Re: [LAU] building csound from source - OOps/remote.c:70: error: storage size of 'ifr' isn't known

I don't think this is my problem, but I don't know why io.h is not found:

Checking for C header file io.h... (cached) no

does that mean that it's not cached, or it's not found? It's in my
/usr/include/sys directory, and other C headers are found.

Is this normal? Or not?
