I'm a new linux user. I'm getting this error during compilation. When I use the 'make' command within a build directory.
Fatal Error: mpi.h No such file or directory
I've installed OpenMpi using this:
sudo apt install libopenmpi-dev
I found the folder where mpi.h is located: and I attempted to add it to path:
export PATH=$PATH:/usr/lib/x86_64-linux-gnu/openmpi/include
I still get the same error when I try 'make'. What am I doing wrong? Thanks.
Edit: I think I'm using the G++ compiler, here's the full error message:
