FFmpeg 2.7.2 fails to build on MIPS

Reported by: brad Owned by:

Version: git-master Keywords: mips
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: yes


Switching from FFmpeg 2.7 to 2.7.2 there has been a regression with building on MIPS. The build uses all of the various command line parameters to disable the various MIPS features for newer chips..

--disable-loongson3 --disable-mips32r5 --disable-mips64r6 --disable-mipsdspr1 --disable-mipsdspr2 --disable-msa

The compiler is GCC 4.2.1.

The build fails like so..

In file included from libavcodec/mips/hevcdsp_init_mips.c:21:
./libavcodec/mips/hevcdsp_mips.h:35:1: error: pasting
"ff_hevc_put_hevc_pel_pixels" and "##" does not give a valid preprocessing

  • Priority changed from important to normal

Please update your compiler and please test current FFmpeg git head.
To make this a valid ticket, please provide your configure line, run make V=1 several times and provide the complete, uncut console output of the last run.

I'll check git master, but the compiler isn't changing. This is what it has to build with and what we've used to build FFmpeg for quite a few releases now.

Are you sure it worked with ffmpeg 2.7, or you meant to say 2.6?
The line that gives that error has been in the tree since the 2.7 release and hasn't changed since. The entire mips folder apparently hasn't changed from 2.7 to 2.7.2, even.

Can you try the attached patch and see if it fixes the error for you?

Ok, taking your patch and expanding upon it to cover the other macros that were having issues compiling it is now compiled Ok and working.
