I am a beginner in Emacs. After installing the SLIME environment, I keep receiving the following warnings when I open Emacs:
Warning (comp): c:/Program Files/Emacs/emacs-28.2/share/emacs/28.2/lisp/emacs-lisp/pp.el: Error: Internal native compiler error failed to compile Disable showing Disable logging
Warning (comp): c:/Program Files/Emacs/emacs-28.2/share/emacs/28.2/lisp/progmodes/project.el: Error: Internal native compiler error failed to compile Disable showing Disable logging
Warning (comp): c:/Program Files/Emacs/emacs-28.2/share/emacs/28.2/lisp/progmodes/gud.el: Error: Internal native compiler error failed to compile Disable showing Disable logging
Are they crucial and how should I deal with them?
I searched the internet regarding the warnings but I failed to get useful information. Moreover, I do not experience any crucial errors when I test basic Lisp programming in Emacs though.
I keep receving the following warning as I open emacs. Are they crucial ...?
They are not crucial in a sense these errors don't prevent Emacs from working, which you confirmed yourself. But if you don't like error messages and like (significantly) faster-working Emacs, then let's move on to
how should I deal with them?
Probably start with reading a few paragraphs: M-: (info "(elisp) Native Compilation") RET or in online manual, to get an overall understanding what the error message is about. Namely:
In addition to the byte-compilation, described in the previous chapter, Emacs can also optionally compile Lisp function definitions into a true compiled code, known as “native code”. This feature uses the ‘libgccjit’ library, which is part of the GCC distribution, and requires that Emacs be built with support for using that library. It also requires to have GCC and Binutils (the assembler and linker) available on your system for you to be able to native-compile Lisp code.
From this text, we can understand that the error reported means Emacs couldn't (natively) compile the files. And our first look should probably be towards checking if libgccjit library can be used by Emacs.
I guess the following EmacsSE threads: ‘Error: junk at end of line’ with native-comp and Is there a gccemacs (native-comp) build for MS-Windows? may provide helpful info for your case.
If that doesn't help, post more info on which way was your Emacs installed/compiled, more details about your environment, and output of M-: (native-comp-available-p) RET.
And, in a case you're a type of person who likes diving into more details, the article Bringing GNU Emacs to Native Code could be invaluable.
