I’m following the other post: Building cmdstan 2.20 with mpi enabled on Linux
I tried creating a file make/local and then adding:
STAN_MPI=true
CXX=mpicxx
TBB_CXX_TYPE=gcc
But that didn’t work, I got
bash: mpicxx: command not found
So I edited the local file:
STAN_MPI=true
CXX=g++
TBB_CXX_TYPE=gcc
and made it most of the way through the build process until:
