- if FOAM_EXT_LIBBIN is unset and some scripts set this to /usr/lib*
as a fallback (eg, to avoid an undefined value) this will cause a
system library to be found before appropriate *_ARCH_PATH entry.
This was noticed during a scotch compilation without third-party:
resulting in the system library (/usr/lib64/libscotch.so) to be found
instead of the SCOTCH_ARCH_PATH location
(/usr/lib64/mpi/gcc/openmpi/lib64/).
Simply changing the search order doesn't work for use, since we wish
to retain a preference for any dynamic libraries discovered in a
real FOAM_EXT_LIBBIN.
Circumvent these issues by only taking libraries from
FOAM_EXT_LIBBIN if it also points to a location within ThirdParty.
- generalize some of the library extensions (.so vs .dylib).
Provide as wmake 'sysFunctions'
- added note about unsupported/incomplete system support
- centralize detection of ThirdParty packages into wmake/ subdirectory
by providing a series of scripts in the spirit of GNU autoconfig.
For example,
have_boost, have_readline, have_scotch, ...
Each of the `have_<package>` scripts will generally provide the
following type of functions:
have_<package> # detection
no_<package> # reset
echo_<package> # echoing
and the following type of variables:
HAVE_<package> # unset or 'true'
<package>_ARCH_PATH # root for <package>
<package>_INC_DIR # include directory for <package>
<package>_LIB_DIR # library directory for <package>
This simplifies the calling scripts:
if have_metis
then
wmake metisDecomp
fi
As well as reducing clutter in the corresponding Make/options:
EXE_INC = \
-I$(METIS_INC_DIR) \
-I../decompositionMethods/lnInclude
LIB_LIBS = \
-L$(METIS_LIB_DIR) -lmetis
Any additional modifications (platform-specific or for an external build
system) can now be made centrally.
