To compile software for the N810, you can use scratchbox, the cross-compile-environment for i386 machines. Or you can compile on the device itself.

  1. install openssh on the N810
  2. Find out what Maemo version you have. Choose Settings -> Control Panel -> About. If you get "Product maemo Linux based OS2008 Version:5.2008.43-7" this means Maemo 4.1, OS2008 and Diablo (more information on codenames).
  3. download wget from http://repository.maemo.org/pool/maemo4.1.2/free/w/wget/. Copy it to your computer and scp it to your N810.
  4. get glibc
    wget http://repository.maemo.org/pool/maemo4.1.2/free/g/glibc/libc6-dev_2.5.0-1osso10_armel.deb
  5. 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
  6. 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
  7. install everything
    dpkg -i gcc-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb libc6-dev_2.5.0-1osso10_armel.deb linux-kernel-headers/linux-kernel-headers_2.6.16.osso11-1_armel.deb
  8. do the usual test: 
/* main.c */
#include <stdio.h>
 
int main()
{ printf("hello world"); }
Nokia-N810-43-7:~# gcc-3.4 -o greeter main.c
Nokia-N810-43-7:~# ./greeter
hello worldNokia-N810-43-7:~#

C++

  1. Try to compile a C++ program: 
    // main.cpp
#include <iostream>
int main()
{
  std::cout << "hello C++" << std::endl;
}
    Nokia-N810-43-7:/media/mmc1# gcc-3.4 main.cpp
 <unknown> tried to exec cc1plus but failed (No such file or directory)
  2. download g++:
    wget http://repository.maemo.org/pool/maemo4.1.2/free/g/gcc-3.4/g++-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb
  3. download lib standard C++:
    wget http://repository.maemo.org/pool/maemo4.1.2/free/g/gcc-3.4/libstdc++6-dev_3.4.4cs2005q3.2-5.osso8_armel.deb
  4. install g++:
    dpkg -i libstdc++6-dev_3.4.4cs2005q3.2-5.osso8_armel.deb g++-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb
  5. try to compile main.cpp again: 
    gcc-3.4 main.cpp
/var/tmp/ccQkm9NS.o: In function `std::__verify_grouping...
  6. ok, but do it right: 
    gcc-3.4 -lstdc++ main.cpp
./a.out
hello C++
