Creatition Of Xpcom Components

I'm creating an XPCOM component using a tutorial as a reference. However, when I run the following command it completes successfully but doesn't produce any .h file: xpidl -m heade

Solution 1:

No, XPCOM is not outdated but this tutorial is. The documentation recommends using pyxpidl:

header.py -I [XUL_RUNNER SDK\IDL] -o myfile.h myfile.idl
