cpp is no longer used to pre-process Make/files files allowing standard make '#'
syntax for comments, 'ifdef', 'ifndef' conditionals etc. This is make possible
by automatically pre-pending SOURCE += to each of the source file names in
Make/files.
The list of source files compile can be specified either as a simple list of
files in Make/files e.g.
# Note: fileMonitor assumes inotify by default. Compile with -DFOAM_USE_STAT
# to use stat (=timestamps) instead of inotify
fileMonitor.C
ifdef SunOS64
dummyPrintStack.C
else
printStack.C
endif
LIB = $(FOAM_LIBBIN)/libOSspecific
or
or directly as the SOURCE entry which is used in the Makefile:
SOURCE = \
adjointOutletPressure/adjointOutletPressureFvPatchScalarField.C \
adjointOutletVelocity/adjointOutletVelocityFvPatchVectorField.C \
adjointShapeOptimizationFoam.C
EXE = $(FOAM_APPBIN)/adjointShapeOptimizationFoam
In either form make syntax for comments and conditionals is supported.
so that it can be included directly into the wmake Makefile to allow full
support of gmake syntax, variables, functions etc.
The Make/files file handled in the same manner as the Make/options file if it
contains the SOURCE entry otherwise it is first processed by cpp for backward
compatibility.
The list of source files compile can now be specified either as a simple list of
files in Make/files e.g.
adjointOutletPressure/adjointOutletPressureFvPatchScalarField.C
adjointOutletVelocity/adjointOutletVelocityFvPatchVectorField.C
adjointShapeOptimizationFoam.C
EXE = $(FOAM_APPBIN)/adjointShapeOptimizationFoam
or directly as the SOURCE entry which is used in the Makefile:
SOURCE = \
adjointOutletPressure/adjointOutletPressureFvPatchScalarField.C \
adjointOutletVelocity/adjointOutletVelocityFvPatchVectorField.C \
adjointShapeOptimizationFoam.C
EXE = $(FOAM_APPBIN)/adjointShapeOptimizationFoam
In both cases the Make/files is first parsed by cpp to handle #if, #ifdef
etc. directives but in the latter form gmake directives like ifeq can be also be
used to optionally select files to compile, typically using
SOURCE += anotherFile.C
statements.
gcc version 5 and above and clang version 3.4 and above fully support the C++14
standard and the compilation rules of OpenFOAM-dev now require this support
allowing for further development and maintenance to benefit from the additional
language features provided in C++14.
Now lnInclude are created as required by the presence of entries in the EXE_INC
variable in the Make/options file. This removes the need for calling
wmakeLnInclude in various Allwmake files to ensure the existence of the
lnInclude directories prior to compilation of dependent libraries.
This change ensures only one include file is open at a time by storing the
included files on a dynamic list rather than scanning the tree and holding a
list of open buffers. This new approach is a bit faster and avoids the "too
many open files" error on machines with low limits on the number of file
descriptors allocated to users.
to avoid the need for sed'ing the output. This improves performance by avoiding
the need for calling additional commands and generating a temporary file.
