Not sure how exactly you are configuring your environment, but it looks like you are actually building OpenMPI, not MVAPICH in your source build. In that case, you are having the same error with both MVAPICH and OMPI, which suggests that this is a system error
or an issue with your AOCC installation. I<span style="color: rgb(0, 0, 0);">f these libraries are in your runtime paths, they may also be impacting the RPM installation. In addition, the RPM you have is built with GCC 13 compilers, not AOCC so you will want
to make sure you have the same compiler installed.</span></div>

Hi,<br>
<br>
I am running into the same problem when building the tarball for MVAPICH 4.0 at <a href="https://mvapich.cse.ohio-state.edu/download/mvapich/mv2/mvapich-4.0.tar.gz">
https://mvapich.cse.ohio-state.edu/download/mvapich/mv2/mvapich-4.0.tar.gz</a> with the AMD AOCC compilers v5.0 and trying to use the RPM distribution of MVAPICH-Plus 4.0:<br>
<br>
When building MVAPICH 4.0, I get the following error message:<br>

I have been trying to figure out which library is supposed to provide these two symbols, without luck so far.<br>
<br>
Has anybody encountered the same problem?<br>
