<br>
I am currently trying to compile my code but the compilation fails with <br>
the following error:<br>
<br>
error "PETSc was configured with OpenMPI but now appears to be compiling <br>
using a non-OpenMPI mpi.h<br>
<br>
I have obviously checked and I am compiling my sources using the same <br>
compiler used to compile Petsc. To check this, I looked into the <br>
configure.log file generated by petsc and verified that the compiler <br>
listed was indeed the one currently been used to compile my sources.<br>
<br>
Does anyone have any idea of where the problem might be coming from?<br>
<br>
Thank you,<br>
<br>
D.<br>
