Linking help

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.)

hmm. i try:

Code: Select all

 ld -T C:\Link.ld

and

Code: Select all

 ld -T C:/Limk.ld

and for both it says:

"cannot open linker script file - No such file or directoy

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

WTF. It still doesnt work. no such file or directory...grr...

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
