The king of C compiler, the GNU GCC, is installed by default on the Arietta microSD so you can compile directly on the board your sources.
To try it save the following example on a microSD folder with the name hello.c.
#include "stdio.h" int main(void) { printf("Hello world !\n"); return 0; }
Compile it typing:
~# gcc hello.c -o hello
Then lauch it typing:
~# ./hello Hello world !
