[SOLVED] CMake Error: CMAKE_C_COMPILER not set

[pmlefeuvre]

Hi,

I got a compiler error during a re-installation of elmer using homebrew on my OSX 10.12.4. This error is the same than in issue#5 (see below). It could not find my current gcc version (gcc-7) and by default assigned gcc-8 which caused a version conflict with my gfortran-7.

The editing of the compilers in elmer.rb (l. 47-48) did the job as advised in issue#5 . Is it possible to edit the way it finds gcc compilers in future versions?

Edited lines in /usr/local/Homebrew/Library/Taps/elmercsc/homebrew-elmerfem/elmer.rb ENV["CC"] = "/usr/local/Cellar/gcc/7.1.0/bin/gcc-7" #edited ENV["CXX"] = "/usr/local/Cellar/gcc/7.1.0/bin/g++-7" #edited # ENV["CC"] = "#{Formula["gcc"].opt_bin}/gcc-#{Formula["gcc"].version_suffix}" # ENV["CXX"] = "#{Formula["gcc"].opt_bin}/g++-#{Formula["gcc"].version_suffix}"

Error Message after: brew reinstall -verbose elmer --HEAD --with-elmerice

The rest of the compilation went smoothly. Thanks for the otherwise easy homebrew installation of elmerice.
