Uncompress a downloaded pre-compiled archive into a directory and just use it from there (AFAIK, very common under macOS and Windows)? With luck on some systems the C (or other) compiler is installed in a similar way (i.e. in its own subdirectory, siloed from Emacs). >> When the compilation of the module is initiated from within Emacs, it >> would make a lot of sense for this "ambient" Emacs to be able to tell >> `make/gcc/younameit` explicitly and reliably where its own >> `emacs-module.h` can be found. > But if Emacs is "not installed properly", we don't know that. Emacs *should* know that, just like it knows where is its `lisp-directory`. Stefan
