To install the branch from #12426, you need to use git. In a nutshell, add trac's git server to the remotes, and pull the branch u/fbissey/clang-progress from there. Something like git remote add trac git://trac.sagemath.org/sage.git git checkout -b foobar git pull trac u/fbissey/clang-progress and rebuild Sage: make distclean ./configure CC=cc CXX=c++ make More details may be found on http://doc.sagemath.org/html/en/developer/index.html# Shout if if you get stuck.. > > Regards, > Arvind > > On Sunday, 8 October 2017 16:44:44 UTC+5:30, Dima Pasechnik wrote: >> >> >> >> On Sunday, October 8, 2017 at 12:06:20 PM UTC+1, Arvind Ayyer wrote: >>> >>> Dear all, >>> >>> >>> I recently upgraded my Mac OS to HighSierra and have installed the >>> latest version of XCode.
