What you need to have installed

This is what I recommend you have installed for developing.

Linux, I have Ubuntu 9.04
The Toolchain 2.0 with the latest headers, on Linux.
Saurik’s ldid (on Linux and on the iPhone, in case you have trouble with any of them).
sudo (you’ll need to install this on the iPhone, on linux it comes by default)*

Also, I use emacs to write my code, it has a very nice auto formatting for code, supports a lot of languages, and has a lot of shortcuts. You don’t need it at all, but I love it . The only thing is that it goes crazy when using .h files and setting @property’s, so for modifying I use nano.

*You’ll need to add mobile to the list of users who can use sudo. To do this, log in as super user, and then use the command visudo:

1
2
3

$ su
$ [your password]
$ visudo

Then scroll down to where it says

1	root ALL = (ALL) ALL

And, below, add the same line but with mobile instead of root:

1	mobile ALL = (ALL) ALL

Installing ldid

You’ll need ldid to sign your code, you can get it on the iPhone by doing:

$ sudo apt-get install ldid

Here’s how to get it on Linux/OX S:
First, download from saurik’s with this:

$ wget http://svn.telesphoreo.org/trunk/data/ldid/ldid-1.0.610.tgz

Now, Unzip it:

$ tar -zxf ldid-1.0.610.tgz

Move to the result folder:

$ cd ldid-1.0.610

Compile it:

$ g++ -I . -o util/ldid{,.cpp} -x c util/{lookup2,sha1}.c

And put it in the bin folder:

$ sudo cp -a util/ldid /usr/bin

Now, to sign a binary, just do:

$ ldid -S FILE
