Bug 76383 – jack-audio-connection-kit-0.99.0.ebuild failed on a Intel Pentium II

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Ewan 2005-01-02 00:17:24 UTC]

When using jack-audio-connection-kit-0.99.0.ebuild on an Pentium II (Deschutes), it creates a binary that fails with an 'Illegal Instruction'.  Found out it was to do with the --enable-optimize flag in the ebuild, that needed taking out.  I assumed that it was jack's fault, and not the ebuild as the configure script should detect the cpu info, but hey I got told to fill out a big report so here it is.

Reproducible: Always
Steps to Reproduce:
1. emerge jack-audio-connection-kit on a Pentium II Deschutes
2. run the jackd binary
3. And Bingo, Illegal Instruction

Actual Results:  
The jackd fails to run, with no other output apart from 'Illegal Instruction'

Expected Results:  
Detected I was using a really crap cpu and not done the --enable-optimize flag

I'll have a look at fixes for this, I've not forgotten about it. Bear with me :)

can you attach a copy of the binary and the output of /proc/cpuinfo please. thanks

please reopen when you have the requested information. thanks

Created attachment 48358 [details]
Binary created on a PII Deschutes

Works if you run it with no arg's ie so it spits out the help info

Crashes if you try it with -d oss or -d dummy.

cat /proc/cpuinfo follows:

the binary you attached has SSE intructions in it but your CPU doesn't support them. I'll look at patching the configure script and sending upstream. Ta for reporting, should be fixed shortly.

[Comment 7 rob holland (RETIRED) 2005-01-25 03:55:27 UTC]

hmm. can't see why this would happen based on the configure code. can you please send me a config.log for ./configure from jack. thanks.

reopen when/if you have time to progress this.
