I'm attempting to compile kernel 2.4.20 on a sun ultra 2 using gcc-3.0 (3.0.4) from debian gnu/linux sparc woody 3.0r0.
The linux kernel faq (http://www.wsinf.edu.pl/doc/doc-linux-html/FAQ/Linux-FAQ-8.html) suggests that the linker is using a static libc for linking. The linker command below doesn't show that /usr/lib/libc.a is being linked in but perhaps it's implied (this doesn't quite make sense though, since kernels are usually 500k to 1 MB and libc.a is a little over 2MB on both i386 and sparc) ? In any case, is there any special magic I need to do to compile this ? I used 3.0.4 because 2.9.5 didn't seem to have a compiler for sparc64. Lots of thanks in advance. link error: ld -m elf64_sparc -T arch/sparc64/vmlinux.lds arch/sparc64/kernel/head.o arch/sparc64/kernel/init_task.o init/main.o init/version.o init/do_mounts.o \ --start-group \ arch/sparc64/kernel/kernel.o arch/sparc64/mm/mm.o kernel/kernel.o mm/mm.o fs/fs.o ipc/ipc.o arch/sparc64/math-emu/math-emu.o \ drivers/char/char.o drivers/block/block.o drivers/misc/misc.o drivers/net/net.o drivers/media/media.o drivers/scsi/scsidrv.o drivers/cdrom/driver.o drivers/pci/driver.o drivers/sbus/sbus_all.o drivers/video/video.o drivers/md/mddev.o \ net/network.o \ /usr/src/linux-2.4.20/lib/lib.a /usr/src/linux-2.4.20/lib/lib.a /usr/src/linux-2.4.20/arch/sparc64/prom/promlib.a /usr/src/linux-2.4.20/arch/sparc64/lib/lib.a \ --end-group \ -o vmlinux init/main.o: In function `check_bugs': init/main.o(.text+0x8): undefined reference to `_mcount' init/main.o: In function `rest_init': init/main.o(.text+0x28): undefined reference to `_mcount' init/main.o: In function `init': init/main.o(.text+0x88): undefined reference to `_mcount' init/main.o: In function `profile_setup': init/main.o(.text.init+0x8): undefined reference to `_mcount' init/main.o: In function `checksetup': init/main.o(.text.init+0x48): undefined reference to `_mcount' init/main.o(.text.init+0xe8): more undefined references to `_mcount' follow make: *** [vmlinux] Error 1
