[asterisk-ss7] Error starting asterisk with libss7 support

[Andreas Kaufmann]

Hi,

when I start asterisk with libss7 support I get the following error message:

 > asterisk -c
...
[ Booting...

Because the chan_zap.c line 8122 is in a HAVE_SS7 block, I hope this is 
the right forum.

Any ideas what this errors mean?

Thanks,
Andreas
