Here I prepare articles for this wiki to come.

Compiling on the N810

wget http://repository.maemo.org/pool/maemo4.1.2/free/g/glibc/libc6-dev_2.5.0-1osso10_armel.deb
  • get linux kernel headers
wget http://repository.maemo.org/pool/maemo4.1.2/free/l/linux-kernel-headers/linux-kernel-headers_2.6.16.osso11-1_armel.deb
  • get libgcc
wget http://repository.maemo.org/pool/maemo4.1.2/free/g/gcc-3.4/libgcc1_3.4.4cs2005q3.2-5.osso8_armel.deb
  • install everything
dpkg -i gcc-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb
  • do the usual test
Nokia-N810-43-7:~# cat main.c
#include <stdio.h>

int main()
{ printf("hello world"); }

Nokia-N810-43-7:~# gcc-3.4 -o greeter main.c
