I am trying to compile pwlib, openh323, and openmcu on a
linux (fedore core 2) server for use as a multipoint
reflector for my
family to use for videoconferencing. I have downloaded
current src of each from sourceforge, and am following the
directions on
this page - http://www.openh323.org/pipermail/ope
nh323/Week-of-Mon-20060724/077596.html to compile.
Here's the versions I'm working with.
pwlib_v1_11_1
openh323_v1_19_0_1
openmcu_v2_2_0
First, pwlib compiles correctly. When I try to compile
openh323, I get the following error (see ERROR #1 below)
If I go back into $HOME/pwlib/include, edit ptlib.h, I can
uncomment line 302 (#include <ptlib/sound.h>) and try
to recompile
pwlib, I get ERROR #2, and pwlib fails to compile.
Next, I tried compiling pwlib normally (which works) and
then uncommenting that line 302 (#include
<ptlib/sound.h>) in ptlib.h, then
compiling openh323 again. This works until I hit the
following error (similar problem but line 308, #include
<ptlib/video.h>) ERROR
#3
Finally, with both lines 302 and 308 uncommented, openh323
compiles. I then compiled openmcu per the instructions,
with no errors.
I am running openmcu as root, with -x -c as the options. It
seems to start up just fine, and it's running since I can
connect to it
with NetMeeting from a windows box, but I just see the
"Open MCU" graphic as the video.
Can anyone point me in the right direction to figure out why
my video isn't working? Also, if anyone has a good
suggestion as to an
alternate WinXP H.323 client I'd appreciate it.
Thanks,
Brian
