nios2-linux-gcc is a symbolic link (similar to short cut in Windows) , pointed to the real nios2-linux-uclibc-gcc.

The default apps library is uClibc&#39;s libc, so you don&#39;t need -lc .

If you use math, you need -lm .

If you use pthread, you need -lpthread .

If you use crypt, you need -lcrypt .

.....etc.

You will need those include headers, too.

The order of librarys is important, the linker will search only one pass by default.

The default include dir search path is staging_dir/include .

The default library search path is staging_dir/lib .
