Preparation
This guide assumes that you have performed the steps in Building_OpenMoko_from_scratch
The commandline program
Store the following more or less standard hello world code in hello.c
#include <stdio.h>
int main()
{
printf ("Hello World\n");
return 0;
}
Compiling it the wrong way / easy
Assuming your current working directory is /home/moko,
and that you stored the code in /home/moko/hello.c
It should now be possible to compile the application using
./build/tmp/cross/arm-linux/bin/gcc -o hello hello.c
Testing it
Assuming you have followed Setting up USB connection and you have a working network concetion to either a qemu Neo or a real Neo.
scp hello root@192.168.0.202:/tmp/ ssh root@192.168.0.202 /tmp/hello
This sequence of commands ought to give you a nice Hello World, btw. the default root password is blank, just press return.
Why was it the wrong way?
OpenMoko uses [OpenEmbedded] and they use bitbake when building stuff
Compiling it using bitbake

Creating an ipkg package
