I'm having problems with the current stable version of jackd.
This version recentlywent 'stable' and I now get
| Code: |
$ jackd -d alsa
jackd 0.99.0

Illegal instruction

As opposed to

Under 0.98.1 - I reverted back to 0.98.1 in order to have a working system, I have a SB Live with a seemingly OK ALSA. It also seems like the ebuilt forces various compile flags (.e.g -ffast-math -funroll-loops -fprefetch-loop-arrays -O3) although it doesn't look like this has changed since 0.98.1 so I doubt it is the problem. |

Well something is wrong at the compiler level. I can't imagine any other
way that you can generate an illegal instruction.
Try
| Code: | | # CFLAGS="" emerge jack-audio-connection-kit |
to rule this out. |

| It appears it doesn't like the march=althon - I edited the ebuild to remove that flag and now it runs. Of course now ardour won't build (looks like it's due to having 2.6 headers), but other than that..... |

Oh, 0.99 is still broken for me - I was just being optimistic and hadn't given it a real test.
Interestingly I downloaded the 0.99 sources and installed form outside portage -and it works just fine (yes really tested it this time - up to and including recording through Ardour)- so I've no idea what's up with that.
I'll try the athlon-tbird march and see if that helps.
Thanks. |

| No, athlon-tbird doesn't help - it's definitely something in the ebuild though as a build from tgz works just fine. |

Ok, I'll try the ebuild on my tbird later for you. But the compile options
in the source may not enable optimizations that are creating the illegal
instructions. |

Try this boot line, and see if that helps:
jackd -d alsa -p2048 -r 48000 -S
-S forces it to try 16 bits first.
That line gives me:
wrc@mymachine ~ $ jackd -d alsa -p2048 -r 48000 -S
jackd 0.99.0

with no xruns.
This is with an Athlon-xp 1700, so you might need to adjust it a bit. man:jackd in a Konqueror browser window url address line explains all the options on a nice html page instead of the konsole, and what they do.
Do you get any xruns?

Use flags are:
| Code: |
Calculating dependencies ...done!
[ebuild R ] media-sound/jack-audio-connection-kit-0.99.0 +alsa (-altivec) +caps -debug -doc -jack-tmpfs +oss -portaudio 0 kB
|
BTW it's not really installed, I let it install and ended up installing from the tgz over the top of the portage installed files.
make.conf is:
| Code: |
CFLAGS="-march=athlon-tbird -O3 -pipe"
|
It works perfectly with a jackd built 'by hand' from source (i.e. configure, make, make install), 0.99 definitely helps with some of the problems I was having with NPTL (which was a documented issue in previous versions of jack).
In answer to the other comment, yes I do get xruns - but I think that is more due to being a slower cpu, they only really occur at times of high cpu usage, or when really piling on the effects plugins. |

You want that jack-tmpfs flag if /tmp is mounted on a jounrlaing FS
like reiser or ext3.
Still haven't had a chance to try on my tbird. |
