Compiling on the N810

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, 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++
