gcc-3.1?
# g++ -v Reading specs from /usr/lib/gcc-lib/i586-pc-linux-gnu/2.95.3/specs gcc version 2.95.3 20010315 (release) # gcc -v Reading specs from /usr/lib/gcc-lib/i586-pc-linux-gnu/2.95.3/specs gcc version 2.95.3 20010315 (release) Both binaries are dated yesterday, July 4, since I just updated world. However, I should mention that this machine *was* gcc3.1 for a while before I converted back to 2.95 again, so I'm suspicious that there may still be something peculiar to this machine because of that. I recompiled everything after converting back many weeks ago and this is the only compilation error I've seen since then. Just to be sure: # cc -v Reading specs from /usr/lib/gcc-lib/i586-pc-linux-gnu/2.95.3/specs gcc version 2.95.3 20010315 (release) # c++ -v Reading specs from /usr/lib/gcc-lib/i586-pc-linux-gnu/2.95.3/specs gcc version 2.95.3 20010315 (release) This is the only package that won't compile, so the problem has to be subtle.
Ha! I didn't realize that I couldn't just re-emerge gcc-2.95 and rebuild everything. I didn't specificially unmerge gcc-3.1 and it turns out that leaving those files around must have fooled autoconf into mis-configuring avifile for g++3.1 (or something). When I did an 'unmerge' of gcc-3.1 the problem went away. Interesting that 'emerge clean' did not pick up the multiple versions of gcc and offer to unmerge one or more.
