Apologies for the many questions. Yes, I've tried google, couldn't seen to find what i'm looking for. I'm following JamesM's Tut. Using windows with Cyg. I Have boot.o and main.o, how do i link them, i have the link.ld linker script file, but i don't understand how to link them. I looked to ld --help, but couldnt figure out how to use link.ld to link the two into "kernel".
thanks

Have you tried something like this?
Code: Select all
ld -T link.ld -o kernel.prg main.o
where link.ld is your linker script, kernel.prg is the output file and the rest is a list of input files?
(By the way, unless you know what you're doing without it, you should build a cross compiler and linker, see the wiki for instructions.)

Well, in one example you typed "\Link.ld", and the other one you typed "/Limk.ld". I think you meant Link

I did infact mean Link, but in cygwin, my problem still stands

iirc, you need /cygdrive/c/link.ld if you reference windows drives

I'm no Windows guru, but the solution seems rather obvious... you accidentally named the file "Link.ld.txt" instead of "Link.ld".
Perhaps OSDev is a little bit out of your league...

no, its not saved as txt. its link.ld, cuz where it says "file type: .txt" i changed to *all files* so it has no set file type.

Nah, windows is just like that lol...
I don't know what to say... I have my linker script in my kernel's directory, no problem there. Just move the linker script to where the rest of your files are
