<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The problem was due to conflict of data
type definition for wchar between OmniORB and my sample projects. In my
samples, I’m using my own definition for wchar as a 16 bit entity using “Unsigned
Short”. But OmniORB uses its own CORBA::WChar data type. So wherever I’m
using the CORBA::WString methods, the linker reports that all of them are
unresolved symbols along with “Unsigned Short” as the parameters of
those method signatures.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Actually, we can override the CORBA::WChar
data type by our own data type in omniORB. It can be done through the manually
in “$...\include\omniORB4\local_config.h” file in omniORB source
distribution. After changing it, rebuilt the omniORB again. All the linking
issues have been resolved. It works fine.<o:p></o:p></span></font></p>
