./configure with a specified version of g++

How 开发者_开发技巧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:

./configure CC=gcc-2.95

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.
