Ive been playing around with grub and a small kernel using djgpp and its AT&T syntax style assembly language. gcc version is 2.953, ld version is 2.11.2. nasm -o start.o -f elf start.asm gcc -o kernel.o -c kernel.c gcc -Wall -o asm.o -c asm.S ld-elf -T kernel.ls asm.o start.o kernel.o -o kernel // <<< problem line the nasm file compiles and links and so does the C file. The asm.S file compiles but doesn't link it says it can't recognize the file. Do I need a different linker? Any ideas? Here is the linker script: /* kernel.ls */ physical_load_addr = 0x00101000; ENTRY (KernelEntry) SECTIONS { . = physical_load_addr; .text : { *(.text) *(.rodata) } .data ALIGN (0x1000) : { *(.data) } .bss : { _sbss = .; *(COMMON) *(.bss) _ebss = .; } } I can post more code and info if needed. Thanks for your help Dylan
