graphicsmagick fails to compile with gcc-5 in superenv

[felixbuenemann]

I'm trying to enable openmp support in the graphicsmagick formula, which causes a compilerswitch to from clang gcc-5.

Howerver compilation fails due to some issue with the homebrew build environment. If I compile graphicsmagick outside of homebrew it compiles fine, so it does not seem to be a general issue with gcc 5, but rather how superenv sets up the environment.

To reproduce use: brew install graphicsmagick --cc=gcc-5 and make sure the gcc formula is installed.

The errors are:

libtool: link: gcc-5 -g -O2 -Wall -D_THREAD_SAFE -o utilities/.libs/gm utilities/gm.o  -L/usr/local/Cellar/freetype/2.6_1/lib -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib magick/.libs/libGraphicsMagick.dylib -lfreetype -llzma -lbz2 -lz -lltdl -lm -lpthread

I'm happy to post more detailed info if you can't reproduce. System is 10.11.4-x86_64 / Xcode 7.2.

I see an identical error with CC=gcc-5 CXX=g++-5 ./configure --prefix $PWD/install --with-modules --without-x --enable-shared --disable-static --disable-openmp --with-quantum-depth=16 && make outside of Homebrew: https://gist.github.com/tdsmith/4567625468d40780a96b

[felixbuenemann]

Hmm, I just used CC=gcc-5 CXX=g++-5 ./configurewhen compiling outside homebrew. If I use your flags it also fails…

[felixbuenemann]

If I remove --enable-shared --disable-static the compile works.

If this is still broken: we'll accept PRs for this but we're not actively working on it at this time.
