Hi. I'm using AMD64 at work since some months now, and really would like to make my next private system AMD64. However, since I am a dedicated SuperCollider user, I will need to invent some hackery to make SC run on AMD64. Here is the story: SuperCollider is due to some strange usage of pointers unable to run on 64-bit architectures. So, since AMD64 is 32-bit compatible, I thought this problem should be circumventable in some form. I first tried to install a ia32 chroot with the 32bit supercollider binaries in it (all installed via apt-get). Now, the first approach would be to run JACK *and* supercollider in the 32-bit chroot. amd64:/# jackd -vd alsa getting driver descriptor from /usr/lib/libjack0.80.0-0/jack_alsa.so getting driver descriptor from /usr/lib/libjack0.80.0-0/jack_dummy.so getting driver descriptor from /usr/lib/libjack0.80.0-0/jack_oss.so jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details registered builtin port type 32 bit float mono audio running with uid=0 and euid=0, will not try to use capabilites loading driver .. new client: alsa_pcm, id = 1 type 1 @ 0x80577d8 fd = -1 creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit ALSA: Cannot open PCM device alsa_pcm for playback. Falling back to capture-only mode cannot load driver module alsa OK, so there seems to be some incompatibility which prevents 32bit JACK from using ALSA. The other possibility, although even less likely to work, would be to run jackd in 64bit, and only the jack client of supercollider inside the chroot: amd64:/# jackd -d alsa jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead So JACK is running fine in 64-bit mode, no problems to open ALSA... Now for the fun part, run inside the ia342 chroot: amd64:~# scsynth Using Altivec: no could not initialize audio. amd64:~# So now SuperCollider doesn't find the 64bit instance of JACK. I am sort of out of ideas here. Can anyone suggest some course of action which could perhaps work? Being able to run SuperCollider is really the last showstopper for me, without that problem, I'd already have ordered my new box... -- CYa, Mario
