Bug#681762: gcc-4.5 FTBFS on alpha: Failed link; work around is to link with --no-relax
Source: gcc-4.5
Version: 4.5.4-1
Severity: important
Tags: patch
User: debian-alpha@lists.debian.org
Usertags: alpha
X-Debbugs-CC: debian-alpha@lists.debian.org
Justification: Fails to build from source but built in the past.
gcc-4.5 FTBFS on alpha with GPREL16 relocation truncation errors in the
link of cc1-dummy during stage 1 compilation. Full build log is at:
http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.5&arch=alpha&ver=4.5.4-1&stamp=1341297050
The bug is a long standing bug in binutils that occassionally affects
linking of very large packages. Unfortunately the use of gcc-4.6 tends
to trigger it more often and it is now affecting the build of gcc-4.5.
The known work around is to disable relaxation in the linker and the
link will then complete successfully.
I can manually inject -Wl,--no-relax into the link of cc1-dummy during
the stage 1 compilation, rerun "debian/rules build", manually inject
-Wl,--no-relax into the link of cc1, rerun "debian/rules build" again,
and then the build completes successfully. (My attempts at producing a
patch to debian/rules2 to automatically inject the -Wl,--no-relax option
into the stage 1 compilation links failed so no patch attached here, sorry.)
The old version of gcc-4.5 at debian-ports currently breaks installation
of the Alpha port with debootstrap, so an upload of a fix would be very
much appreciated, but we will understand if this is not possible because
of the freeze.
Cheers
Michael.
