CPU extensions are not detected

[Carlos Eduardo Moreira dos Santos]

Binary package hint: x264

Expected output (intel E3300):
x264 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 Cache64
Current output:
x264 [info]: using cpu capabilities: none!

Is it possible to remove "--disabe-asm" from configure flags?

[Reinhard Tartler (siretart)]

seems that the kernel doesn't detect the processors SSE2 capabilities.

please provide the output of the following commands:

# to check what version of the libx264.so library is picked up
$ ldd /usr/bin/x264

# check cpu capabilities
$ cat /proc/cpuinfo

Recompiling x264 from git worked for me. Requested information:

yes, but makes the requested output worthless. The package ships two
copies of libx264.so, one compiled with sse2 support and one without. we
now need to find out why it's picking up the wrong copy on your system.

you've now overwritten the x264 binary with a copy that statically links
the correct copy.

No, the output is from /usr/bin/x264 and the working x264 compiled by myself is in another path.

[Carlos Eduardo Moreira dos Santos (cemsbr)]

Another thing to check: was yasm installed before compiling repository binaries?

Using 2:0.98.1653+git88b90d9-3 in Maverick (32 bits) I don't have this problem on a C2Q 9550. I didn't see Carlos version anywhere on the thread, so sorry if it's there but I missed it.

[Reinhard Tartler (siretart)]

Carlos, can you please state the exact package version that is causing problems to you please?

[Carlos Eduardo Moreira dos Santos (cemsbr)]

$ /usr/bin/x264 --version
x264 0.98.1653 Ubuntu_2:0.98.1653+git88b90d9-3
built on Oct 5 2010, gcc: 4.4.5

[Carlos Eduardo Moreira dos Santos (cemsbr)]

This error can be reproduced in 3 machines, all with intel processors. The workaround (compiling x264) works in all of them. Let me know if you need more data.
