alsalib symbol problem

[Florian Bomers <Florian.Bomers@sun.com>]

Hi,

my code lists all available cards/devices/subdevices. As a stand-alone program,
it works fine and it links dynamically to libasound.so . However, when I use the
same code in my library, I get the following at run time (the "Opening..." and
"ERROR..." lines are generated by my code):

Opening alsa device "hw:0"...
ALSA lib dlmisc.c:100:(snd_dlsym_verify) unable to verify version for symbol
snd_config_hook_load
ALSA lib conf.c:2655:(snd_config_hooks_call) symbol snd_config_hook_load is not
defined inside (null)
ALSA lib conf.c:3066:(snd_config_update_r) hooks failed, removing configuration
ERROR: snd_ctl_open, card=0: No such device or address
Opening alsa device "hw:1"...
ALSA lib dlmisc.c:100:(snd_dlsym_verify) unable to verify version for symbol
snd_config_hook_load
ALSA lib conf.c:2655:(snd_config_hooks_call) symbol snd_config_hook_load is not
defined inside (null)
ALSA lib conf.c:3066:(snd_config_update_r) hooks failed, removing configuration
ERROR: snd_ctl_open, card=1: No such device or address

Why does this happen ? I searched the mailing list archive and only found an
explanation that symbols don't match and I need to recompile the ALSA lib. In my
case it's a clean install of ALSA on a newly installed red hat system. There was
never any other version of ALSA. 

Thanks for any help,
Florian

Configuration:
 Pentium II
 Red Hat 7.3
 ALSA 0.9rc3 drivers and libs
 kernel 2.4.18-10 (updated sources and kernel from red hat's web site)

/proc/asound/cards:

                     Ensoniq AudioPCI ES1371 at 0x1440, irq 10
1 [ESS ISA        ]: ES1868 - ESS AudioDrive ES1868
                     ESS AudioDrive ES1868 at 0x220, irq 5, dma1 1, dma2 3

Compiled on Sep 16 2002 for kernel 2.4.18-10 with versioned symbols.
