Compiling on the N810

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 gcc

   wget http://repository.maemo.org/pool/maemo4.1.2/free/g/gcc-3.4/gcc-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb

5. get cpp

   wget http://repository.maemo.org/pool/maemo4.1.2/free/g/gcc-3.4/cpp-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb

6. get binutils

   wget http://repository.maemo.org/pool/maemo4.1.2/free/b/binutils/binutils_2.16.91cs2005q3.2-5.osso1_armel.deb

7. get glibc

   wget http://repository.maemo.org/pool/maemo4.1.2/free/g/glibc/libc6-dev_2.5.0-1osso10_armel.deb

8. 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

9. get libgcc

7. do the usual test:

<source lang="c"> /* main.c */

1. include <stdio.h>

int main() { printf("hello world"); } </source>

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: <source lang="cpp"> // main.cpp
   1. include <iostream>
   int main() { std::cout << "hello C++" << std::endl; } </source>

   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++:

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

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++
