Rename Fortran requirement to fix option generation So, `depends_on :fortran => :optional` will generate "--with-fortran" rather than "--with-fortranRequired". 2013-06-25 21:08:59 -05:00			`class FortranDependency < Requirement`
Add :fortran requirement 2013-06-23 18:35:20 -07:00			`fatal true`

fortran_dependency: use gcc instead of gfortran. 2014-05-15 21:03:12 +01:00			`default_formula 'gcc'`

FortranDependency: make sure gfortran ends up in PATH Per requirements.rb: > XXX If the satisfy block returns a Pathname, then make sure that it > remains available on the PATH. This makes requirements like > satisfy { which("executable") } > work, even under superenv where "executable" wouldn't normally be on the > PATH. > This is undocumented magic and it should be removed, but we need to add > a way to declare path-based requirements that work with superenv first. Fixes homebrew/homebrew-python#170. Closes Homebrew/homebrew#38448. 2015-04-07 16:37:22 -07:00			`which(ENV["FC"] \|\| "gfortran")`
