When installing Emacs using the installer (emacs-28.2-installer.exe),
by default it adds the compiler and libraries (gcc and libgccjit)
to the ./bin directory without prompting the user for his opinion.
The problem appears when another compiler is already installed in the
system, eg. from MinGW. Emacs then tries to use the libraries from PATH
instead of those installed in its subdirectories:
Warning (comp): c: /tools/emacs/share/emacs/28.2/lisp/org/org-entities.el:
Error: Internal native compiler error failed to compile
Warning (comp): C: \\ ProgramData \\ chocolatey \\ lib \\ mingw \\ tools \\
install \\ mingw64 \\ bin \\ libgccjit-0.dll: error: error invoking gcc
driver
When I tried to find a solution to the problem, I found something like
this:
M-: (executable-find "gcc") RET
"c:/ProgramData/chocolatey/bin/gcc.exe
M-: (executable-find "as") RET
"c:/ProgramData/chocolatey/bin/as.exe"
etc, etc
But should be:
C:\Program Files\Emacs\emacs-28.2\bin\gcc.exe
C:\Program Files\Emacs\emacs-28.2\bin\as.exe
The only solution I have found so far is to uninstall the "global"
MinGW, then emacs uses the embedded libraries and everything is fine.
