Hello,
I compile libmesh0.62 in Ubuntu 8.04, when "make examples", there is a
problem shown as follow:
ex0.i686-pc-linux-gnu.opt.o: In function `MPI::Op::Init(void (*)(void
const*, void*, int, MPI::Datatype const&), bool)':
/usr/lib/openmpi/include/openmpi/ompi/mpi/cxx/op_inln.h:122: undefined
reference to `ompi_mpi_cxx_op_intercept'
ex0.i686-pc-linux-gnu.opt.o: In function `Intracomm':
/usr/lib/openmpi/include/openmpi/ompi/mpi/cxx/intracomm_inln.h:23:
undefined reference to `MPI::Comm::Comm()'
ex0.i686-pc-linux-gnu.opt.o: In function `Intracomm':

ex0.i686-pc-linux-gnu.opt.o:(.data.rel.ro._ZTVN3MPI3WinE[vtable for
MPI::Win]+0x24): undefined reference to `MPI::Win::Free()'
collect2: ld return 1
make[1]: *** [ex0-opt] return 1
make[1]: Leaving directory `/home/cfd/Library/libmesh/examples/ex0'
make: *** [examples] return1
The mpi library used by PETSc have be changed to openmpi, I change the
compiler using
/configure --with-cxx=mpicxx --with-cc=mpicc --with-f77=mpif77, but it not OK !
Thank you!
