Some yes, some no. Many applications will compile "as is".
If an application uses some of the system call support that
uClinux doesn't support (fork, sbrk for example) then the app
will need to be modified. Occasionally you will get an app
that uses something from glibc that is not implemented in
uClibc too, and that may also required a change.
