brew install open-mpi fails

Question

Trying to install openmpi, read that:

Could not determine if REAL*16 bit-matches C type

Ran brew doctor, and it's giving me:

Your system is raring to brew

full output

Which C and Fortran compilers are installed? – Lindsley

To me this looks like it's trying to use a Fortran compiler and then complaining that it cannot see if the results are compatible with C. Maybe try installing GCC as your compiler for Homebrew instead and try again? – Kraut

This behaviour might be intended if Fortran and C object files are used in the same application. But I also suggest installing gcc and gfortran and then try again. – Lindsley

Waiting for your answers, I tried with an older version of open-mpi, and it works without any problem. I have already install gcc and gfortran before Open-mpi. – Shoshonean

Answer 1

There were some issues with recent gfortran builds in Homebrew. Try reinstalling it with brew rm gfortran; brew install --fresh gfortran. If the error persists, head over to the Homebrew GitHub page and report it as a bug: https://github.com/mxcl/homebrew/wiki/Troubleshooting.

Answer 2

There seems to be an issue with the gmp and mpfr bottles, which are dependencies of gfortran and thus open-mpi. Try doing brew rm gmp mpfr; brew install --build-from-source gmp mpfr open-mpi
