I restarted my laptop and then Just typed (using tcsh shell) ./configure CFLAGS='-O0 -g3' --enable-checking='yes,glyphs' --enable-check-lisp-object-type --prefix=/opt/emacs27 --wi th-x-toolkit=athena --with-mailutils And that worked. I could compile emacs succesfully. So maybe I owe you an apology. But think if I am correct that should be written in src/DEBUG: The line reads CFLAGS='-O0 -g3' ./configure --enable-checking='yes,glyphs' --enable-check-lisp-object-type When I run it I obtain CFLAGS=-O0 -g3: Command not found. Which is to expected. So it should be ./configure CFLAGS='-O0 -g3' --enable-checking='yes,glyphs' --enable-check-lisp-object-type > You should type literally the command as written in DEBUG. Not for me. Ok I just checked it seems to work for the bash shell. In that case still a correction should be in place. Don't you think so.
