using Orbix 3.3 and Orbix 6.3 C++ libraries in the same applicationon Linux.

Hi All,
Im pretty new to Corba and Orbix. And i have at hand an application
which was using Orbix 3.0.1. I have kind of migrated it to Orbix 3.3.
The issue is that it has a dependency on another 3rd party software
which uses orbix 6.3. I was able to link fine, first linking the 3.3
ones with the application code and then the 6.3 libraries at the end
to the linker. I have the binary, but i get several kind of errors
when i try to bind/connect to another orbix 3.3 server. Sometimes it
connects tooo.
================================================== =========
Here the _bind gives an exception, and in the exception handling
code, free signals.

Sometimes it gives a segmentation fault here.. not sure whey it does
so..If you notice the destructor of Object is referring to some 6.3
orbix header file. Is there a way i can get away with this..

Firstly, am i doing the right thing using 6.3 and 3.3 libraries in the
same app? Is there a way to tell the GNU linker to keep the references
separate. Please help me out.

I'm very surprised you managed to link two different CORBA products
into a single executable (Orbix 3 and Orbix 6 are different products
rather than different versions of the same product). Now that you have
somehow managed to link them into a single application, you are
probably going to run into problem after problem. I recommend that
you give up on this approach. It would be better for you to migrate
your
Orbix 3.3 application to Orbix 6.3.

Thanks for your inputs Ciaran. I shall do that.
