Chuck gives segmentation fault

HI there.
I'm on 64 bit Ubuntu 9.04.
Chuck was in the 64 bit repo's so i installed it.
but when i try the tutorial on the chuck web i get:
(via rtaudio): no devices found for compiled audio APIs!
[chuck]: cannot initialize audio device (try using --silent/-s)

So then i try the -s option, but that gives the seg-fault.
My understanding was, there isn't a 64 bit version of chuck(yet).
But it was in the 64 bit repo's for Unbuntu 9, so i figured maybe someone compiled one
for 64 bit.
I'm assuming thats why I'm getting the seg-fault, but i couild be wrong

Has anyone been able to get chuck to work in 64 bit Linux?

chuck --probe gives:
chuck --probe
Enhanced3DNow! detected
SSE2 detected
[chuck]: found 1 device(s) ...
Enhanced3DNow! detected
SSE2 detected
[chuck]: ------( chuck -- dac1 )---------------
[chuck]: device name = "Jack Server"
[chuck]: probe [success] ...
[chuck]: # output channels = 6
[chuck]: # input channels = 2
[chuck]: # duplex Channels = 2
[chuck]: default device = YES
[chuck]: natively supported data formats:
[chuck]: 32-bit float
[chuck]: supported sample rates:
[chuck]: 48000 Hz
[chuck]:
[chuck]: ------( chuck -- 1 MIDI inputs )------
[chuck]: [0] : "Midi Through Port-0"
[chuck]:
[chuck]: ------( chuck -- 1 MIDI outputs )-----
[chuck]: [0] : "Midi Through Port-0"
[chuck]:

When i try to run a chuck script i get ;
Enhanced3DNow! detected
SSE2 detected
Enhanced3DNow! detected
SSE2 detected
Enhanced3DNow! detected
SSE2 detected
Segmentation fault

As far as i know it's impossible to get ChucK to compile and run on 64 bits Linux. I don't know who put it into the 64bit repositories but unless something spectacular happened that was likely a mistake.

Very sorry about this but I can't help it either.

Yeah, it really should be in the docs more clearly to avoid disappointments like yours.

It turns out that a 32-bit compiled chuck runs just fine on 64-bit Ubuntu.

I mounted the root file system for a 32-bit Ubuntu 9.04 and copied /mounted-root/usr/bin/chuck* into my ~/bin. The necessary 32 bit libraries, libasound2, et al., are contained in the standard ia32-libs package which was already installed on my machine.

does anybody know about 64 bit support? the http://chuck.cs.princeton.edu/release/ page says that they're working on it....

perhaps someone could unpack rec's post a bit for me... I don't quite follow. It sounds like hi booted to 32 bit linux, installed chuck, then ran it in 64 bit linux. is that right?

Sure, a little more unpacked. Though it sounds like you have it figured out.

A 64bit linux can run a 32bit application if you 1) install the application and 2) install the libraries it needs.

There are some trickier ways to accomplish 1) but I can never remember them, so I do it the easiest way for me and copy the chuck binary from a 32bit installation. To make sense of this you need to know that my laptop has a copy of XP, a 32bit version of Karmic Koala, and a 64bit version of Karmic Koala installed on it. For sake of argument, say that the XP is installed on /dev/sda1, the 32bit ubuntu on /dev/sda2, and the 64bit ubuntu on /dev/sda3. While running the 64bit ubuntu I can:
