Cannot compile kernel in Bran's Kernel Development Tutorial

crasher · Post by **crasher** » Thu Jan 24, 2008 2:25 am

Has anyone tried the small kernel developed in Bran's Kernel Development Tutorial. I tried it in Cygwin,using the downloaded bran's kernel package.
When I used the build.bat inside this package, I got
"start.o file not recognized". I thought this was because
nasm file format flag is "-f aout", so I changed it to "-f elf".
This time I got "cannot perform PE operation on non-PE file format". Other file formats were tried out but failed.

Did anyone experience this issue?

Build a GCC_Cross_Compiler in Cygwin

Use MinGW, leave nasm's output format as elf, and change LD's output to pei-i386.
ex. in link.ld

Code: Select all

OUTPUT_FORMAT("pei-i386") <---
ENTRY(_Init_Start)
_Data_Physical_Addr_Load = 0x00100000;

It works for me.

On Vista it crashes ld.exe

If you're using windows xp I personally recommand DJGPP as your compiler, LD supports the "binary" output format , and I think elf-i386 too , but you really only need the flat binary format that GRUB can understand directly.

This is normal.
Hang in there

Stick with cygwin and the cross compiler then
