I got the SYSV IPC patch for uC-libc from the download site, but it has only support for shm and sem, no msg at all.
(Further, I applied the patch against Devboard_Lx latest distr, and it found many errors too...)
I tried to hack around, mimicking yout patch for msg calls, but the runtime answer always "Operation not implemented"
Where's the problem?
When a new full patch?
