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

Does it work if you link with -latomic ?

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#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.
