Currently all packages are being recompiled with gcc-3.4 as the default compiler. The resulting packages are being uploaded to the new repository in the gcc-3.4 directory. Every package is being compiled in clean chroot environment with only the specified Build-Depends installed. Building about 8500 packages takes some time even on an amd64 machine. At the moment the gcc-3.4 repository has about 1200 packages and it includes all packages with priorities 'Required', "Important' and 'Standard' as well as all packages from the base system which are necessary to debootstrap a chroot environment. However, the upload of the missing ~7000 packages will take a few more days. > Also, is there any issues to be aware of when mixing gcc 3.4 compiled > packages with gcc 3.3 compiled packages?

I would recommend _not_ to use the packages from the gcc-3.4 repository until the conversion of the archive has been completed. C++ programs compiled with g++-3.3 use the library from the libstdc++5 package while programs compiled with g++-3.4 use the one from libstdc++6. There are (minor) incompatibilities between those two libraries. Regards Andreas Jochens
