Hi,

I download the head of uclinux-dist trunk. Choose target as BF548-EZKIT and default on everything else. Got the following build errors:

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c:37:19: error: dlfcn.h: No such file or directory

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c: In function 'try_open':

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c:82: error: 'RTLD_NOW' undeclared (first use in this function)

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c:82: error: (Each undeclared identifier is reported only once

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c:82: error: for each function it appears in.)

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c: In function 'try_open_full':

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c:129: error: 'RTLD_NOW' undeclared (first use in this function)

../../../alsa-lib-1.0.18/src/mixer/simple_abst.c:129: error: 'RTLD_GLOBAL' undeclared (first use in this function)

make[7]: *** [simple_abst.lo] Error 1

Some relevant information:

uclinux-dist revision: 7890

linux-kernel revision: 6180

$ grep CONFIG_BINFMT_ELF_FDPIC linux-2.6.x/.config

CONFIG_BINFMT_ELF_FDPIC=y

$ grep ALSA config/.config

CONFIG_LIB_ALSA_LIB=y

# ALSA lib requires FDPIC ELF

CONFIG_USER_ALSA_UTILS=y

Regards,

Dong

enabling FDPIC in the kernel doesnt matter.  you need to select it as the userspace binary format.

Please update your uClinux-dist/vendor/ to SVN trunk.
