to my defense: the INSTALL instructions of Gambit and its different combinations are not so trivial and this specific trinity cannot be found in this exact form. But it now that I know it makes perfect sense...
It did compile, even with the -j8 switch
thanks alot

Please read the build steps in the INSTALL.txt file… When freshly cloned from github, Gambit needs to be bootstrapped, so you need to *precisely* follow these steps:
% ./configure --enable-single-host CC=gcc-6 % make current-gsc-boot % make from-scratch
The “./configure …” followed by “make” that you are using is appropriate when building from a release of Gambit, for example v4.8.8 with no other patches applied.
So above the “make current-gsc-boot” builds the latest release of Gambit by using git to checkout the latest release (v4.8.8 currently) and then creates boot/gsc/gsc which is then used by the “make from-scratch” to bootstrap Gambit using the repo HEAD.

I couldn't install gcc-7 with brew but gcc-6.
This will not compile:

By default the configure script searches for gcc before looking for clang. However… X-code installs “clang” and also “gcc”, and that “gcc” is not the GNU gcc… it is a wrapper around clang/llvm. So to install the GNU gcc you need to use homebrew like this:
% brew install gcc-7
and then tell the configure script to use that compiler:
% ./configure --enable-single-host CC=gcc-7
You will notice a dramatic decrease in compilation time and in execution time (about 3 or 4 times faster execution if I recall correctly). On my machine a “make -j8” after a “make clean” takes 30 seconds.

hi On macos sierra running the ./configure script gives me the following message:

What can I do to enforce GCC? I cannot see any specific configure --options
Attached you'll find the entire configure log.
Thanks, Ben
