[cgma-dev] build issues, libtool

[Jed Brown]

The libtool issue also applies to MOAB, but 'ln -sf /usr/bin/libtool
libtool' in the build directory works for me.  In addition, though MOAB
supports --with-imesh=nofortran, this leaks since CGM does not have this
capability, hence FC_FUNC_ is defined when iGeom.h is included and thus
pollutes iMesh.h (iRel.h includes them in this order).  Can you
namespace the FC_FUNC_ macro to be MOAB_FC_FUNC_ and CGM_FC_FUNC_?

The libtool issue also applies to Lasso.  In the Lasso build, I need to
use C++ and mpicxx because MOAB is built in parallel.

/bin/sh ./libtool --tag=CC   --mode=link gcc  -fPIC   -o rtestc rtestc.o libiRel.la /home/jed/usr/lib/libiGeom.la /home/jed/usr/lib/libiMesh.la

The build succeeds when I use --tag=CXX and s/gcc/mpicxx/.


My last remaining problem is with MOAB, I now need to use a C++ linker
(mpicxx) when linking with libiMesh (despite calling from pure C where I
would like to link with mpicc) due to

/home/jed/usr/lib/libiMesh.so: undefined reference to `ompi_mpi_cxx_op_intercept'
/home/jed/usr/lib/libiMesh.so: undefined reference to `MPI::Datatype::Free()'
/home/jed/usr/lib/libiMesh.so: undefined reference to `MPI::Comm::Comm()'
/home/jed/usr/lib/libiMesh.so: undefined reference to `MPI::Win::Free()'


Thanks,

Jed
