Install C Compiler on iPhone 4S [GCC Installer Script]

Like MSF Installer Script, i made little update to GCC Installer Script, i tested it and it works well. And it works the same as MSF Installer Script, we need to download the script via wget, make it executable and execute it. So before you start, make sure you have wget and aptitude installed(install them from Cydia), and we need ssh connection to install the script(or if you have MobileTerminal, you can install it directly from there).

To use script, connect to your device via SSH, and download the script by the following:

wget http://khalil_ounis.byethost4.com/gcc_installer_v3.sh

Make it executable by:

chmod +x gcc_installer_v3.sh

Executing the script

./gcc_installer_v3.sh

And that's it, all you have to do now is compile your c program, and use the following command before you execute it:

ldid -S YourProgramName

and execute your c program:

./YourProgramName

Hope i helped :), this is source code of the script:
