[SOLVED] Simple and reliable way to build a project with custom gcc

I have to build a big C/C++ project with GCC-4.9. I've installed gcc49 from AUR alongside with the base GCC, which has the same executable names as the base GCC plus the suffix "-4.9".

What is the best way to tell the primary configure/make command to use GCC-4.9 executables instead of the main GCC? Is there something simpler than creating symlinks/aliases for each toolchain executable or digging up all places in makefiles where the compiler is specified?

If the makefile is using the standard variables, then you can set them
https://www.gnu.org/software/make/manua … ables.html

Otherwise symlinks should be the way to go, but that can be automated similar to a python venv.

for file in /usr/bin/*-4.9; do make_venv_symlink; done
