program does compile but when I run it I get nothing as output. I did tried
mips-linux-gnu-gcc and
from
Realtek SDK but its same deal does not print hello world to console.
I also tried changing
to
and
to
but again its same deal I dont get anything printed to console. As emulator I used qemu-mips-static and my mips box (its actually MIPS router)
