sage: latest version (8.1) (from https://github.com/sagemath/sage, last updated Dec 17, 2017). tried both master branch and develop branch. OS: Mac OSX 10.13.3 Xcode version 9.0.1
I cloned the latest version of sage from the git repository. When attempting to `make` sage, I run into the error `The following package(s) may have failed to build...gfortran-7.2.0`. I will attach the log file shortly. Near the bottom of the file it says: The directory that should contain system headers does not exist: /usr/include make: *** [stmp-fixinc] Error 1 make: *** Waiting for unfinished jobs.... rm gcc.pod gfortran.pod make: *** [all-gcc] Error 2 make: *** [all] Error 2 I tried using brew to manually install gfortran. Brew said that it ships with gcc. I used brew to update my system to the latest version of gcc. It didn't help. Currently, I am updating my Xcode to 9.2 to see if that helps. Also, should my "system headers" exist? If so, where are they? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
