Dear all,
I'm trying to install gromacs 4.5.3, I've succesfully installed fftw
3.3.2 and openmpi 1.4.3
When I try to configure gromacs with
./configure --with-fft=fftw3 --enable-shared --enable-mpi
the shell reply me with this error:
configure: error: cannot compute sizeof (off_t)
See `config.log' for more details.
what does it mean? Do you need a copy of config.log?
This kind of problem usually means that configure has failed to find a
compiler that can produce an executable under the conditions you're
using. You need a compiler available that can link to openmpi, and
perhaps to tell configure about it (e.g. ./configure <blah>
MPICC=mympicompiler)
