Hi all,
I've been using SIP to generate bindings for Syzygy
<http://www.isl.uiuc.edu/syzygy.htm>. Since we've been using GNU Make
for everything, I've been running SIP with "-j 1" to generate a single
.cpp file, which up til now has worked fine (with MinGW g++ 3.4.2 on
Windows and whatever g++ comes with Ubuntu 7.10).
However, I'm trying to upgrade to Ubuntu 8.04, which includes g++ 4.2.3.
Building the bindings on my Windows machine takes about 35 seconds. On a
fairly similar ubuntu machine, I gave up after about _half an hour_. On
a blazing-fast, high-end, chock-full-o-RAM graphics machine it completed
after 15 minutes or so, I wasn't timing.
Has anyone else run into this problem?
Yes, it's a known bug in GCC 4.2 serie which won't be fixed.:

Your best bet is to upgrade to GCC 4.3 (which isn't packaged yet in
Ubuntu) or downgrade to GCC 4.1 (which is packaged -- but then you have
to manually modify the symlink /usr/bin/gcc to point to the correct
version).
