Wierd compiler errors
 

I'm trying to make a library called librtk and I get the following error:

../librtk/librtk.a(motion_est_mmx.o)(.text+0x9d3): In function `pix_abs8x8_xy2_mmx2':

I've googled and the only promising post said to use an older version of gcc, I've tried both 3.4.3 and 3.2.3 with the same error.

If its a dependency problem, I cant figure out what it needs.

This is really annoying - I've been trying for days to get it installed now - any help much appreciated,

That's not a compiler error, that's a linker error.

Most likely either a name-mangling problem or
a plain type somewhere ;0 ... impossible to assess
from that output alone, though. We'd need to see
how it's invoked, and if THAT doesn't show any-
thing obvious then we'd need to see the code.

Dave, I am receiving the exact same errors.

Have you been able to rectify the problem?

Any help would be much appreciated.

Cheers.

If you're building librtk for player and gazebo then apparently (I'm just working through this myself) you don't need libavcodec which is causing the problems so use:

before you try to make.
