[omniORB] EXT : Trying 4.1.7 on Visual Studio 12

[James Kulp]

This problem did in fact relate to 64 bit vs 32 bit.
On a 64 bit Windows 7 installation, Visual Studio 12.0 (2013), as a 
default, compiles code that will not link against the python 64 bit 
installation.  The error is based on symbols that have one less 
underscore in the 64 bit python dll import library (.lib).

I succeeded by using a 32 bit python installation on the 64 bit windows 
installation.  I did not yet try to make a completely 64 bit 
installation of WIndows 7 + python + omniorb.

The two other glitches I had to fix were:

1. The "user access controls" had to be disabled in the control panel 
(and a reboot of course).  Otherwise the gnuwin32-lite "install" program 
would not run.

2. The "clwrapper" code had to access the registry using 
HKEY_CURRENT_USER rather than HKEY_LOCAL_MACHINE for the "cygdrive 
prefix" entry.  The code should probably try both.

I also had to do "veryclean" since some dependency files (*.d) had 
incorrect dependencies (a cygdrive prefix issue).

I also note that "veryclean" does not clean/rebuild the windows wrapper 
tool executables.  The build process is not set up to rebuild these,
and that was required to make the registry key fix.

If I get around to the pure 64 bit setup, I'll report on that later.

Cheers,
Jim

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 haveto set up some specific environment variables to do this (PYTHONPATH, PYTHONHOME).
