HOWTO: C/C++ compiling on the unit itself.
 

[Last update: 21 July 07]

Here's how to do C/C++ compiling on the unit itself.

What you need:

gainroot
xterm (apt-get install osso-xterm)
wget (Download from: http://maemo.org/downloads/product/wget/)


Instructions:

First, fire up your xterm and type the following lines

After you have done so, you will now be able to compile with the command

**Do note that you will get a permission error if you try to compile your source files located on a vfat storage.

These steps are put together by a linux beginner who has no idea what he is doing. It didn't screw up my installation, but your mileage may vary.

Re: HOWTO: C/C++ compiling on the unit itself.
 

I'm not sure if anyone actually cares about this thread, but anyway, some updates.

I have verified that the SciTE editor works fine at compiling c++ programs.

However, to use the compile button on Scite editor, you need to make type the following commands into your xterm.

Using the build command will however require 'make'.

Re: HOWTO: C/C++ compiling on the unit itself.
 

Do you by any chance know where a copy of 'make' exists for the device?

Re: HOWTO: C/C++ compiling on the unit itself.
 

Here it is.


This should get it installed IF there are no dependencies error. No time to check that now, but i will do that soon.

I'm watching and interested :)

Re: HOWTO: C/C++ compiling on the unit itself.
 

No dependency errors. Thanks.

Re: HOWTO: C/C++ compiling on the unit itself.
 

Doesn't seem to work :(

Re: HOWTO: C/C++ compiling on the unit itself.
 

i've successfully install gcc and osso/hildon library before the flash with the new os. But it's take too many place (100Mo).

Re: HOWTO: C/C++ compiling on the unit itself.
 

On the new OS? I have yet to tried it install it on the new OS yet, but i'll try it out this weekend.

edit: realised i left out wget-ing one of the files in my instructions. i have updated it, so try again if you will.

edit: seems like these instructions are not useful on the latest firmware ('chinook').

Re: HOWTO: C/C++ compiling on the unit itself.
 

On a uncompressed ext 2 filesystem, the whole installation takes up 50mb on my system. If you are using the jffs2 filesystem, it should be much lesser.

Re: HOWTO: C/C++ compiling on the unit itself.
 

can anyone supply a hint or fix for the binutils ld not finding shared libraries?

?

thanks,

rob.

edit:

the problem is with libs that do not end in .so :

Re: HOWTO: C/C++ compiling on the unit itself.
 

I had some errors when i was trying to install g++. A file was missed in the wget step and another one that was downloaded wasn't installed.
Here is the modified script that worked for me.

I hope i haven't missed anything.

Re: HOWTO: C/C++ compiling on the unit itself.
 

Thanks rob and i.rachita for the update/fix!

Anyway rob, does that mean that libraries that end in .so will work now? Is it only libcrypto that is affected or are there other libraries that don't end in .so too?

Re: HOWTO: C/C++ compiling on the unit itself.
 

Hi,

This looks brilliant, and i'll try it out soon. Should i consider converting/creating a new partition (efs and jffs2 are mentioned) on my internal memory card for this?

Re: HOWTO: C/C++ compiling on the unit itself.
 

That's really up to you, it takes up 50mb on my uncompressed filesystem. On a jffs2 partition, it should take up a lot lesser.

Re: HOWTO: C/C++ compiling on the unit itself.
 

Great post, thanks for the info!

Much appreciated.

Re: HOWTO: C/C++ compiling on the unit itself.
 

Agreed. Just followed a modified version to get gcc working on an N800 in OS2008 and it works a treat. Portable c++ development here I come.

Re: HOWTO: C/C++ compiling on the unit itself.
 

Hi,

Then, it's possible to compile a c or c++ app source like in any other linux dist?

I'm thinking that if we have the make utilitie and c/c++ libs, it's possible to make ./configure make make install/or buid package with dpkg utilitie, is it true?

sorry if this is an stupid question, i'm new with the IT, and escuse my poor english.

I would love to see a complete replacement for Scratchbox that runs on the tablet. Plus Glade.

This is way beyond my capabilities to create but I would cheer heartily from the sidelines.;)

Re: HOWTO: C/C++ compiling on the unit itself.
 

This is so cool. As I read a PDF about C++ using the Evince Document reader, I can try out the examples using SciTE.

I did this today, and had to update all of the WGETs to reflect the latest OS. As well the install for G++ had to be done simultaneously with the libc++-dev. Here is what I did:

wget http://repository.maemo.org/pool/dia...sso8_armel.deb
wget http://repository.maemo.org/pool/dia...sso8_armel.deb
wget http://repository.maemo.org/pool/dia...sso8_armel.deb
wget http://repository.maemo.org/pool/dia...sso8_armel.deb
wget http://repository.maemo.org/pool/dia...sso8_armel.deb
wget http://repository.maemo.org/pool/dia...so10_armel.deb
wget http://repository.maemo.org/pool/dia...so10_armel.deb
wget http://repository.maemo.org/pool/mae...11-1_armel.deb
wget http://repository.maemo.org/pool/dia...sso1_armel.deb

dpkg -i binutils_2.16.91cs2005q3.2-5.osso1_armel.deb
dpkg -i linux-kernel-headers_2.6.16.osso11-1_armel.deb
dpkg -i libc6_2.5.0-1osso10_armel.deb
dpkg -i libc6-dev_2.5.0-1osso10_armel.deb
dpkg -i gcc-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb
dpkg -i cpp-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb
dpkg -i libstdc\+\+6_3.4.4cs2005q3.2-5.osso8_armel.deb
dpkg -i libstdc\+\+6-dev_3.4.4cs2005q3.2-5.osso8_armel.deb g++-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb

apt-get -f install

apt-get install make

cd /usr/bin
ln -s g\+\+\-3.4 g\+\+

After this I also downloaded the source for grep-2.4 to replace the busybox grep. This helps compiling many other packages:
wget http://mirror.csclub.uwaterloo.ca/gn...rep-2.4.tar.gz
gunzip -dc grep-2.4.tar.gz | tar -xv
cd grep-2.4/
./configure
make
make install
rm /bin/grep
ln -s /usr/local/bin/grep /bin/grep

Re: HOWTO: C/C++ compiling on the unit itself.
 

Just one note; to get grep compiled I needed to use

./configure --host=arm-linux-gnueabi

It couldn't detect what platform it was on.
Also, you can also create links to egrep and fgrep as compiling this packages will give you all three egrep/fgrep/grep.

Nathan.
P.S. Is their some environmental variable I do need to set, so I do not have to use the --host, anyone know?

please help me compiling this app:

thanks!:)

It's not a simple task we have to port x86 to armel and that needs time and effort.

Re: HOWTO: C/C++ compiling on the unit itself.
 

I'm getting this error :

http://www.internettablettalk.com/fo...ight=libc6-dev

Any ideas?

Re: HOWTO: C/C++ compiling on the unit itself.
 

Looks like the lib6c version on the tablet isn't high enough for the program you want to use. You might want to try an older version of what you're wanting, as it probably has lower dependencies.

where i can download gcc for C++,arm programming for my n900
