193.175.8.58: corrected dpkg line

To compile software for the [[Nokia N810|N810]], you can [[:Category:Scratchbox|use scratchbox]], the cross-compile-environment for i386 machines. Or you can compile on the device itself.

# [[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 ([[Codenames|more information on codenames]]).
# 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.

# do the usual test:

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

<ol>
<li>Try to compile a C++ program:
<source lang="cpp">
// main.cpp
#include <iostream>
int main()
{
std::cout << "hello C++" << std::endl;
}
</source>
<pre>
Nokia-N810-43-7:/media/mmc1# gcc-3.4 main.cpp
<unknown> tried to exec cc1plus but failed (No such file or directory)
</pre>
</li>
<li>download g++:<pre>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</pre>

</li>
<li>
try to compile <code>main.cpp</code> again:
<pre>
gcc-3.4 main.cpp
/var/tmp/ccQkm9NS.o: In function `std::__verify_grouping...
</pre>
</li>
<li>
ok, but do it right:
<pre>
gcc-3.4 -lstdc++ main.cpp
./a.out
hello C++
</pre>
</li>
</ol>
