After finally figuring out how to install all the required packages for haskell-mpi, I run:
sudo cabal install --global haskell-mpi
and, it gives a header error:
Resolving dependencies...
Configuring haskell-mpi-1.2.1...
Preprocessing library haskell-mpi-1.2.1...
dist/build/Control/Parallel/MPI/Internal.chs.h:1:17: error: mpi.h: No such file or directory
c2hs: Error during preprocessing custom header file
cabal: Error: some packages failed to install:
haskell-mpi-1.2.1 failed during the building phase. The exception was:
ExitFailure 1
How do I link the header?
