[omniORB] OmniORB wilth DLL

[Ulf Stoermer]

Hi,

your problem isn't specific to OmniORB and
is the same with any Windows DLL. By default
the Windows compiler doesn't export any symbols
from your library. Instead you have to tell explicitly
which symbols you want to have exported.
Have a look at the Microsoft online documentation:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/_core_export_from_a_dll
_using___declspec.28.dllexport.29.asp

Cheers

Ulf

Subject: [omniORB] OmniORB wilth DLL


Hi all,
I want to create DLL files with OmniORB.
I have a class
class __declspec(dllexport) Object
{
private:
 CORBA::ORB_var orb;
...
...
}

When I compile, there's warning:
warning C4251: 'orb' : class 'CORBA::ORB_var' needs to have dll-interface to be used by clients of
class 'Object'
        d:\programs\omniorb-4.0.4\include\omniorb4\corba_vartypes.h(191) : see declaration of
'ORB_var'

How can I solve this problem.
Thanks in advance for any help.
