For me, opal compilation error:

/home/dedu/softs/ekiga/opal/include/asn/t38.h:169: undefined reference 
to `vtable for T38_UDPTLPacket_error_recovery'
/home/dedu/softs/ekiga/opal/lib/notrace/libopal_s.a(t38proto.o): In 
function `~T38_UDPTLPacket':
/home/dedu/softs/ekiga/opal/include/asn/t38.h:482: undefined reference 
to `vtable for T38_UDPTLPacket'
collect2: ld returned 1 exit status
make[2]: *** [obj_linux_x86_64_n/simpleopal] Error 1
make[2]: Leaving directory `/home/dedu/softs/ekiga/opal/samples/simple'

HTH too :o)
