Here I prepare articles for this wiki to come.
Compiling on the N810
- install openssh on the N810
- 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. So you have maemo, os2008 and diablo (more info).
- 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.
- get glibc
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 libc6-dev_2.5.0-1osso10_armel.deb linux-kernel-headers/linux-kernel-headers_2.6.16.osso11-1_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
Nokia-N810-43-7:~# ./greeter
hello worldNokia-N810-43-7:~#
C++
- Try to compile a C++ program
Nokia-N810-43-7:/media/mmc1# cat 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)
- 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
- 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
- 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
- try to compile main.cpp again
gcc-3.4 main.cpp /var/tmp/ccQkm9NS.o: In function `std::__verify_grouping...
- ok, but do it right
gcc-3.4 -lstdc++ main.cpp ./a.out hello C++
Compiling software with automake
Does not work.
Compiling Qt software
Nokia-N810-43-7:~# cat /etc/apt/sources.list deb http://repository.maemo.org/extras/ diablo free deb-src http://repository.maemo.org/extras/ diablo free Nokia-N810-43-7:~# apt-get install libqtcore4

# cat qttest2.cpp
#include <QApplication>
#include <QPushButton>
int main(int argc, char ** argv)
{
QApplication qa(argc,argv);
QPushButton* qp=new QPushButton("hello world");
qp->show();
return qa.exec();
