Why are you not using dynamic libc library but static version?
Note that for only simple programs you dont need to install/copy any libraries to system. Dynamic libc library is part of Maemo5.

And if you do not want to install libraries to rootfs, you can use param -L<dir> which specify directory where are neede libraries stored (like -I for include)

If you have still problem, can you send me source of your program?
