1 Open H.323 Channel Driver for Asterisk
5 First public release on November 10th, 2002
8 Developed using: RedHat 7.2/7.3/8.0
13 Dependancies: openssl-0.9.6b
18 We have implemented this driver using Asterisk's RTP stack insted of trying
19 to implement a pseudo sound card driver.
21 NOTICE: Whatever you do, DO NOT USE distrubution specific installs
22 of Open H.323 and PWLib. In fact you should check to make sure
23 your distro didn't install them for you without your knowledge.
24 Check everything out of CVS. If you dont know how to deal with cvs, learn.
25 Also, if you are not using the listed versions of Open H.323 or PWlib
26 you are on your own, sorry. Older versions will NOT work, but newer
27 versions ~should~ work.
30 Most common compile error:
32 If you receive anything that says 'undefined symbol' you are experiencing
33 typical version skew. For example:
35 libh323_linux_x86_r.so.1: undefined symbol: GetNumberValueAt__C14PAbstractArrayi
37 You need to search and destroy every version of libh323 and libpt then
38 completely recompile everything
40 Example commands to make sure everything gets cleaned and then
41 rebult in proper order:
47 cd asterisk/channels/h323
50 (Note: Open H.323 or PWLib never get a 'make install')
53 Most common run-time error:
55 libpt_linux_x86_r.so.1: cannot open shared object file: No such
58 You have not set the LD_LIBRARY_PATH environment variable.
60 Example environment for sh/bash:
64 OPENH323DIR=$HOME/openh323
66 LD_LIBRARY_PATH=$PWLIBDIR/lib:$OPENH323DIR/lib
67 export LD_LIBRARY_PATH
69 We recomend puting the above directives into your /etc/profile so
70 you do not have to remember to export those values every time you
74 If you still have trouble please contact 'JerJer' in #Asterisk on
75 irc.freenode.net or send and email to jj@indie.org
77 If you happen to be lucky enough to segfault this code please run a
78 backtrace and send me the gory details. Segmentation faults are not
83 # /usr/sbin/asterisk -vvvgc
86 Segmentation Fault (core dumped)
91 # gdb /usr/sbin/asterisk core.1976
95 Send whatever shows up right after the 'bt'
98 Also, a full debug screen output is almost needed. Make sure you are
99 in the full console mode (-c) and turn on 'h.323 debug'. A nice way
100 to capture everything is to use the utility called 'script' (man script)
