These look just fine. Even stranger.

That's ok too.

Just put:

#include <stdio.h>
int main(int argc, char **argv) { printf("Hello, world!\n"); return 0; }

into a hello.c, start sb2 and run:

gcc -o hello hello.c

after which:

./hello

It should say: Hello, world!

Oh, and please update your sbox2 first, I fixed some stuff ;)
Simply git pull from the repo, ./autogen.sh && ./configure etc. etc.
