This page contains instructions for installing Theos and preparing a new project.
Definitions
$THEOS
is the directory where Theos is installed on your machine. It is platform dependent.
Requirements
- A modern operating system (Mac OS X, iOS [jailbroken], Windows [using Cygwin], and most variants of Linux should work) with the following set of utilities:
- curl
- git
- make
- openssh
- perl
- rsync
- python (if on Windows)
- Some form of a toolchain or official SDK
- Access to a terminal emulator and some knowledge of how to use it
- Objective-C knowledge
More detailed explanations of these requirements are given in the next section, and are dependent on the environment you use.
Setting Up Dependencies
For Mac OS X
Mac OS X comes with most of the necessary tools (subversion, curl, and perl) by default. You will still need compilation tools and the iOS SDK, and the easiest way to obtain both of these is by installing Xcode from the App Store. Consider installing Command Line tools for Xcode as well, as it contains numerous tools that complement Xcode.
For Linux
Like OS X, most distributions come pre-packaged with the aforementioned tools. On Debian-based distros, APT can be used to install the tools like so:
sudo apt-get install git perl curl
If your distro uses RPM, the process is very similar.
For iOS
Dependencies:
Theos as a package depends on bash, grep, dpkg, coreutils, ldid, rsync and make, so the utilities mentioned in the requirements are automatically installed.
Install a Toolchain:
See On-device toolchains for details.
Also for Linux and iOS (and other operating systems other than Mac OS X): Retrieving SDKs
If you aren't using OS X, you must download an iOS SDK. See Retrieving SDKs for details on this.
Take the SDK and put it in $THEOS/sdks
(if it does not exist, create it), with a folder name like iPhone7.0.sdk. As of version 0.9.523, Theos accepts multiple SDKs in that folder.
Each SDK folder should have these folders: Developer, System, usr; and these files: ResourceRules.plist, Entitlements.plist, SDKSettings.plist.
Note that if no SDKs are provided, the following error will be displayed:
".../theos/makefiles/targets/darwin-arm/iphone.mk:21: *** first argument to 'word' function must be greater than 0. stop."
Installing Theos
On Mac OS X or Linux
- Open a terminal window.
- Choose a location for Theos to be installed. If you are unsure, a good choice is /opt/theos.
export THEOS=/opt/theos
- If you chose a location outside of your user's home directory, you will probably need to run some or all of the following commands with root permissions.
- Download the latest version of Theos:
- Using git:
git clone git://github.com/DHowett/theos.git $THEOS
- Alternatively, you can use svn, if you prefer:
svn co http://svn.howett.net/svn/theos/trunk $THEOS
- Using git:
- Download ldid to $THEOS/bin:
git clone git://git.saurik.com/ldid.git cd ldid git submodule update --init ./make.sh cp -f ./ldid $THEOS/bin/ldid
- Add Theos environment variables to your
~/.bash_profile
(or the equivalent for your shell). Open~/.bash_profile
(create it if it does not exist) in your favorite editor and add this on the last line, replacing the device name with your own device's name (replacing spaces with dashes) or its IP address:export THEOS=/opt/theos export THEOS_DEVICE_IP=example.local THEOS_DEVICE_PORT=22
(To get your device's IP address, go to settings, Wi-Fi, then press the i on the network you are currently connected on, and then see where it says IP Address. This is what you type in, if you don't want to use a device name.)
Load this into the shell with. ~/.bash_profile
, or close the terminal window and launch a new one. - As the substrate library does not come installed on these platforms nor bundled with Theos, copy
/Library/Frameworks/CydiaSubstrate.framework/CydiaSubstrate
from the device to your local$THEOS/lib
folder and rename it tolibsubstrate.dylib
.
On iOS
(On your iOS device:)
- Create a file at /etc/apt/sources.list.d/coredev.nl.list containing the following line:
deb http://coredev.nl/cydia iphone main
- Create a file at /etc/apt/sources.list.d/howett.net.list containing the following line:
deb http://nix.howett.net/theos ./
- Make sure APT 0.6 Transitional Package is installed before doing this step. As root, issue these commands (using either SSH or MobileTerminal):
apt-get update
apt-get install perl net.howett.theos
Note: For armv7 devices, a library file is corrupted regarding Perl. If you receive 'Illegal Instruction: 4' when attempting to run the Theos NIC after installation, create this script to resolve the issue with these steps:
1. Use a text editor and create a file called "perlfix.sh" without the parentheses.
2. Copy and paste the following code into the file:
#!/bin/bash sed -i'' 's/\x00\x30\x93\xe4/\x00\x30\x93\xe5/g;s/\x00\x30\xd3\xe4/\x00\x30\xd3\xe5/g;' /usr/bin/perl ldid -s /usr/bin/perl sed -i'' 's/\x00\x30\x93\xe4/\x00\x30\x93\xe5/g;s/\x00\x30\xd3\xe4/\x00\x30\xd3\xe5/g;' /usr/bin/rsync ldid -s /usr/bin/rsync
3. Copy this file to your device via SSH or a method of your choice, the directory doesn't matter.
4. As root, execute the script by issuing the following command using SSH or MobileTerminal:
sh <pathtoscript>/perlfix.sh
Creating a Project
Theos lets you create new projects based on templates using the New Instance Creator (NIC). You do not need to be root to do this step, nor should you be. Start the NIC wizard using the following command:
$THEOS/bin/nic.pl
NIC will prompt you for all the necessary information before creating a project.
NIC Example
Here is an example of what you will see when using the NIC to create a project (with user input shown in bold):
$ $THEOS/bin/nic.pl NIC 1.0 - New Instance Creator ------------------------------ [1.] iphone/application [2.] iphone/library [3.] iphone/preference_bundle [4.] iphone/tool [5.] iphone/tweak Choose a Template (required): 1 Project Name (required): iPhoneDevWiki Package Name [com.yourcompany.iphonedevwiki]: net.howett.iphonedevwiki Authour/Maintainer Name [Dustin L. Howett]: Instantiating iphone/application in iphonedevwiki/... Done. $
The above will create a folder ./iphonedevwiki in the current working directory - make sure you have permissions to create a folder.
Making your Project
When you have finished developing your tweak/app, you may want to distribute it, either to your own device, or to an external source.
When you are making the project, type this in the terminal, in your project folder:
$ make package
This will generate a .deb file, which you can distribute to people or to repositories.
If you want to install the latest package, type:
$ make install
It will then ask for your root password and install the .deb onto your device. If you haven't changed your root password, the default password is alpine. Make sure you change your root password, which you can do with passwd (see "Root Password How-To" on the Cydia homepage for detailed instructions).
Further Reading
You can learn how to do Makefiles with theos on http://uv.howett.net/ipf.html. Start over there.
For general advice on beginning development for jailbroken iOS, see Getting Started.
Getting Help
If you need further assistance, or if you have other questions about Theos itself, feel free to connect to #theos on irc.saurik.com using your preferred IRC client. If you don't already have a preferred IRC client, you can learn more here: IRC.
Troubleshooting
To-do: add common errors people get when setting up or during build. One such error is missing the substrate library.
