Can I have some of that idle RAM? I suppose that 2x-4x the original setting might possibly be enough, probably don't need 256x. I'll wait to see if the list suggests any heuristics for picking a good number. > If it is decided to switch out libc, I may be able to help a bit.

However, the dietlibc package's libm that comes with Fedora contains symbols for sinh and asinh but no sin. The example I wrote to test the math functions runs fine linked with glibc but won't link against dietlibc.

Oh cool, I used to use LEAF over 10 years ago! Firewall on a floppy. I'm just getting into it now, but my guess from looking at configure.in is that dietlibc is only being used for libm in the RT-Linux kernel modules. I suppose that means that everything else in rtapi is already available in the kernel, and the ulapi and user land apps are probably linked against glibc. If that's true, then it's probably not trivial to port everything to dietlibc. My hope for getting rtapi/hal/rtapi_app linked against dietlibc was to reduce latency, but that may be a project for later. Now it's time to give this thing a whirl! Thanks again for everyone's ideas, encouragement and hard work.
