[xine-user] xine CVS fails during memcpy benchmark - Illegal Inst.

[Kevin B. <Co...@co...>]

I pulled xine from CVS last night.  I'm able to build successfully, but
when I run it, xine fails with an Illegal Instruction:

Benchmarking memcpy methods (smaller is better):

Illegal instruction

---------------------------

I did a standard make, gdb gives the following bt:

System is SuSE 7.1 updated to kernel 2.4.9 ( w/MOSIX clustering patch)

gcc 2.95.2, AMD K6-2 3D processor

I notice that the default compiler options use -mcpu=pentium on my
system.  Setting XINE_BUILD=k6-pc-linux-gnu causes the use of -mcpu=k6
with no difference (xine still fails).  Is there a way to set '-march'
with the cvscompile.sh script?  Or to fall back from -O3 to -O2?  I
tried a couple attempts but was unsuccessful.  Thanks,
