jQuery - New Wave Javascript

What you need to build your own jQuery

In order to build jQuery, you need to have GNU make 3.8 or later, Node.js 0.2 or later, and git 1.7 or later. (Earlier versions might work OK, but are not tested.)

Windows users have two options:

1. Install msysgit (Full installer for official Git), GNU make for Windows, and a binary version of Node.js. Make sure all three packages are installed to the same location (by default, this is C:\Program Files\Git).
2. Install Cygwin (make sure you install the git, make, and which packages), then either follow the Node.js build instructions or install the binary version of Node.js.

Mac OS users should install Xcode (comes on your Mac OS install DVD, or downloadable from Apple's Xcode site) and http://mxcl.github.com/homebrew/. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js.

Linux/BSD users should use their appropriate package managers to install make, git, and node, or build from source if you swing that way. Easy-peasy.

How to build your own jQuery

First, clone a copy of the main jQuery git repo by running git clone git://github.com/jquery/jquery.git.

Then, to get a complete, minified, jslinted version of jQuery, simply cd to the jquery directory and type make. If you don't have Node installed and/or want to make a basic, uncompressed, unlinted version of jQuery, use make jquery instead of make.

The built version of jQuery will be put in the dist/ subdirectory.

To remove all built files, run make clean.

Building to a different directory

If you want to build jQuery to a directory that is different from the default location, you can specify the PREFIX directory: make PREFIX=/home/jquery/test/ [command]

With this example, the output files would end up in /home/jquery/test/dist/.

Troubleshooting

Sometimes, the various git repositories get into an inconsistent state where builds don't complete properly (usually this results in the jquery.js or jquery.min.js being 0 bytes). If this happens, run make clean, then run make again.
