How to tell to a 'configure' file to compile with a specified version of g++ ?
Thanks.
In a bash shell you can do something like this:
CC=gcc-2.95 ./configure
There will be similar techniques for other shells but I couldn't help you with the specifics. If your project is C++ the variable you need to define is CXX.
