You can't use alt_main() _and_ the alt_irq_register() function. You've got to be using a program with main(). I know that you mentioned that you had troubles compiling code with main() in it, but you have to have it if you want to use the HAL functions. (like alt_irq_register())

By using alt_main() you're telling the tools that you don't want to use any of the HAL's functionality.

The count_binary() example shows you how to do this.
