implicit casting

[SphinCorp]

I am getting a casting error with:

page_directory[0] = page_table;

where

unsigned long *page_directory = (unsigned long *) 0x9C000;
unsigned long *page_table = (unsigned long *) 0x9D000;

Note that this is to initialize paging at kernel level, so stdlib.h is NOT an option, as malloc() -- a memory allocation function -- is to be part of the memory manager this calls. how would I explicitly type-cast that?

Well, what's the type of page_directory[0]? page_directory is a pointer to unsigned long, right? So after an offset and dereference you'd be looking at an unsigned long, thus:

page_directory[0] = (unsigned long)page_table;

That will make your error go away.
