NEED HELP WITH LINKER!! :D

[anti149]

Hay so I found a problem that is preventing me to compile my kernel :O the boot-loader and main.c compile fine (I am using header files in my C main), BUT when I try to link them to make kernel.bin it messes up here is my linker file(just using the one from Bran's kernel tutorial):

OUTPUT_FORMAT("binary")
ENTRY(start)
phys = 0x00100000;
SECTIONS
{
.text phys : AT(phys) {
code = .;
*(.text)
*(.rodata)
. = ALIGN(4096);
}
.data : AT(phys + (data - code))
{
data = .;
*(.data)
. = ALIGN(4096);
}
.bss : AT(phys + (bss - code))
{
bss = .;
*(.bss)
. = ALIGN(4096);
}
end = .;
}

and here is how I'm compiling the linker in batch file: ld -T link.ld -o kernel.bin start.o main.o

what am I doing wrong should I use a make file instead??

thanx for help!

Forum rules, read them.

1. How does it mess up? Does the linker error, does it end up with an invalid binary?

Sry here is the error it displays in my batch file when it reaches the linker part: main.o:main.c:(.text+0xe): undefined reference to 'printf'
but my header file and library have the function and it compiles fine in GCC just the linker has problems.

Do you have your own version of printf? You cannot use the C library's version of printf in your kernel. Any and all library functions that you call must be written and compiled in with the kernel.'

Edit: Oh, and your topic title? No. Don't do that. Make an intelligent title next time.

You're calling printf. You can't call a libc function that you haven't implemented yourself from your kernel.

I cant use C library? wow! (Me new to kernels in C used to ASM & C#) so I have to make my own cant use C library?

Okay, my turn: No. You cannot use the C library. Perhaps a little more research is in order before you write an OS in C?

OK do you have any suggestions or good tutorials to learn C kernel basics? (Preferably compatible with widows my Linux machine is down)

Again Forum Rules, read them
And, you see that link at the top of the page "The OSDev.org Wiki - Got a question? Search this first!"? Click on it.

Edit: (I seem to be a little snappy today, no idea why)

This was an obvious troll, but, continue.

Oh nvm I figured it out without using the C library making my own headers works fine hanks for your help though!
