In the previous post I've explained how to compile IceCat with native support for the language of your choice. Now, I'll explain how to create a xpi language extension to install in IceCat.
Note that the extension gets the name firefox-3.0.1-g1.locale.langpack (for the European Portuguese, the name is firefox-3.0.1-g1.pt-PT.langpack.xpi). I don't know if this is due to the language files, a makefile or something else.
To create a xpi extension, just follow all the steps preceding the compilation of IceCat, like described in the previous post. Then, compile IceCat without the locale flag (just sudo ./configure; sudo make), go to browser/locales inside IceCat's source and execute this command (replacing pt-PT with your locale):
- sudo make langpack-pt-PT
