Bug#836327: gsequencer: FTBFS on mips and powerpc: ags_functional_audio_test segmentation fault

2016-10-11 Thread Dejan Latinovic 


Any updates on this issue?

I have tested newer releases (0.7.73 and 0.7.83) on local mips machine, both 
build failed with  Segmentation fault:

Bug#830886: ffmpeg FTBFS for mips64el on configure

2016-07-12 Thread Dejan Latinovic 
Package: ffmpeg
Version: 7:3.0.2-1
Severity: serious
Tags: sid, patch
Justification: FTBFS
User: debian-m...@lists.debian.org
Usertags: mips-patch


Package ffmpeg FTBFS for mips64el on configure with the following error:
> ERROR: LoadLibrary/dlopen not found for avisynth

Error message from config.log:
> /usr/bin/ld: /tmp/ffconf.09oJ6qCG.o: linking -mnan=2008 module with previous 
> -mnan=legacy modules
> /usr/bin/ld: failed to merge target specific data of file 
> /tmp/ffconf.09oJ6qCG.o
> collect2: error: ld returned 1 exit status

The reason for that is usage of -mips64r6 flag that triggers -mnan=200 flag.

Solution is to disable mips64r6 in debian rules.
Patch that includes this fix is attached.

I will rebuild locally latest ffmpeg version (7:3.1.1-1) for 
mips/mipsel/mips64el to confirm that patch fixes mips64el and does not break 
mips/mipsel.

Bug#771556: x265: FTBFS on powerpc

2014-12-03 Thread Dejan Latinovic 



Hello Sebastian,

the patch is attached.

Please try it on ppc,
I hope that the condition for ppc arch is correct.


Here you can see related issue, with more info:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=748932

I had noticed that idba still FTBFS on ppc.
Could you also test my patch posted on #748932?

It is needed to update condition to cover pcc.

Bug#771556: x265: FTBFS on powerpc

2014-12-02 Thread Dejan Latinovic 


Mips platform does not have 64-bit __sync_* operations.
To avoid this behavior it is needed to use
corresponding __atomic_* from libatomic library.

I was able to successfully built x265 for mipsel.

I will prepare the patch,
so Sebastian could test it on powerpc.

Regards,
Dejan

  powerpc porters, do you have any idea what the problem is? Are
  __sync_val_compare_and_swap and __sync_or_and_fetch not supported on
  powerpc?

 The builds for mips and mipsel have failed with the same issue. I'm also
 CCing the mips porters in the hope that they can shed some light on the
 problem.

Does it work if you link with -latomic ?

James
