Hi All,

we want to use alsa library for arm platform. while configuration we specified option for shared library. but its alwaye creating static library after compilation. when we build the test application pcm_min.c we got the following error.

/usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0x194): In function `snd_pcm_ladspa_free_plugins': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:188: undefined reference to `dlclose' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0xd28): In function `snd_pcm_ladspa_connect_controls': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:515: undefined reference to `log' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0xd50):/home/susovan/alsa/lib/ alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:515: undefined reference to `log' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0xd74):/home/susovan/alsa/lib/ alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:536: undefined reference to `exp' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0xd9c):/home/susovan/alsa/lib/ alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:526: undefined reference to `sqrtf' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0xdac):/home/susovan/alsa/lib/ alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:536: undefined reference to `log' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0xdd4):/home/susovan/alsa/lib/ alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:536: undefined reference to `log' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0x1fac): In function `snd_pcm_ladspa_check_file': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:1087: undefined reference to `dlopen' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0x1fc0):/home/susovan/alsa/lib /alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:1089: undefined reference to `dlsym' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0x20b8):/home/susovan/alsa/lib /alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:1132: undefined reference to `dlclose' /usr/lib_alsa/libasound.a(pcm_ladspa.o)(.text+0x20e0):/home/susovan/alsa/lib /alsa-lib-1.0.14rc4/src/pcm/pcm_ladspa.c:1124: undefined reference to `dlclose' /usr/lib_alsa/libasound.a(dlmisc.o)(.text+0xc): In function `snd_dlopen': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/dlmisc.c:64: undefined reference to `dlopen' /usr/lib_alsa/libasound.a(dlmisc.o)(.text+0x24): In function `snd_dlclose': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/dlmisc.c:85: undefined reference to `dlclose' /usr/lib_alsa/libasound.a(dlmisc.o)(.text+0xa8): In function `snd_dlsym_verify': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/dlmisc.c:115: undefined reference to `dlsym' /usr/lib_alsa/libasound.a(dlmisc.o)(.text+0x144): In function `snd_dlsym': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/dlmisc.c:161: undefined reference to `dlsym' /usr/lib_alsa/libasound.a(pcm_meter.o)(.text+0x74c): In function `snd_pcm_meter_avail_update': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_meter.c:106: undefined reference to `pthread_mutex_trylock' /usr/lib_alsa/libasound.a(pcm_meter.o)(.text+0xa54): In function `snd_pcm_meter_hw_params': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_meter.c:470: undefined reference to `pthread_create' /usr/lib_alsa/libasound.a(pcm_meter.o)(.text+0xaec): In function `snd_pcm_meter_hw_free': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_meter.c:483: undefined reference to `pthread_join' /usr/lib_alsa/libasound.a(pcm_meter.o)(.text+0xf84): In function `snd_pcm_meter_add_scope_conf': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_meter.c:664: undefined reference to `dlsym' /usr/lib_alsa/libasound.a(pcm_route.o)(.text+0x12c8): In function `snd_pcm_route_convert1_many': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_route.c:453: undefined reference to `rint' /usr/lib_alsa/libasound.a(pcm_share.o)(.text+0x1dd0): In function `snd_pcm_share_close': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_share.c:1243: undefined reference to `pthread_join' /usr/lib_alsa/libasound.a(pcm_share.o)(.text+0x21b8): In function `snd_pcm_share_open': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_share.c:1474: undefined reference to `pthread_create' /usr/lib_alsa/libasound.a(pcm_softvol.o)(.text+0x18a4): In function `softvol_load_control': /home/susovan/alsa/lib/alsa-lib-1.0.14rc4/src/pcm/pcm_softvol.c:665: undefined reference to `pow'

we tried with the following releases- 1)alsa-lib-1.0.14 2) alsa-lib-1.0.14a 3)alsa-lib-1.0.14rc4 But when we tried to build alsa shared library for x68 platform we did not face this problem , but when we built the alsa static library for x86 and tried to compile the test application we face the above "undefine reference " error.

Can any one help me to understand and solve this problem?

Thank you
