How to use an older version of gcc in Linux

Question

In Linux I am trying to compile something that uses the -fwritable-strings option. Apparently this is a gcc option that doesn\'t work in newer version of gcc. I installed gc

Answer 1

You say nothing about the build system in use, but usually old versions of gcc can be invoked explicitly, by something like (this is for an autotools-based build):

./configure CXX=g++-3.4 CC=gcc-3.4

For a make-based build system, sometimes this will work:

make CXX=g++-3.4 CC=gcc-3.4

Most makefiles ought to recognise overriding CC and CXX in this way.
