Dear All, As Mark noted, chuck compiles but crashes on amd64 running gentoo/ALSA. Mark and I have already looked into this and have come up with the following so far: Most likely, this is due to data type width disparity for the 64-bit system, for example, here are the type width on amd64/gcc on Mark's machine: # ./platform sizeof(char): 1 sizeof(short): 2 sizeof(long): 8 sizeof(int): 4 sizeof(unsigned): 4 sizeof(float): 4 sizeof(double): 8 sizeof(void *): 8 endian: SMALL which differs from most 32 bit machine: # ./platform sizeof(char): 1 sizeof(short): 2 sizeof(long): 4 sizeof(int): 4 sizeof(unsigned): 4 sizeof(float): 4 sizeof(double): 8 sizeof(void *): 4 So... 1) Anyone else here have experience/access to amd64/linux 2) Mark, is there anyway I can ssh into your machine and test there? 3) We should look into gcc on amd64 to see there is a 32-bit compatibility flag - that would solve a lot of things. 4) Any other thoughts/ideas? Best, Ge!

I "suspect" the problem is ChucKs interface to ALSA.
Most likely, this is due to data type width disparity for the 64-bit system, for example, here are the type width on amd64/gcc on Mark's machine:
Summary: difference being longs and pointers on x86_64 are 8 bytes instead of 4 otherwise the same.
1) Anyone else here have experience/access to amd64/linux 2) Mark, is there anyway I can ssh into your machine and test there?
Sure, just pop me an email offlist and I'll reply with id/pw.
3) We should look into gcc on amd64 to see there is a 32-bit compatibility flag - that would solve a lot of things.
But not the core problem.
4) Any other thoughts/ideas?
Misc suggestion; the ability to write out a wav file would be very handy. This would also provide the ability to completely separate the core code from any platforms audio sub-systems so the "output" only goes to the much simpler file system interface. --markc
