Is there some possibility 4.2 might be included in addition to 4.0, but that 4.0 could be the default behavior?
Xcode 3.1.x has definitely both. Unless they messed around with the installation, g++-4.2 will always call gcc 4.2 and g++-4.0 will call gcc 4.0. The only question is which is default and you can change the default (e.g. via gcc_select or directly with the symlinks). What I don't remember is what is the default in which version - and I think it may also depend on whether you upgraded or not - but I just don't remember it's been too long ;). Cheers, Simon
This might be consistent with the following email from my student (though it's also possible that she did some installation improperly). I'm starting to think I ought to have a Mac in my office to play around with. !-) --------------------- It seems i have g++4.2 on my mac. dhcp128036180037:R-2.12.2 Grace$ /Developer/usr/bin/g++-4.2 i686-apple-darwin9-g++-4.2.1: no input files But, still, seems does not call by g++ --version. dhcp128036180037:R-2.12.2 Grace$ g++ --version i686-apple-darwin9-g++-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5493) Copyright (C) 2005 Free Software Foundation, Inc.

I double checked I indeed have "Xcode 3.1.3", unless it's a fake name or I did not install correctly. I installed the XcodeTools package and later the gcc4.2 package. -- John W.
