Common Issues

Cyclic dependency for gcc

Error looks like this

gcc asks for zlib, and zlib asks for gcc !

$ brew install gcc
==> Installing dependencies for gcc: zlib, gmp, mpfr, libmpc, isl
==> Installing gcc dependency: zlib
Error: zlib cannot be built with any available compilers.
To install this formula, you may need to:
  brew install gcc

Possible solution:

brew install opam --cc=gcc
