[Coin-discuss] Compile BCP 1.0.0 with mpich

[Laszlo Ladanyi]

Hi Dan,

The "configure: error: Cannot find symbol MPI_Irecv with MPI" simply means
that the configure script couldn't link a simple executable that had a simgle
MPI_Irecv() call in its main function. You need to check the output of "mpicc
-link_info". Don't bother with the -D flags, mpi was compiled with autotools,
too, and Coin's configure should find the same definitions. But do look at
what libs does it return. Those are the libs you need to link against if you
are not using the mpicc/mpicxx script to compile and link C/C++ code, and
Coin's configure scripts do not use those scripts. My best guess is that you
need to link against at least the pthread lib as well as against mpich.
Supposing you get back:

elrond:~$ mpicc -link_info
cc -DUSE_STDARG -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_UNISTD_H=1
-DHAVE_STDARG_H=1 -DUSE_STDARG=1 -DMALLOC_RET_VOID=1
-L/usr/lib/mpich-shmem/lib -lmpich-shmem -lpthread -lrt

Then your configure command line would be:

../configure CXX=g++ CC=gcc --enable-static=yes
--with-mpi-incdir=/usr/lib/mpich-shmem/include
--with-mpi-lib="-L/usr/lib/mpich-shmem/lib -lmpich-shmem -lpthread -lrt"

Let me know if this works.

Thanks,
--Laci


If that doesn't work then check that
