Hi, I tried to build an recent linux 2.6.33-rc something in an unstable Debian chroot. I had the following issues (plus workarounds / fixes) - please don't hesitate to ask me if you have further questions. error: arch/mips/cavium-octeon/built-in.o: In function `prom_init': (.init.text+0x974): undefined reference to `early_serial_setup' arch/mips/cavium-octeon/built-in.o: In function `prom_init': (.init.text+0x974): relocation truncated to fit: R_MIPS_26 against `early_serial_setup' arch/mips/cavium-octeon/built-in.o: In function `flash_init': fix: enabled configuration for serial console support error: flash_setup.c:(.init.text+0x12dc): undefined reference to `simple_map_init' flash_setup.c:(.init.text+0x12dc): relocation truncated to fit: R_MIPS_26 against `simple_map_init' flash_setup.c:(.init.text+0x12ec): undefined reference to `do_map_probe' flash_setup.c:(.init.text+0x12ec): relocation truncated to fit: R_MIPS_26 against `do_map_probe' flash_setup.c:(.init.text+0x1314): undefined reference to `parse_mtd_partitions' flash_setup.c:(.init.text+0x1314): relocation truncated to fit: R_MIPS_26 against `parse_mtd_partitions' flash_setup.c:(.init.text+0x1330): undefined reference to `add_mtd_partitions' flash_setup.c:(.init.text+0x1330): relocation truncated to fit: R_MIPS_26 against `add_mtd_partitions' flash_setup.c:(.init.text+0x1340): undefined reference to `add_mtd_device' flash_setup.c:(.init.text+0x1340): relocation truncated to fit: R_MIPS_26 against `add_mtd_device' fix: set drivers/mtd to y (instead of m) error: arch/mips/cavium-octeon/built-in.o: In function `sched_clock': (.text.sched_clock+0x24): undefined reference to `__lshrti3' arch/mips/cavium-octeon/built-in.o: In function `sched_clock': (.text.sched_clock+0x24): relocation truncated to fit: R_MIPS_26 against `__lshrti3' workaround: in arch/mips/cavium-octeon/csrc-octeon.c #if (__GNUC__ < 4) || ((__GNUC__ == 4) && (__GNUC_MINOR__ <= 3)) replaced by something that always uses "the ugly way" ERROR: "i8253_lock" [drivers/input/misc/pcspkr.ko] undefined! fix: disable pc speaker support Cheers, Andi
