Hi Everyone,

Will win64 native build exist on 3.5.0 or at least 3.5.x releases?

Are we using the Microsoft Free Developer Tools like Visual Studio 2010

for Windows builds (win32 and win64 ones)?

No. You can't use the Free Developer Tools if you want to compile
everything, as some components require ATL, for example, which is not
supported in the Free Compilers. There are a few workarounds to this
and you can make it work, but the safest way is to compile LibO with
the Visual Studio Professional version if you want to distribute the
version. If you are just experimenting, it doesn't matter.

We could think about it (win64 native build) like a GSoC project? Or like a
project to be financed by a local Community?

What's the real cause not to reach this waste Windows platform (win64)? We
could imagine a big data processing / simulation / ..., but also a more
efficient platform usage than WoW64...

The real causes is that is complicated and nobody is working on it, we
added compiler support (the shell extensions are using it), etc. but
some serious work has to be done in the  C++/UNO bridges and other
bits. None of them are trivial.

If your client is interested in this, he might consider funding the Win64 port.
