<br class="">
I installed openmpi with gcc7 by:<br class="">
<br class="">
$ sudo port install openmpi +threads<br class="">
…<br class="">
$ port installed | grep openmpi<br class="">
openmpi @1.10.3_0 (active)<br class="">
openmpi-default @1.10.3_0+gcc7+threads (active)<br class="">
$ port select mpi<br class="">
Available versions for mpi:<br class="">
none<br class="">
openmpi-mp-fortran (active)<br class="">
<br class="">
However, gcc is not invoked by the mpi wrapper:<br class="">
<br class="">
$ which mpicc<br class="">
/opt/local/bin/mpicc<br class="">
$ mpicc --show<br class="">
/usr/bin/clang -I/opt/local/include/openmpi-<wbr class="">mp -L/opt/local/lib/openmpi-mp -lmpi<br class="">
<br class="">
It is using Apple’s native, not gcc at all. And the mpi wrapper is a series of links to opal_wrapper, which is a binary.<br class="">
<br class="">
Has anyone had this problem also? Is it a bug in the port file? How can I fix this without installing openmpi-gcc7 and force the mpi selection?<br class="">
<br class="">
Sincerely,<br class="">
