So, I’ve been trying to do some *cough* quality testing of KDE, making sure it will build from scratch. Since I’m doing this, I figured I might as well upgrade GCC as well. So I get GCC 3.4.1 installed, no problems, and started compiling KDE.
Unfortunately, I was getting the weirdest errors. Stuff like undefined virtual thunks and such. It soundest like a libstdc++ problem, but g++ was using the correct version.
Turns out that the problem was that I was using distcc, and forgot to upgrade gcc on my other machine. I had even realized I was using distcc, and it still didn’t occur to me earlier. Go figure.
This is what makes icecream (in kdenonbeta) so nice. From what I understand, icecream will send over the GCC binary to each build machine, saving you the trouble of upgrading yourself. The catch is that GCC has to be compiled for the lowest common denominator machine, but that should be no big issue.
I’m suffering from too much inertia to switch now, but for all of you other distcc users, just remember: If you upgrade GCC on one machine, don’t forget to upgrade GCC on all of them!
