@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.
@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 ah, thanks!!
@jautero `make extraclean` and `make -j1` did the trick.
@jautero well, that's not a helpful suggestion. i think the problem is related to "make clean" not cleaning out all .elc and dump files of previous builds, so tried to do that manually now. also i'm trying to compile with -j1
