The latest (as of this writing) GCC port to FreeBSD 9.0 ended up creating some compile problems when I did a
portupgrade -ra: /usr/ports/graphics/tiff couldn’t find some libraries:
g++46: error: /usr/local/lib/gcc46/gcc/x86_64-portbld-freebsd9.0/4.6.3/crtbeginS.o: No such file or directory g++46: error: /usr/local/lib/gcc46/gcc/x86_64-portbld-freebsd9.0/4.6.3/crtendS.o: No such file or directory *** Error code 1
The problem is that there is no more 4.6.3 directory once you install 4.6.4. I didn’t bother debugging the port problem, though I probably should have and informed the port maintainer and all of those good citizenship steps but instead took a shortcut that solved the problem:
cd /usr/local/lib/gcc46/gcc/x86_64-portbld-freebsd9.0/ ln -s 4.6.4 4.6.3 cd /usr/ports/graphics/tiff make clean portupgrade -ra
And all is good.
