@mntmn Don't try to compile random emacs branches if you can't debug elisp? Latest commit lead me to this help text, though. https://github.com/flatwhatson/emacs/blob/64425ee0d82632c71839aa615256e9a438e1d62a/lisp/emacs-lisp/comp.el#L187-L189
If font-core.el doesn't compile, then don't compile it.
@jautero what do you mean "random", i want specifically this branch
@mntmn Random as in not a release branch / main development branch. (Or basically any branch not hosted in Savannah.)
@mntmn You're probably right since there are make targets `distclean`, `maintainer-clean`and `extraclean`.
@jautero `make extraclean` and `make -j1` did the trick.
@jautero ah, thanks!!
