Building the FireBreath Plugin

Get the source

First thing is first; get the source code.

To get a copy of the source, see the download page.

Generate the example project files

To generate the project files execute:

The project build files will all be generated into the buildex/ directory under the project root.

If an error is indicated or if cmake crashes, this may be due to CMake Bug 13463.  If the bug has not been fixed yet, use the workaround is given in Step 5 of that bug's Steps to Reproduce which is better explained in this post.

Generate your own project files

If you have created your own project in the projects/ directory, you can build it by running the same command as for example projects, but without "examples".

To generate the project build files:

The project build files will all be generated into the build/ directory under the project root - this only has to be done after either adding or generating another FireBreath project.

Don't forget to check the Prep Scripts page if you want to build for specific CPU architectures or against different SDKs.

Build the Plugin

The Xcode Projects

As alluded to in the general overview, if you have N plug-in projects in your projects/ directory, running will create N+1 Xcode projects.  That is, for each of your plugin projects, you'll get a single-plugin Xcode project, and you'll also get a combined Xcode project, in which each plugin project is a Bundle Target.  The single-plugin projects are nicer to look at in the IDE, but they have only one real Target (the plugin bundle) and do not make a reference to nor have a dependency set upon the half-dozen FireBreath and Boost libraries, even though in fact they do depend on them.  The Firebreath and Boost libraries are only built by the combined Xcode project, which has proper dependencies set within it.  Therefore, you must build the combined project first, in all desired configurations, before building any of the single-plugin projects.  And unless you're one of those people who can track project dependencies in their head for months and years, it's probably safer to use the combined project for all purposes.

Using xcodemake

The example plugin can be built by changing to the directory buildex/ and executing:


To build your own plugin project (using the combined Xcode project), change to the directory build/ and execute:


Using Xcode IDE

Open the combined project with Xcode:

From there you can either build all projects (ALL_BUILD) or specific plugin targets.

Make the plugin accessible to browsers

You have the option making the plugin available to all users or to simply install it for the local user only. Unless there is a good reason for it, install it for the current user only.

Installing a plugin for the current user

To install a plugin for only the currently logged in user, symlink the <Plugin Bundle> to ~/Library/Internet Plug-Ins

ln -s buildex/projects/FBTestPlugin/Debug/FBTestPlugin.plugin ~/Library/Internet Plug-Ins/

Installing a plugin for all users

To make a plugin globally available to all users, symlink the <Plugin Bundle> to /Library/Internet Plug-Ins

ln -s buildex/projects/FBTestPlugin/Debug/FBTestPlugin.plugin /Library/Internet Plug-Ins/

Open in your browser and play with it

Open the file buildex/projects/FBTestPlugin/gen/FBControl.htm in your preferred browser

Use Jash or firebug (or whatever) to make calls on the plugin. For supported calls, check out projects/TemplatePlugin/MathAPI.cpp.

A few JS commands to try:

plugin().echo("echo this string!")
"Echoing: echo this string!"
