I can compile C files, but how can i execute them?
I tried:

Error is: Permission denied
So i tried:
$ sudo ./test
but this doesn't work too
sudo gainroot
chmod 777 test
./test

EDIT: chmod only needs to be done once.

How safe is this considered to be. Any issues with
- disk space with future firmwares
- overwriting any existing libraries thus causing incompatibilies/stability. I'm assuming its not just the gcc binary that gets downloaded, but a bunch of dependencies too

chmod seams to be corrupt.

I assume you are working somewhere below the MyDocs directory. Go into /home/user and create there a new folder if you wish. The MyDocs folder is a vfat partition and does not allow executables. chmod will fail there because it's not a linux partition.

to have only gcc, I edited sources.list and did apt-get install gcc

but it can't find stdio.h and I also get a link error of crt1.o no such file.

What other dependencies are needed? how much more is this going to bloat to?

If you want a full development environment, probably quite a bit.

I run an SDK in a chroot. Qole is hosting an image here.
You can install the easy-chroot scripts and run it without having to worry about bloating your rootfs or installing things on the device that might cause problems with busybox.

This is awesome, just got it set up on my n900. Good work chaps/chapettes! Just compiled my own small game directly on the phone.

A few questions. Assume I have an empty MicroSDHC card, should I prepare it with ext3 as told earlier in this thread and then somehow mount the above ext2 image on it or? Could you give some short guidelines how you mount the image on the card so that the development can be made there and which easy-chroot scripts you then run to use it?

Thanks for any help!
