Re: [GnomeMeeting-list] Problem :: Gnome Libraries + GM1.2.1

[Ashutosh Sharma <asharma samyak com>]

Hi,
    Sorry, but this thing has taken hell out of me... Everytime strange
things are happening...I did that thing atleast 10-20 times with the
same changes....
But that unexpected Async reply is coming at irregular attempts.
Sometimes it is working fine...
Anyway 1 gdb trace in which I got that prob is as follows:-

 And here I get the crash dialog box.

Also the thing that you pointed out regarding the compilation of the
full source of gnomemeeting and openh323, sorry but I am bothered about
one point:-

I am not changing anything in GM, but only in the OpenH323 then would I
need to recompile the GM also. I suppose no, because I am compiling the
OpenH323. And as suppose I only change the files like jitter.cxx and
rtp.cxx then I need to do only make && make install and that would
compile the changed files only. I don't think that I need to clean the
compilation and then recompile each and every file.

Please correct me if I am wrong in the following context as suppose I
change jitter.h then I need to recompile only jitter.cxx or all those
files that use jitter.h. I think make file takes care of this.

Sorry for such problems, but I am not getting anything in my hand
because of such problems.

Thanks and regards,
Ashutosh
