Re: Video Conference - not Konference
by Henning on Thursday 17/Jul/2003, @06:02

I converted the SRPM and tried to compile videoconference under Debian unstable.
Then I installed libpt[-dev] and libh323[-dev] but it still fails to compile. I guess videoconference does not like my gcc 3.3.1 :-(

from videoconference_part.cpp:45:

> vcdevice.h:54: error: syntax error before `{' token

Your problem is the same as mine. In that line it's trying to inherit from class PVideoOutputDeviceRGB which doesn't exist in your headers (pwlib 1.4.x probably?) That's why you get the error.

If you install version 1.5 of pwlib it _should_ compile fine.
