I'm not sure if this topic would go here naturally, I put it here though 'cause this is the HLL section...

But say I wanted to write an OS using the booting code in FASM, and used C for everything else. I've looked at other sites (i.e. - http://www.osdever.net/) and most of the things there use what's called a linker script.

This may sound like a stupid question, but what is a linker script exactly and how does it work, and more importantly how can I create my own for GNU ld to work with GCC and FASM?

Thanks a bunch!

A linker script tells the linker how to combine the objects and what headers to write. ld is somewhat complex as it encompasses just about every operating system and output type out there.

Here's an online manual. You have some reading to do...
