So I tried to set the following environment variables. Experimented with various permutation combinations of these. #+begin_src elisp (add-to-list 'exec-path "/usr/local/opt/gcc/bin") (setenv "PATH" (mapconcat 'identity exec-path ":")) (setenv "LD_LIBRARY_PATH" "/usr/local/opt/libgccjit/lib/gcc/10:/usr/local/opt/gcc/lib/gcc/10") (setenv "LIBRARY_PATH" "/usr/local/opt/libgccjit/lib/gcc/10:/usr/local/opt/gcc/lib/gcc/10") #end_src The above are standard location of ‘gcc’ and ’libgccjit’ artifacts. The exec-path configuration above crashes my Emacs at startup. So I had to comment that out. Is there a way in Emacs to get all the environment variables in one go? I want to compare the vars from two invocations - GUI and CLI. As I reported earlier that CLI invocation works without any error. More facts: The error comes only at the beginning. As you can see in the following log (*Async-native-compilation-log) that compilation is working fine later on. --8<---------------cut here---------------start------------->8--- Compiling /Users/pankaj/Applications/Emacs.app/Contents/Resources/lisp/emacs-lisp/cl-lib.el.gz... uncompressing cl-lib.el.gz... uncompressing cl-lib.el.gz...done ld: library not found for -lgcc_ext.10.5 libgccjit.so: error: error invoking gcc driver /Users/pankaj/Applications/Emacs.app/Contents/Resources/lisp/emacs-lisp/cl-lib.el.gz: Error: Internal native compiler error failed to compile Compiling /Users/pankaj/Applications/Emacs.app/Contents/Resources/lisp/emacs-lisp/crm.el.gz... uncompressing crm.el.gz... uncompressing crm.el.gz...done Compiling /Users/pankaj/Applications/Emacs.app/Contents/Resources/lisp/progmodes/hideshow.el.gz... uncompressing hideshow.el.gz... uncompressing hideshow.el.gz...done Compiling /Users/pankaj/Applications/Emacs.app/Contents/Resources/lisp/emacs-lisp/advice.el.gz... uncompressing advice.el.gz... uncompressing advice.el.gz...done Compiling /Users/pankaj/Applications/Emacs.app/Contents/Resources/lisp/outline.el.gz... uncompressing outline.el.gz... uncompressing outline.el.gz...done Compiling /Users/pankaj/Applications/Emacs.app/Contents/Resources/lisp/calendar/cal-menu.el.gz... uncompressing cal-menu.el.gz... uncompressing cal-menu.el.gz...done --8<---------------cut here---------------end--------------->8--- And when all the compilation is done the error goes away; it does not appear in further sessions.
