Well, the targets of most Csoundxo bindings don't exist in Fedora 14
Csound, which sadly doesn't comply with the full Midi spec, nor does it
have fixed-point opcode options which in Csoundxo run about 60% faster
on most processors (I've yet to test this on the 1.75's Armada 610).
Faster audio processing frees up more mips for graphic interaction --
such as in the XO Music Painter activity. The fork came about since my
original Csound was developed for larger machines (and has continued
that tradition), while Csoundxo is tailored to lower-power processors
which conform to the price-point of affordable XO education in really
disadvantaged countries. The TamTam suite isn't a good example since it
makes mostly trivial demands on either Csound.
I will continue trying to resolve the ALSA issues for Csoundxo, which
runs just fine on 386 installs.
Any help appreciated.

Great!
Can the bindings be packaged, and use the csound version available in
Fedora 14?
This bindings, can be used by example in the TamTam Suite?

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
