[Trilinos-Users] linking problems

[James Willenbring]

Wilbert,

Try adding -lmpichcxx to your --with-mpi-libs value, to the right or the
left of -lmpich, which ever is appropriate.  Also, are the libraries in the
/home/wilbert/Libraries/MPICH/mpich2-1.0.7/linux_gfortran directory, or is
this the base of your mpich installation?  

You could also try brute force with

--ldflags="-L/path/to/mpi-libs -lmpichcxx -lmpich"

(or put -lmpichcxx to the right of -lmpich, if appropriate)

Subject: [Trilinos-Users] linking problems

Hi,

I'm having a hopefully trivial problem, which nonetheless has been
bugging me for days now:

In the configure phase of the package ml, the linker 'ld' isn't able to
find the library -lmpichcxx. This is despite the fact that I directly
point to the directory with the --with-mpi directive. I even have the
environmental variable LD_LIBRARY_PATH set to point to this directory.

When I don't include the ml package, configure and make go well, but now
'make tests' gives me trouble: again the linker 'ld' cannot find the
library -lmpich (when making tests of sacado).

Any suggestions are greatly appreciated!

Thanks,

-Wilbert.



My configure script:

../configure --
prefix=/home/wilbert/Libraries/TRILINOS/trilinos-9.0.0/linuxgfortran_mpi
\
--with-blas=/home/wilbert/Libraries/LAPACK/lapack-3.1.1/blas_gfortran.a
