The pre-processor macro 'OPENFOAM_PLUS' is defined with a numerical
value equal to the currently compatible version number.
This can be used judiciously within user coding to help with minor
differences between OpenFOAM versions. For example,
#ifdef OPENFOAM_PLUS
#if (OPENFOAM_PLUS >= 1612)
...
#endif
#endif
or simply
#if (OPENFOAM_PLUS >= 1612)
...
#endif
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.
- otherwise /lib/cpp may need a different library binding than
currently available and results in this type of error:
/usr/lib64/gcc/x86_64-suse-linux/4.4/cc1:
/data/app/OpenFOAM/ThirdParty-1.6.x/platforms/linux64/gcc-4.3.3/lib64/libstdc++.so.6:
version `GLIBCXX_3.4.11' not found (required by
/usr/lib64/libppl_c.so.2)
ENH: remove unused flex++ rule for SiCortex that was identical to the
general one anyhow.
