In case youare interested I can submit my MinGW development environment for LO --- the office
as stand-alone "beast" seems to work pretty well with some adjustments in the code (at
least as far I was able to test it...). Please contact me directly on my e-mail account, I think
there is too much code to be transferred via the list...

Difficulties arise as soon as the UNO-environment contacts the office and tries to get information
with regards to services and interfaces. To be very cautious: I have the feeling that the information
submitted by the office is correct, but somehow allocated memory in the UNO bridge seems to get
corrupted (under very special circumstances I was able to remote control the office to create a
new document...). Since the UNO-bridge is based on several threads my guess is that there is a
problem with thread-safe use of shared memory. Unfortunately, at the moment I am bound with a
money earning project, so my time for this issue is rather limited. However, I definitely will help in
any possible way to solve this problem.

Well, I use a 2 years old SDK (MinGW) which is able to connect to an off-the-shelf MS-LibreOffice.
Sure, there are some shortcomings (not all event listeners work properly), but for my application
it is sufficient.

SDK and Linux is a dream - it simply works.
SDK and Windows is not so easy (I have problems to compile the SDK stuff under MSVC - however
my MSVC knowledge is rather small; I definitely would prefer MinGW).
A (Mac-addicted) colleague told me that the SDK for MacOS available half a year ago only contained
code for 32-Bit Macs, which does not work with recent 64-Bit machines/os'es. I don't know the actual
situation with regards to that issue, but I would expect that using the correct wordlength the MacOS-SDK
should be comparable to the Linux version.

Best wishes,
Helmar
