- CGAL itself includes its library dependencies, we only need to
provide the -L... option to the proper ThirdParty locations.
Should help improve general build robustness.
The change from C++0x to C++11 allows all of C++11 functionality to be
used in OpenFOAM, in particular constructor delegation which avoids code
duplication or constructor helper functions. However, this also means a
change to the minimum gcc version supported which is now 4.7 rather than
4.5.
Note that gcc-4.7 does not support the entire C++11 standard but does
support all of the functionality currently needed for further OpenFOAM
development. The minimum gcc-version which supports the entire C++11
standard is 4.8 which is now the recommended minimum gcc version.
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
- return 0 if not under git, since nothing particular can be said
about the build number.
- explicitly define which git-dir is to be used.
This ensure we don't accidentally get some values from some unrelated
project in the parent directory.
and added support for queue scheduling option '-q', '-queue'
Now the 'Allwmake' scripts execute 'wmake -all' to handle parallel
processing in a general way, avoiding code duplication.
wmakeCollect collects the compilation commands for the all of the object
files to be compiled into a single makefile which is passed to make to
schedule the compilations in parallel efficiently.
Before wmakeCollect can be called the lnInclude directories must be
up-to-date and after wmakeCollect the linkage stage of the compilation
must executed using wmake.
This entire process is now handled by wmake using the new '-queue' or
'-q' option to compile sections of the OpenFOAM source tree or the
entire tree efficiently. The number of cores the compilation executes
on may be specified either using the WM_NCOMPPROCS variable or the '-j'
option.
To efficiently compile OpenFOAM after a 'git pull' the '-update' option
is provided which updates lnInclude directories, dep files and removes
deprecated files and directories. This option may be used with '-q':
wmake -q -update
