Title:
oss4 does not build on ppc64el on groovy
Status in binutils package in Ubuntu:
Invalid
Status in oss4 package in Ubuntu:
Fix Released
Bug description:
When building the focal version of oss4 with groovy version of
binutils, it fails with:
/tmp/ccoZchTf.s: Assembler messages:
/tmp/ccoZchTf.s: Error: invalid attempt to declare external version name as
default in symbol `.snd_pcm_hw_params_set_rate_near@@ALSA_0.9.0rc4'
make[1]: *** [Makefile:16: pcm.lo] Error 1
Downgrading binutils to 2.34-6ubuntu1 fixes the problem. This works
with gcc-9 9.3.0-10ubuntu2. Upgrading to groovy gcc-9 9.3.0-17ubuntu1
will force the upgrade of binutils, so can't be tested with the
working version of binutils. Using the latest version of gcc-9 or
gcc-10 from groovy with the broken binutils is still broken, so a
complete upgrade does not fix the problem.
The following diff does fix the problem with binutils 2.35-2ubuntu1, though:
