[Users] Error in exe/cactus_sim

[Rishank Diwan]

Hello Ian,

I am getting
"gcc -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi
-I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent
-I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent/include
-I/usr/lib/x86_64-linux-gnu/openmpi/include -pthread -L/usr//lib
-L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi" as result for "mpicc -show"
and "/usr/bin/mpicc" for "which mpicc"
which exactly the same as you mentioned.

Yours Sincerely,
Rishank Diwan
