[OTR-dev] OTR + Second Life Client

[chris-tuchs at hushmail.com]

Sorry for the spam, but I am reposting to the devs list since that 
seems to be a better place than the users list.

I am working on integrating OTR into the second life client to 
encrypt IMs between users.  Is there some stuff I can read about 
getting a windows program to happily talk with libotr?  In 
particular the client is compiled with a Microsoft Visual C++ 
compiler, and not Cygwin's mingw + GNU C/C++.  Is there sample code 
of a Microsoft windows program communicating with libotr that I can 
look at?  Alternatively, has someone ported libotr to compile with 
the MS compiler?  Thanks for your time.

To get really technical, I was able to use cygwin to naively do 
"./configure; make" but the result was a ".a" file which I don't 
think the microsoft compiler is going to be happy with.  When I 
compile the second life client using the microsoft compiler, these 
are the sorts of compile time errors I get when including proto.h 
(from the libotr src directory.)
