Hello fellow Finkers,
sometime ago I made an updated package for the jack audio connection
kit
[1,2]. This was for Jack1. There is also Jack2, which is a
multiprocessor-capable backwards-compatible reimplementation [3].
Having
jack2 packaged is quite important because from my observations jack1
does not work on 10.6.
I believe it would not be possible to package jack2 for fink, as it
installs stuff into /Library/Frameworks and (more importantly) the
Jack.Router into /Library/Audio/Plug-Ins/HAL/. The rest is put into
/usr/local.
Am I right in assuming that it is not feasible to wrap such a program
into a fink package?
Anyway, I thought this would be a good idea to provide a system-jack
package [Attackment] that just looks for the existence of jackd
installed in /usr/local. However, I have got a few questions with this
approach:
- Apparently
Provides: jack, jack-shlibs, jack-dev
is not sufficient to peacefully co-exist with the exisiting
Jack1 jack.info. Fink still insists on installing jack1 to satisfy
a dependency on jack*. Would this be solved by renaming the old
jack package to e.g. 'jack1*' that also just "Provides" jack* ?
- This approach works well when freshly compiling programs from
source,
but for a binary distribution, wouldn't it be necessary to have two
versions of each program, one linked against jack and one against
system-jack? How is this usually handled by other fink packages?
One solution would be to create different versions of each program
depending on jack, like with kde-x11 and kde-mac, but this seems like
unecessary duplication of work. What's best practice in this case?
thanks,
Adrian

Good Day Adrian
The latter release of JackOSX seems to be incompatible with coreaudio.
If you excuse the pun) Jack seems to hijack CoreAudio. If JackOSX
remains installed and I run `fluidsynth -a
coreaudio...' the jackd server daemon is started and audio is rendered.
The only way I can run fluidsynth with coreaudio is to first remove
and trash my Jack installation and then build fluidsynth without Jack.
Just my $0.02.
