Bug#156662: gcc 3.2 will need Depends and Build-Depends on binutils and glibc versions for ppc
Package: gcc-3.2
Version: 3.2_3.2-0pre4
Severity: grave
On ppc, there will be version requirements, for properly building
and installing gcc-3.2, on the glibc and binutils installed. See
bug report 155606 for a description of this issue. The needed binutils
will likely be version 2.13.90.0.4-1 and, with luck and
cooperation, the correct libgcc-compat.S patches will be in
glibc 2.2.5-14. Without the Build-Depends on both these versions
of binutils and glibc, a libgcc_s.so.1 will be created with
missing versioning on the __divdi3 symbol on ppc. Also without
the Depends on these versions of glibc and binutils, there
can be problems building programs with gcc 3.2 on ppc due to
bugs in binutils fixed in current binutils-cvs (and the next
release, 2.13.90.0.4). Specifically, binutils will incorrectly
report a symbol conflict on __divdi3 which doesn't exist when
libc.so.6 is really only providing __divdi3 for run-time
resolution and NOT for linking. This has been fixed in binutils-cvs.
If we don't add the Build-Depends on binutils (>= 2.13.90.0.4)
and glibc (>= 2.2.5-14) for gcc-3.2 , we won't be able to properly
build gcc-3.2 against glibc 2.2.5-14 with the corrected
libgcc-compat.S code. If we don't add the Depends on the above
binutils and glibc versions, when gcc-3.2 becomes the default
compiler for builds in debian sid on ppc, we risk the build
machine getting out of sync and not building able to link programs.
Thanks in advance for slating this for the final gcc-3.2 release
(after Chris releases the new 2.13.90.0.4 binutils when it arrives
and glibc adopts the needed libgcc-compat patch from bug report
155606 or resamples glibc upstream once Franz Sirl has that
added there).

ps Franz Sirl should be submitting his patch to libc-alpha today.
