1. Problem: Compiling kernel w/ gcc-elf
Hello guys,
Have anyone sucessfully compiled the kernel using gcc-elf? I could get
the object files without any problem. However, when ld tried to link up
the objects to build vmlinux, it failed. The errors are :
.........
arch/i386/mm/mm.o(.text+0x5ba): undefined reference to `pg0'
arch/i386/mm/mm.o(.text+0x604): undefined reference to `pg0'
kernel/kernel.o(.text+0x19e): undefined reference to `_current'
kernel/kernel.o(.text+0x1ab): undefined reference to `_last_task_used_math'
kernel/kernel.o(.data+0x39c): undefined reference to `sys_call_table'
kernel/kernel.o(.data+0x424): undefined reference to `floppy_track_buffer'
kernel/kernel.o(.data+0x2aac): undefined reference to `swapper_pg_dir'
mm/mm.o(.text+0x7c): undefined reference to `swapper_pg_dir'
mm/mm.o(.text+0x2a0): undefined reference to `swapper_pg_dir'
mm/mm.o(.text+0x2c6): undefined reference to `swapper_pg_dir'
fs/fs.o(.text+0xdfd6): undefined reference to `sys_call_table'
fs/fs.o(.text+0xe956): undefined reference to `sys_call_table'
.........
I have gone thru the .s files produced and found that it was due to the
number of underscore generated by the assembler in front of .data and
.text symbols.
Does anyone have idea for this problem?
Best Regards.
