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.
which may be optionally overridden by version-specific rules.
For example the default rules for gcc on GNU/Linux x86_64 are in the
wmake/rules/linux64Gcc directory. If there is a need to change any of
the rules for a specific version of gcc, e.g. gcc-4.8.4 the directory
wmake/rules/linux64Gcc48 may be created into which any of the language
files may be provided containing the rules to override the defaults.
On 32bit OSs long is not unambiguously int32_t (or int64_t) causing
problems for IO operator resolution. This problem is avoided by
explicitly defining the following operators:
To compile with 64bit labels set
WM_LABEL_SIZE=64
in ~/OpenFOAM/dev/prefs.sh
source ~/.bashrc
then Allwmake in OpenFOAM-dev.
This will build into for example OpenFOAM-dev/platforms/linux64ClangDPInt64Opt
If WM_LABEL_SIZE is unset or set to 32:
WM_LABEL_SIZE=32
the build would be placed into OpenFOAM-dev/platforms/linux64ClangDPInt32Opt
Thus both 32bit and 64bit label builds can coexist without problem.
