Re: [Starpu-devel] Cannot find MPI

The -x test is definitely not the first one.

So, you should check the execute permission of the MPICC compiler. It's all the configure script does.

I attach a patch which gives a better error message.

Hello,

whatever I do, mpicc or not, it is always the same result: MPI is disabled.

Hi Mathieu,

configure only checks if the MPI compiler is executable.

if test ! -x $mpicc_path; then
	AC_MSG_RESULT(The mpicc compiler is not valid)

You should change the message below the if
to print the value of $mpicc_path.

Ah, i just saw you specified a value to --with-mpicc, you
should not need to do that. It looks like your system is
finding a MPI runtime in /sw/xc40/xalt/0.5.4/sles11.3_gnu4.9.2/bin/

Cheers,

Nathalie
