I am hitting compilation errors with the latest v3.2.4. I got through the

Now I have the errors:

function ‘void Opal::Account::on_edit_form_submitted(bool, Ekiga::Form&)’:

../../../../lib/engine/components/opal/opal-account.cpp:438: error:
exception handling disabled, use -fexceptions to enable
make[6]: *** [opal-account.lo] Error 1

I compiled the ptlib and opal libraries OK.  As I recall, -fno-exceptions
is used for opal.  Is there now a conflict?  How do I make a change
without editing every Makefile?

My goal is to get a working ekiga version on SuSE 11.1 (with KDE 3.5), on
a 64-bit machine.  It has been total frustration.  Version 3.0.1 that
comes with the system does not transmit sound either direction.  I found
and installed rpms for ekiga v3.2.4, and relevant libraries, from the SuSE
build service.  Execution immediately gave a segmentation fault.

It seems that your gcc is configured to not accept exceptions in C++
code. That is pretty weird. Check your default gcc configuration.
No, this is a gcc 4.4 problem, for sure.

There are about ten files which use exceptions, I think they have the same
problem (grep 'catch *(' softs/ekiga/ekiga-svn/ -r).

No, it's not that simple. The gcc man page says that, if the exceptions option is not specified, then GCC will normally enable it for g++ and disable it for gcc. However, -fno-exceptions gets specified by the configuration files (including the ptlib.pc file) for the compilations (including g++) of ptlib-2.6.2, opal-3.6.2, and ekiga-3.2.4. The compilation failure in ekiga is with g++, but it has explicitly been told 'no-exceptions'. The opal routine it was trying to use was also made with 'no-exceptions'.

It looks like gcc4.4 is doing what it is told to do.

Sorry, it was I meant: it is a g++-4.4 specificity (not problem).
