I have not updated the website to include the latest versions of amber tools, Xcode and GCC. However, if you run
$ gcc —version
I expect that you’ll see output including
Apple clang version 11.0.0 (clang-1100.0.33.8)
Meaning you are not using the GCC version you installed, hence the advice to use
./configure —macAccelearte clang
Should solve that problem. make sure that your system finds the fortran compiler as well.
With the latest version of OS X (10.14.6 (18G95)), Xcode (Version 11.0 (11A420a)) and GCC (9.2.0) I am currently unable to compile using the GNU compilers on OS X so you’d probably want to stay clear of that solution anyway for now.
Best regards
