Re: OpenMPI Fortran: 'Error reading module mpi' and unexpected but silent termination

If you need to add this option, then you're going to need to find

when dealing with g77 compiled libraries that can't be rebuilt
with gfortran. It is also possible that some odd non-default
options were set in CFLAGS, which may affect the ABI.

Steven,

Thanks for your kind answers, but more questions are popping up in my head:

1) Is there a standard way to find out what compiler flags were
used for creating the Open MPI Kubuntu package? Do you mean
something like this?

bartv@kortrijk:~$ mpif90 -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --enable-checking=release i486-linux-gnu
Thread model: posix
gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)


If this is what you mean, then I'm still puzzled what the exact mpif90 command
would be to try next...

2) What is an 'ABI'?


Regards,
Bart
