Is it possible to install multiple versions of Intel C++ Composer XE for Linux on the same distro, mainly the 2011 and the 2013 versions ? If so, what are the steps which will allow one or the other to be used at a time ? I need to be able to test both against code I have writen.
Installing to default locations (or any suitable choice of separate install paths) should support this. You would source the compilervars script of the one you want to use, so that one comes first on PATH and LD_LIBRARY_PATH. A fancier way is by the modules facility : http://modules.sourceforge.net/
