You did make menuconfig ARCH=um and saved? Then possibly (due to a Kconfig bug) you _aren't_ building with default options. It probably took /boot/config-2.6.13.1 as default config, which is obviously wrong for UML. Is this the case for you?
Remove your .config, and do: $ make defconfig ARCH=um to get a sane one. Then you can change the configuration at your will. > I have been trying to build linux kernel 2.6.13.1 as UML but I am > getting these errors continusously. The -bs patches have a fix for this. However, I advise you to disable CONFIG_HIGHMEM, which beyond producing this errors can make UML slower when used. Instead, to use big amounts of memory, simply disable TT mode and run UML in SKAS0/SKAS3 mode. SKAS0 mode runs on normal hosts, and is a lot faster than TT mode. > <snippet> > > LD .tmp_vmlinux1 > arch/um/sys-i386/built-in.o(*ABS*+0x23e9ef7d): In function `__crc_kunmap': > module.c: multiple definition of `__crc_kunmap' > arch/um/sys-i386/built-in.o(*ABS*+0x5bf7768f): In function > `__crc_kmap_atomic': module.c: multiple definition of `__crc_kmap_atomic' > arch/um/sys-i386/built-in.o(*ABS*+0xd2c4a312): In function > `__crc_kmap_atomic_to_page': > module.c: multiple definition of `__crc_kmap_atomic_to_page' > arch/um/sys-i386/built-in.o(*ABS*+0x259446e): In function `__crc_kmap': > module.c: multiple definition of `__crc_kmap' > collect2: ld returned 1 exit status > KSYM .tmp_kallsyms1.S > nm: '.tmp_vmlinux1': No such file > No valid symbol. > make: *** [.tmp_kallsyms1.S] Error 1 > r -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
