The original loader.c doesn't compile, due to O_ASYNC (and other stuff) -
worked around in the patch for Windows folks. No help there ...
I did some poking and experimentation, and here's a tad more info:
- The "Invalid argument" error happens the very first time keepaliveSend() is
called.
- Using the -v verbose switch yieldsd nothing more, since dll dies before it
really gets off the ground. The IR tower LED never comes on.
- The fd returned by rcxFD() within keepaliveSend() is right and proper (4),
the same as the fd used by the RCX comm stuff in firmdl3 (which basically
works on my system).
Any further ideas?
