[How-To] Install gcc compiler in iPhone / iPod Touch for firmware 1.1.x

You can now install open toolchain headers and gcc compiler for native application in your iPhone/iPod Touch. Although compiling in iPhone/iPod Touch is slow, it is stable and very native.

If you have ever build the cross compiler from sources in Mac or PC before, you will be happy to see this working development environment in your iPhone/iPod Touch within 10 minutes or so.

You can follow these steps to have the working gnu gcc compiler, gnu make and the open toolchain header files for 1.1.x :

Do steps 1 to 3 if you haven't installed Cydia in your iPhone/iPod Touch 1.1.x

1. Set your iPhone/iPod Auto-Lock to "Never"
2. Goto Installer and install the package Called Cydia Installer (version 1.0). It will take about 5 minutes to download and install, so you should have connected your iPhone/iPod to Wifi
3. After installation of Cydia, iPhone/iPod will reboot and you will find a new icon "Cydia" in your Home Screen. Start "Cydia" and it will tell you to update Critical Packages. Follow the instructions to "Update All"
4. After update of Critical Packages in Cydia, install the following 3 packages
GNU C Compiler
Make
iPhone 1.1.1 Headers
5. Then you will have the iPhone gcc compiler in your iPhone/iPod now. You can use Mac Terminal or Windows putty to access the terminal of iPhone/iPod via SSH and start building your application.

To test the installation, you may want to try some HelloWorld example, and here is the attachment that you can try

copy and unzip it to your iPhone / IPod Touch

then

Code:

cd HelloWorld
make install
./restart

Then you will have a new native app HelloWorld in Home Screen.

To uninstall this HelloWorld

Code:

cd HelloWorld
make uninstall

P.S. There is a nano editor, if you really want to do source editing in Mobile Terminal
You can also build app in iPhone /iPod Touch in Mobile Terminal as well, see this


Enjoy!

The gcc in iPhone procedure is updated here for the pwned iPhone firmware 2.0/2.0.1

If you install iPhone GCC, it is important to set root partition to about 700M in pwnage, if you set it too small your will get into trouble whenever there is an upgrade of GCC, as some of the libexec cannot be symlink to second partition.

You have to install the following packages in Cydia

• GNU C Compiler
• iPhone 2.0 Toolchain
• Make
• Link Indentity Editor
• wget (... in order to download the following sample in iPhone)
• zip (... in order to unzip the following sample in iPhone)

then download the following zip file in your iPhone to test build your iPhone toolchain app

Code:

wget http://www.iphone.org.hk/attach/38270-HelloWorld2.zip
unzip 38270-HelloWorld2.zip

Code:

cd HelloWorld
make 
make install

Restart your springboard, then you will have the HelloWorld app on your springboard

To uninstall HelloWorld.app

Code:

cd HelloWorld 
make uninstall

I saw that this post was on the first page and said "huh, some poor sap must've searched like I did and posted in this old thread out of last hope." Glad it's not the case. Thank you very much javacom!

iPhone GNU C compiler is a great development tool, we have to make good use from it.

iPhone 2.0 Toolchain is a compatibility toolchain so wouldn't it be better to have the real deal, the headers from the 2.0 Apple SDK, and possibily more headers that enable more features that the Apple SDK intentionally left out ?
And obviously the other question rises, how to get the headers from the Apple SDK working ?

There was an iPhone 2.0 header package in Cydia when I first pwned to 2.0. But it isn't there anymore, I guess it was removed.

But you can still scp your sdk headers from Mac to iPhone Framework folders and also class-dump the private frameworks to get the headers.

[How-To] copy SDK headers to iPhone and compile SDK applications in iPhone

Here is the procedure on how to copy the iPhone SDK headers from your mac to iPhone GCC to have a SDK development environment in iPhone

If you use Linux / Microsoft Windows, see this on how to get the header files from the SDK
http://www.theiphonewiki.com/wiki/in...=Toolchain_2.0

Use this shell script in Mac Terminal to copy the installed SDK header files to iPhone directly
and you have to change IPHONEIP for your actual iPhone IP address
The script will install the sdk header files to /var/sdk of iPhone

Code:

#!/bin/sh
IPHONEIP=10.0.2.2
sdkroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Library/Frameworks
sdkframeworks[1]=$sdkroot/AddressBook.framework/Headers/*
sdkframeworks[2]=$sdkroot/AddressBookUI.framework/Headers/*
sdkframeworks[3]=$sdkroot/AudioToolbox.framework/Headers/*
sdkframeworks[4]=$sdkroot/AudioUnit.framework/Headers/*
sdkframeworks[5]=$sdkroot/CFNetwork.framework/Headers/*
sdkframeworks[6]=$sdkroot/CoreAudio.framework/Headers/*
sdkframeworks[7]=$sdkroot/CoreFoundation.framework/Headers/*
sdkframeworks[8]=$sdkroot/CoreGraphics.framework/Headers/*
sdkframeworks[9]=$sdkroot/CoreLocation.framework/Headers/*
sdkframeworks[10]=$sdkroot/Foundation.framework/Headers/*
sdkframeworks[11]=$sdkroot/MediaPlayer.framework/Headers/*
sdkframeworks[12]=$sdkroot/OpenAL.framework/Headers/*
sdkframeworks[13]=$sdkroot/OpenGLES.framework/Headers/*
sdkframeworks[14]=$sdkroot/QuartzCore.framework/Headers/*
sdkframeworks[15]=$sdkroot/Security.framework/Headers/*
sdkframeworks[16]=$sdkroot/SystemConfiguration.framework/Headers/*
sdkframeworks[17]=$sdkroot/UIKit.framework/Headers/*
sdkframeworks[18]=/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.0.sdk/System/Library/Frameworks/IOKit.framework/Headers/*
iphonesdkroot=/var/sdk
iphoneframeworksroot=$iphonesdkroot/include

iphoneframeworks[7]=$iphoneframeworksroot/CoreFoundation/
iphoneframeworks[8]=$iphoneframeworksroot/CoreGraphics/
iphoneframeworks[9]=$iphoneframeworksroot/CoreLocation/
iphoneframeworks[10]=$iphoneframeworksroot/Foundation/

ssh root@$IPHONEIP "mkdir -p $iphoneframeworksroot"
scp -r /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/usr/include root@$IPHONEIP:$iphonesdkroot
scp -r /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/usr/lib root@$IPHONEIP:$iphonesdkroot

for index in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
do
  echo "copying ${sdkframeworks[index]} to ${iphoneframeworks[index]}"
  ssh root@$IPHONEIP "mkdir -p ${iphoneframeworks[index]}"
  scp -r ${sdkframeworks[index]} root@$IPHONEIP:${iphoneframeworks[index]}
done

In order to avoid typing the password using ssh, you can install the ssh public key of your Mac to your iPhone using the following method

(a) keygen in Mac terminal and type (if you haven't generated it before)

Code:

ssh-keygen -t rsa

(b) create .ssh directory in iPhone (assume ip address of iPhone is 10.0.2.2) and in Mac terminal and type

Code:

ssh root@10.0.2.2 'mkdir -p .ssh'

then enter iPhone root password (alpine)

(c) copy mac public key to iPhone, and in Mac Terminal type

Code:

cat ~/.ssh/id_rsa.pub | ssh root@10.0.2.2 'cat >> .ssh/authorized_keys'

then enter iPhone root password (alpine)

(d) Edit the file /etc/ssh/sshd_config in iPhone

change these

Code:

#StrictModes yes
#PubkeyAuthentication yes 
#AuthorizedKeysFile      .ssh/authorized_keys

to

Code:

 
StrictModes no 
PubkeyAuthentication yes 
AuthorizedKeysFile      .ssh/authorized_keys

(e)reboot iPhone


Here is the project folder to test your SDK headers installation in iPhone.

I have successfully compiled a modified SDK sample app (modified to non-Interface Builder verison) UICatalog

(i) copy it (using wget) and unzip it in iPhone

Code:

wget http://www.iphone.org.hk/attach/39773-UICatalog.zip  
unzip 39773-UICatalog.zip

(ii) then run

Code:

cd UICatalog 
make install

to build and install the SDK project in iPhone

After SpringBoard restart, test the UICatalog app in iPhone.

I gotta say, you're a great man. Thank you very much yet again.

I managed to get the SDK on the phone to use the gcc compiler. One thing to note was that stdint.h was missing. Just took the one from the toolchain port found in cydia.

Thanks, this has been a lot of help.
