GCC 3.3 doesn't support the -mno-sse3 flag. As a result, the ebuild fails as soon as it is run, failing with an error when it tries to determine the object file extension. Reproducible: Always Steps to Reproduce: Edit the code in the ebuild and remerge. The original code snippet: # fix build errors with sse2 #49482 if use x86 ; then [ "`gcc-version`" == "3.2" ] && append-flags -mno-sse2 && filter-mfpmath sse [ "`gcc-version`" == "3.3" ] && append-flags -mno-sse2 -mno-sse3 && filter-mfpmath sse [ "`gcc-version`" == "3.4" ] && append-flags -mno-sse2 -mno-sse3 && filter-mfpmath sse fi Just cut out the -mno-sse3 from the GCC 3.3 line and it works fine. Actual Results: Works after you edit the ebuild
Strange. The online doc show -mno-sse3 option: http://gcc.gnu.org/onlinedocs/gcc-3.3.3/gcc/i386-and-x86-64-Options.html#i386%20and%20x86-64%20Options
maybe gcc-3.3.3 does but how about gcc-3.3.0 to gcc-3.3.2 ?
Yes it's true that sse3 is only added in gcc-3.3.3. BTW, gcc-3.3.3 is *stable* on x86.

I can confirm the bug, while 3.3.3 may now be marked stable, it is not what is included on the 2004.1 tarballs. The ebuild should atleast check the minor revision numbers.
fixed in cvs
