Summary: Add TaskContext factory for corba transport.
Product: Toolchain
Version: 2.5.0

OS/Version: All

Severity: enhancement
Priority: P3
Component: RTT

When we use the corba transport for, eg, the gui part, we only need few methods
:

#include <rtt/transports/corba/TaskContextProxy.hpp>
...
RTT::corba::TaskContextProxy::InitOrb(argc, argv);
...
RTT::corba::TaskContextProxy::Create(m_root_proxy_name);
...
RTT::corba::TaskContextProxy::DestroyOrb();
...

The problem is that we need to link the app with omniorb because of static
instances hidden behind rtt/transports/corba/TaskContextProxy.hpp
(omniORB4/finalCleanup.hpp for instance).

This is due to recent changes in gcc. See :
https://fedoraproject.org/wiki/Features/ChangeInImplicitDSOLinking
https://fedoraproject.org/wiki/UnderstandingDSOLinkChange

I would like to be independent of the corba implementation and only link to
rtt-corba lib.

The http://www.orocos.org/forum/orocos/orocos-users/error-compiling thread on
the user ml, is similar to my problem, but my ${OROCOS-RTT_CORBA_LIBRARIES}
doesn't contain omniorb lib (which is normal imho).

I would like to submit you a patch that adds a "factory" (a bit confusing with
the design pattern...), and that encapsulate the TaskContextProxy...
