Hi Lance,
Can try adding the "--compiler=gcc" flag to your configure.py command? That
should use your custom gcc compiler since it's the first one that's found
on your path. When you run "make," you should see a line that looks like
"On MacOS, using gcc 4.8.5", but with your version of gcc. The latest gcc
that I have tested is 5.4.0 on Ubuntu 16.04, so I do not know if everything
will compile with gcc 6.3.0

Hello All-
How does one introduce an alternate gcc compiler for CCTBX on Mac? I must be missing it in the documentation.
I don’t want to use the old one in /usr/bin (and instead I want to you my newer one in /opt/gcc). I’ve tried all of the standard methods used by other build systems (change the $PATH, set $CXX and $CC, etc) but to no avail. These environment variables seem to be disregarded. We do use this compiler for building CCTBX on linux without too much trouble, so I think the support should be there.
Specifically:
mac-build64:build jenkins$ env | grep CXX CXX=/opt/gcc/current/bin/g++
mac-build64:build jenkins$ env | grep CC CC=/opt/gcc/current/bin/gcc
mac-build64:build jenkins$ which gcc /opt/gcc/current/bin/gcc
mac-build64:build jenkins$ g++ -v Using built-in specs. COLLECT_GCC=g++ COLLECT_LTO_WRAPPER=/opt/gcc/gcc-6.3.0-08092017/libexec/ gcc/x86_64-apple-darwin11.4.2/6.3.0/lto-wrapper Target: x86_64-apple-darwin11.4.2 Configured with: ../gcc-6.3.0/configure --prefix=/opt/gcc/gcc-6.3.0-08092017 --enable-languages=c,c++,fortran,objc --with-gmp=/opt/gcc/gcc-6.3.0-08092017 --with-mpfr=/opt/gcc/gcc-6.3.0-08092017 --with-mpc=/opt/gcc/gcc-6.3.0-08092017 --enable-libgomp --disable-multilib Thread model: posix gcc version 6.3.0 (GCC)

Thanks for your help!
