Re: [Freeswitch-dev] FreeSWITCH mod_osp: undefined symbol OSPPTransactionSetSrcNetworkId**

13 Aug 2010

      Hi Patrick,

I have several questions,
1. Is /usr/lib64 included in the default link search path?
2. Did it report any warning or error message when you compiled mod_osp 
module?
3. Do you install several OSP Toolkit versions?
4. Is there any other libosptk.a under the link search path?
5. How did you build/install OSP Toolkit?

BTW, OSP Toolkit only provides static library. So from the nm output, it 
seems that OSP Toolkit was not linked into mod_osp.so.

Thanks,

Di-Shi Sun.

Dear Mr. Sun,
According to mod_osp.c in the FreeSWITCH sources you are the developer of 
this module. There is a problem with an undefined symbol in mod_osp with 
FreeSWITCH git from 8/10:
Platform:   CentOS 5.5 x86_64 (updated)
FreeSWITCH: git-07b8176 2010-08-10 18-51-06 -0400
OSPToolkit: 3.6.1
After installing OSPToolkit I enabled mod_osp and built and installed
FreeSWITCH. When I issue "load mod_osp" I see this error:
2010-08-11 21:00:29.284157 [CRIT] switch_loadable_module.c:926 Error
Loading module /opt/freeswitch/mod/mod_osp.so
**/opt/freeswitch/mod/mod_osp.so: undefined symbol:
OSPPTransactionSetSrcNetworkId**
I'm out of my league here but I tried to get as much info as possible.
/usr/lib64/osp/libosptk.a has the following symbols:
$ nm /usr/lib64/libosptk.a
[snip]
osptransapi.o:
00000000000006ed T OSPPTransactionSetSrcNetworkId
[snip]
Checking mod_osp I see the following:
$ nm /opt/freeswitch/mod/mod_osp.so

According to the nm manpage, the "U" means "undefined" so mod_osp does
not seem to pick up libosptk.a (during linking?).
Would you perhaps have any suggestions how I can fix this error?
Please let me know if you need more information.
Many thanks in advance!
Kind regards,
