hi,
what should I care in my kernel structure, so that porting gnu libc will be easy.
you know if gnu libc are ported, then the most application will be easy to port it.

Except for the OS dependant syscalls (ie video, keyboard etc.) the libc is independant.
If you want to make implementing syscalls easy then try to keep a standard for all the calls:-
Code: Select all
void read(int start, char *buffer, int size);
Or something which can cover all device calls fairly well

This particular standard is called POSIX. If you implement it then your OS will be compatible with most Unixes.

Free POSIX specifications are hard to come by, since you're supposed to buy a copy.

Linux is POSIX compatible. Maybe it's source can tell something?

You're likely to find more information from the Linux man pages than the source. The Linux man pages act as a useful Posix reference (at least where Linux is compliant) whereas the sources are more likely to confuse most people.
