_COMPILER** : The compiler name (eg, Gcc, Clang)
 - **WM_COMPILER_LIB_ARCH** : The target library ending (eg, 64). <br>
  Typically used as `lib$WM_COMPILER_LIB_ARCH` to generate the name
  `lib64`, for example.
 - **WM_LABEL_SIZE** : The OpenFOAM size for `label` (eg, 32 for int32)
 - **WM_PRECISION_OPTION** : The OpenFOAM representation for `scalar`
  (eg, DP for double-precision)
 - **FOAM_EXT_LIBBIN** : Common _pool_ for the library targets.
 ### MPI-related
 - **FOAM_MPI** : The OpenFOAM MPI sub-directory name (eg, sys-openmpi)
 - **WM_MPLIB** : The canonical OpenFOAM MPI name (eg, SYSTEMOPENMPI)
 - **MPI_ARCH_PATH** : Location of the current MPI implementation.
  Used for additional linkage, but primarily to set MPI_ROOT
  for a cmake hint.
 ### Other
 - **WM_CONTINUE_ON_ERROR** : Ignore build errors.
  Mostly set internally from `wmake -k`.
 - **WM_NCOMPPROCS** : The number of build processes to launch.
  Often set internally from `wmake -j`.
 - **WM_COMPILER_TYPE** : Used internally for a few build scripts.
  Has values of `system` or `ThirdParty`.
 ## Output
 Similar to OpenFOAM itself, the build and final output are separated
 into different directories that contain a non-colliding hierarchy of
 target names. However, in contrast to the OpenFOAM target names,
 there are several different types of output targets:
 - *ARCH* : (eg, `linux64`) <br>
  Base infrastructure such as compiler and base libraries.
 - *ARCH+COMPILER* : (eg, `linux64Gcc`) <br>
  Compiler-specific libraries and applications.
 - *ARCH+COMPILER+SIZING* : (eg, `linux64GccDPInt32`) <br>
  Libraries and applications specific to a particular combination
  of OpenFOAM scalar/label sizes. This is the same as the
  ***WM_OPTIONS*** value.
 By default, the locations of the build and final targets are hard-coded
 relative to the WM_THIRD_PARTY_DIR:
 - WM_THIRD_PARTY_DIR<b>/build/</b> : intermediate build artifacts
 - WM_THIRD_PARTY_DIR<b>/platforms/</b> : installation root
 The expert user or sys-admin can influence these locations with the
 following environment variables
 - **FOAM_THIRD_PARTY_BUILDROOT** :
  Replaces WM_THIRD_PARTY_DIR as the root for build/ and platforms/.<br>
  ***!! The specified build-root directory must exist !!***
 - **FOAM_THIRD_PARTY_SOURCES** :
  Provide alternative location to WM_THIRD_PARTY_DIR/sources
  for finding source bundles.<br>

 # Description
 #     Extract package names from SOURCES.md and resolve their respective
 #     (unpacked) directory paths.
 #
 #     The input source file is assumed to be Markdown formatted with
 #     sections for each OpenFOAM version, followed by a '-' bulleted
 #     list of the software package/versions.
 #
 # Example,
 #     # OpenFOAM-2106
 #
 #     - ADIOS2-2.6.0
 #     - CGAL-4.12.2

Mark Olesen	1054dd83cf	CONFIG: adjust boost toolset for intel compiler (#62 ) - improve handling of different gcc/clang versions - support -toolset=none to bypass all internal logic and let boost do everything.	2021-12-09 17:39:20 +01:00
Mark Olesen	0d0f439dde	ENH: reproducible build naming for openmpi - configure with the arch + package only for the prefix. When OPAL_PREFIX is unset, yields this type of information: Prefix: /linux64Gcc/openmpi-4.0.3 Libdir: /linux64Gcc/openmpi-4.0.3/lib This ensures that the final binaries do not have the original build location, which makes for more reliable testing before shipping. ENH: improve handling of header-only CGAL - test for existence now also checks our cached build information for header-only configuration - cleanup build artifacts from boost (in-source build). Skip install of generated man, info, doc pages. These are usually browsed/searched elsewhere anyhow.	2021-12-09 16:30:28 +01:00
Mark Olesen	325e3e230d	ENH: improve flexibility of make scripts - the various make scripts now also search hierarchical sources, which makes it easier to organize sources. The secondary sub-directory is the lower-case value of the package stripped of trailing non-alphabet characters. For example, searching for ParaView-v5.9.1 sources/ \|-- adios \| \|-- ... \| \|-- ADIOS2-2.7.1 \| \-- adios-1.13.1 \|-- cgal \| \|-- CGAL-4.12.2 \| \-- CGAL-4.14.2 \| ... \|-- openmpi \| \|-- openmpi-4.0.3 \| \-- openmpi-4.1.1 \|-- paraview \| \|-- ParaView-v5.6.1 \| \-- ParaView-v5.9.1 \-- scotch ... - additional out-of-source build options FOAM_THIRD_PARTY_BUILDROOT : Replace WM_THIRD_PARTY_DIR as the root for build/ and platforms/ FOAM_THIRD_PARTY_SOURCES : Alternative to WM_THIRD_PARTY_DIR/sources/ - rationalise internal package variable names for easier maintenance	2021-12-09 16:30:28 +01:00
Mark Olesen	f1fe6c9866	ENH: explictly set scotch INTSIZE. Tag scotch libs with -intNN ending - Use WM_LABEL_SIZE to explicitly define INTSIZE32 or INTSIZE64, which ensures that SCOTCH_Num appears as (int32_t \| int64_t) and avoids any ambiguity that a plain 'int' may have. - Provide library symlinks to the respective label-size. Eg, libscotch.so -> libscotch-int32.so This provides a unique library linkage name that avoids ambiguity with system-installed libraries. - Use IDXSIZE64 (memory addressing width Fortran) NOTE Unfortunately -DINT32 seems to fail if openmpi was built without Fortran! The MPI_INT32_T is interpreted as MPI_INTEGER4 which does not exist - needs more investigation ENH: scotch - document Makefile.inc by copying into the source directory ENH: update kahip build to use cmake for newer versions	2021-12-09 16:30:28 +01:00
Mark Olesen	1f6835794f	ENH: add etc/tools support for hierarchically named sources	2021-12-09 16:30:28 +01:00
Mark Olesen	665437cf8c	ENH: support explicit int-32/64 for metis, scotch - simplifies creation of 64bit indexed libraries, for reuse (with widening) by various OpenFOAM label sizes - add -bin/-no-bin for metis (as per scotch)	2021-09-02 10:38:07 +02:00
Mark Olesen	cd853a6270	DOC: update requirements and version information	2021-06-07 13:12:30 +02:00
Mark Olesen	2beb3cfbc9	CONFIG: respect existing value for WM_NUMCOMPPROCS (#59 ) - avoids flooding a head-node during compilation.	2021-03-23 11:38:44 +01:00
Mark Olesen	c8542bd70d	CONFIG: update MESA build script for meson - also add LLVM_ARCH_PATH/bin into PATH (for finding llvm-config)	2021-03-23 11:38:13 +01:00
Mark Olesen	f84990e906	CONFIG: avoid deprecated CMake variables (ParaView) - use MPI_ARCH_PATH to provide an MPI hint when making ParaView, VTK and ADIOS. This should align the detected MPI with what OpenFOAM itself is using. Option -mpi-home to override.	2021-02-16 14:26:51 +01:00
