<p>Dear MPICH devs,</p>
<p>I want to use the MPI test suite provided with MPICH to test an
MPI wrapper library I am developing (the MPI wrapper for Score-P).
<br>
</p>
<p>As a first step, I tried to check out the latest version from
git, build everything and then run the test suite with `make
testing`. I can build MPICH itself without a problem and the
example cpi program runs just fine. However, during `make testing`
I run into lots of errors of the form</p>
<blockquote>
<p>In file included from dtpools.c:6:<br>
../include/dtpools_internal.h:12:10: fatal error: mpi.h: No such
file or directory<br>
12 | #include "mpi.h"<br>
| ^~~~~~~<br>
compilation terminated.</p>
</blockquote>
<p><br>
</p>
<p>This happens only with the git version, not with the tarball
version(mpich-4.0b1). <br>
</p>
<p>I attached all the program outputs and log files. Any help is
appreciated.</p>
<p><br>
</p>
<p>As I workaround I first built MPICH itself, then did './configure
CC=mpicc ...', in the test/mpi directory and then directly use the
runtests script. This works for now, but is surely not how it was
intended. <br>
</p>
<p>Kind regards,</p>
<p>Gregor Corbin</p>
