Description Tim-Philipp Müller 2010-01-26 23:52:19 UTC
When compiling against a core with debug logging disabled, I get these errors:

tpm@zingle:~/gst/no-debug/gst-plugins-good/gst/videomixer$ make
  CC    videomixer.o
  CC    blend.o
blend_mmx.h: Assembler messages:
blend_mmx.h:173: Error: can't encode register '%ah' in an instruction requiring REX prefix.
blend_mmx.h:174: Error: can't encode register '%ah' in an instruction requiring REX prefix.
blend_mmx.h:173: Error: can't encode register '%ah' in an instruction requiring REX prefix.

make: *** [libgstvideomixer_la-blend.lo] Error 1

Easy to reproduce even with a debuglog-enabled core by doing

 $ cd gst-plugins-good/gst/videomixer/
 $ make ERROR_CFLAGS='-DGST_DISABLE_GST_DEBUG'
