|
| == Requirements ==
| | This article is obsolete and has been replaced by the [https://theos.dev/docs/installation-ios theos.dev website]. |
|
| |
|
| === Mandatory Requirements ===
| | If you need historical installation instructions, you can find the last version of this article [https://iphonedev.wiki/index.php?title=Theos/Setup/iOS&oldid=6049 here]. |
| | |
| * A jailbroken iOS device with Cydia (or another package manager) installed.
| |
| | |
| === Optional Requirements ===
| |
| | |
| * Knowledge on how to use a command line terminal.
| |
| * Objective C knowledge.
| |
| * OpenSSH installed on your device and a computer that you can SSH into your device with (using MobileTerminal gets tedious pretty quickly).
| |
| | |
| == Installing Theos and it's dependencies ==
| |
| | |
| # Add the following repositories to your Cydia sources.
| |
| #* http://coolstar.org/publicrepo
| |
| #* http://nix.howett.net/theos
| |
| # Install the following packages in Cydia:
| |
| #* <code>Perl</code>
| |
| #* <code>Theos</code>
| |
| #* <code>iOS Toolchain</code>
| |
| # Check that Theos is installed on your device by running: <pre>echo $THEOS</pre><br />The output should be: <code>/var/theos</code>
| |
| | |
| == Setting up the iOS SDK ==
| |
| | |
| Navigate to http://iphone.howett.net/sdks and check which iOS SDK you wish to download.
| |
| | |
| # Create a directory for the SDK to be placed in: <pre>mkdir -p $THEOS/sdks</pre>
| |
| # Download the SDK temporarily and extract to the SDK directory: <pre>curl -ksL "http://iphone.howett.net/sdks/dl/iPhoneOSX.Y.sdk.tbz2" | tar -xj -C $THEOS/sdks</pre><br>''X.Y being the version numbers of the SDK, as seen in http://iphone.howett.net/sdks.''
| |
| | |
| == Additional Step for 64 bit (ARM64) Devices ==
| |
| | |
| With the current version of Theos (0.9.639-1), building on ARM64 will throw an error. The following will solve this issue.
| |
| | |
| # Create symlinks to support ARM64: <pre>ln -s $THEOS/makefiles/platform/Darwin-arm.mk $THEOS/makefiles/platform/Darwin-arm64.mk ln -s $THEOS/makefiles/targets/Darwin-arm $THEOS/makefiles/targets/Darwin-arm64</pre>
| |
| | |
| == Additional Steps for Ease of Use ==
| |
| | |
| === Automatically exporting environmental variables ===
| |
| | |
| Although exporting $THEOS to /var/theos is not necessary on iOS, it is useful, and tedious to do every time a terminal is opened. To automatically do this, bash's login scripts can be utilized to export these variables. First, the default shell must be changed to bash:
| |
| | |
| # Open the file /etc/master.passwd in a text editor (ifile or vim) and find the lines starting with "mobile" and "root". Change the text at the end of these lines from <pre>/bin/sh</pre> to <pre>/bin/bash</pre>
| |
| # Create a file named .bash_pofile in /var/mobile and add the variables to the file you created. EX: <pre>export THEOS="/var/theos"</pre>
| |
| | |
| === Avoiding using the root user === | |
| | |
| Using the root user while in a theos project for 'make' commands can cause many issues very quickly.
| |
| | |
| As your the environment you set up above stands, root is still needed for 'make install'.
| |
| | |
| To avoid the root user completely, we can bypass this by using ssh keys and remote install.
| |
| | |
| # Follow the guide at http://www.linuxproblem.org/art_9.html to add your ssh keys to the root user for passwordless ss, substituting '[email protected]' for 'a@A' and '[email protected]' for 'b@B' | |
| # Open $THEOS/makefiles/Darwin-arm/iphone.mk and near the bottom of the file, find the line <pre>TARGET_INSTALL_REMOTE := $(_THEOS_FALSE)</pre> and change it to <pre>TARGET_INSTALL_REMOTE := $(_THEOS_TRUE)</pre>
| |
| # add this line to the end of ~/.bash_profile <pre>export THEOS_DEVICE_IP=127.0.0.1</pre>
| |
| | |
| Now 'make package install' may be utilized.
