Hi, I'm trying to build a u-boot image for our arm board with ubifs support. I have defined #define CONFIG_CMD_UBI #define CONFIG_CMD_UBIFS #define CONFIG_RBTREE #define CONFIG_LZO When building fs/ubifs/lpt.c, I encountered "undefined reference" errors. /home/r65388/uboot-v2009.08/uboot-imx/fs/ubifs/lpt.c:81: undefined reference to `fls' /home/r65388/uboot-v2009.08/uboot-imx/fs/ubifs/lpt.c:82: undefined reference to `fls' /home/r65388/uboot-v2009.08/uboot-imx/fs/ubifs/lpt.c:83: undefined reference to `fls' /home/r65388/uboot-v2009.08/uboot-imx/fs/ubifs/lpt.c:84: undefined reference to `fls' fs/ubifs/libubifs.a(lpt.o):/home/r65388/uboot-v2009.08/uboot-imx/fs/ubif s/lpt.c:87: more undefined references to `fls' follow The function fls is defined in include/asm-ppc and there's no such functions in include/asm-arm. Is ubifs a common code or specified for ppc? Thanks~~ Yours Terry General Business Information Freescale Internal Use Only Freescale Confidential Proprietary
