How to distribute XPCOM component via XPI for FireFox 3?

I wrote an XPCOM component and an extension that uses it. XPCOM loads arbitrary DLL for its purposes.

How can I include XPCOM and DLL into XPI package?

From stackoverflow

• XPI is basically a zip file, which includes the DLL, among other things See https://developer.mozilla.org/En/Creating_XPI_Installer_Modules

  mojo : yes, but i can't find the way to load DLL from XPCOM. now i am struggling to get a path to extension directory to use in LoadLibrary call.

  Yarik : What is your environment? Win/UNix/Mac, Firefox/Thunderbird? THe paths to extension directories depend on that.

  mojo : I figure with IExtensionManager and IInstallLocation, you can neglect environment differences.

• I was able to find absolute path to my DLL via IExtensionManager and IInstallLocation, then load it via LoadLibrary().

  1. put DLL near XPCOM in my.xpi/components/
  2. figure out the path to extension via IExtensionManager and IInstallLocation
  3. LoadLibrary()
  4. profit
