I'm the original author of Csound, and more recently of CsoundXO made especially for the OLPC XO laptop. Both are C-language programs, the latter with a set of fast Python bindings for development of special interactive XO Activities (applications).

To compile csoundxo on the latest XO 1.75 ARM machine I did the following (native):

    yum install gcc
    yum install alsa-lib-devel-1.0.24-1.fc14.armv5tel.rpm
gcc -o csoundxo -I/usr/include -I./include -D_POSIX_C_SOURCE -L/usr/lib -lasound -lm ./csrc/*.c

The install appears to be missing an alsa component, including I suspect a PulseAudio plugin config, which then fails to resolve references to things like
    snd_pcm_sw_params_t

Where do I find the right code for this ARM machine?

Thx
