From: Roi Martin <jroi.martin <at> gmail.com> To: 77918 <at> debbugs.gnu.org Subject: bug#77918: 31.0.50; Warnings about missing 'lexical-binding' cookie in *Async-native-compile-log* Date: Sat, 19 Apr 2025 10:41:35 +0200
Several warnings about missing 'lexical-binding' cookie show up in *Async-native-compile-log*. They seem to show up when a feature that has not been compiled yet is used and needs to be compiled. The issue is reproducible by just running 'emacs -Q'. You can find some of the warnings below. Warning (files): Missing ‘lexical-binding’ cookie in "/tmp/emacs-async-comp-dired-aux-xXuqdt.el". You can add one with ‘M-x elisp-enable-lexical-binding RET’. See ‘(elisp)Selecting Lisp Dialect’ and ‘(elisp)Converting to Lexical Binding’ for more information. Compiling /home/n/src/emacs/lisp/dired-aux.el... Compilation finished. Warning (files): Missing ‘lexical-binding’ cookie in "/tmp/emacs-async-comp-shell-rZsYYK.el". You can add one with ‘M-x elisp-enable-lexical-binding RET’. See ‘(elisp)Selecting Lisp Dialect’ and ‘(elisp)Converting to Lexical Binding’ for more information. Compiling /home/n/src/emacs/lisp/shell.el... Warning (files): Missing ‘lexical-binding’ cookie in "/tmp/emacs-async-comp-pcomplete-lO4nJm.el". You can add one with ‘M-x elisp-enable-lexical-binding RET’. See ‘(elisp)Selecting Lisp Dialect’ and ‘(elisp)Converting to Lexical Binding’ for more information. Compiling /home/n/src/emacs/lisp/pcomplete.el... Warning (files): Missing ‘lexical-binding’ cookie in "/tmp/emacs-async-comp-files-x-oLXnPa.el". You can add one with ‘M-x elisp-enable-lexical-binding RET’. See ‘(elisp)Selecting Lisp Dialect’ and ‘(elisp)Converting to Lexical Binding’ for more information. Compiling /home/n/src/emacs/lisp/files-x.el... Compilation finished. Warning (files): Missing ‘lexical-binding’ cookie in "/tmp/emacs-async-comp-rfc2047-XugClb.el". You can add one with ‘M-x elisp-enable-lexical-binding RET’. See ‘(elisp)Selecting Lisp Dialect’ and ‘(elisp)Converting to Lexical Binding’ for more information.

Note that I elided the native-comp-eln-load-path and load-path values to shorten the report.
