For this reason, I mailed to the homebrew people, and got this response: "What compiler are you using? Do you have Homebrew gcc installed?" After installing gcc-11 from homebrew, and inserting the line export CC="/usr/local/Cellar/gcc/11.1.0/bin/gcc-11” in my .bash_profile, the “smoke test" error message (about which this disussion started) was gone and I could build Emacs with the native compile option. > > (And maybe we should ping the GCC developers to finish the work on the > features needed to build Emacs -- there's a Bugzilla PR, where, last > time I checked, there was some work being done).
