Hallo Dmitry, unfortunately the version 3.2.2 is the last mspgcc release available for download for linux from mspgcc's sourceforge website. There is also no a _really clear_ explanation which versions to compile and download with which patches to get all the toolchain running smooth.
I use 3.2.3, compiled with mspgcc patch CVS head for the 3.2.3 branch from end of july 2004 and it works quite well. The only downside is the lack of backtracing in my gdb (430x147), but I've promised myself, when I'll have some time to look at the issue and try to compile it for 6.2 and make the backtrace work. I've put my archives with a bit fresher runtime at http://www.pp.org.pl/~trevor/mspgcc/mspgcc_20040730.tar.bz2 Readme file how to install it (available also inside of the package) http://www.pp.org.pl/~trevor/mspgcc/README.txt - the versions and details are contained inside. It's still prefered to compile and and install from sources, but for people it can really simplify the life. Everything is inside, except gdbproxy - the licence issues of the tools don't permit to package it together. I'm not providing the sources, because it's compiled from one of the patch revisions available from mspgcc website and regular gnu tools distributions. The patch everyone can download from mspgcc website, there is no single modification by myself in the sourcecode. Regards, T.
