According to the Derelict page, there already are unofficial bindings.
But I guess they wouldn't work with Derelict2 anyway.

You should declare the function pointer without the extern(C).
Example:
alias int function(void* test) FTInitFunc;
extern(C) int foo(void* test){ }
FTInitFunc foo_ptr = foo;
This worked for me.
That's a bug.

This will write the address of foo. Often when you link with C code

The problem you are experiencing comes from no dmd.conf being included

Yes, I was a bit confused by the syntax, but I found that type of
