[omniORB] EXT : Trying 4.1.7 on Visual Studio 12

Sun Nov 3 16:52:23 GMT 2013

Thanks for feedback.
I installed the 2.7.5 MSI  for x86_64 from the python site.
My windows 7 system in 64 bit, confirmed in the control panel.
There doesn't appear to be any 64 bit specific configuration in omniorb.
Python headers look for #ifdef _WIN64, but I notice that the VS12 
compiler does not set this.
(but this probably does not relate to the problem at hand).
It looks like the compiled omniidl files are referencing dll symbols 
(__imp__).
Using dumpbin /all on python27.lib, it shows, e.g., a symbol:
__imp_PyType_IsSubType
(note single underscore after "imp")

Where as the undefined in the error message is:

idlpython.o : error LNK2019: unresolved external symbol __imp__PyType_IsSubtype referenced in function _IdlPyCompile

Which is double underscore after the "imp"??

There are both a 64-bit and 32-bit versions of Python, and you must download the correct version of python to support the build.  You can have both Python implementations coexist on the same machine, but you have to set up some specific environment variables to do this (PYTHONPATH, PYTHONHOME).
