Hi,
I see a new directory on alioth named gcc-3.4, which seems to contain
alot of packages. I guess that this is all the packages compiled with
gcc-3.4, which generates better code for x86-64 than gcc-3.3.
Is this a complete port (compared to pure64 on alioth) or should I sill
have pure64 in my sources.list for packages that are not yet compiled
using gcc-3.4?
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 read that gcc 3.4 has changed
ABI from gcc 3.3, but I'm not sure which architectures this affectes.
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.
