Maintaining multiple builds for different compiler versions

Question

I am developing a C++ library and I use a Makefile to compile and create a build. I wish to maintain multiple builds for different gcc compiler versions. What is the best way to do this?

If you are ready to go with autotools, autoconf/automake let you do this through out of tree builds . You can configure as many build you want if you separate each build into its own directory (not the source directory).

Configuring compiler and compiler options is usually a simple matter of bash command line.

mkdir mingw-build
cd mingw-build
CXX=mingw32-g++ ../myproject/configure ...
cd ..

mkdir native-build
cd native-build
CXX=g++ ../myproject/configure ...
cd ..
