And before anyone tells me to go ask at the TT-Forums, read this thread on them. It explains why I'm asking here.

That aside. Those who've read that thread know what I'm going to ask, for those who don't want to, here's the problem.
No one can figure out how to cross-compile Win32 builds of OpenTTD on linux anymore. There's a wiki page on the OpenTTD wiki, which is outdated, and I personally have had no success with.

So I'm hoping someone can help me/us/the OpenTTD community out with this, and explain how exactly to achieve it.
And if no one minds, I (or you can yourself, of course) will add the information to their wiki page for their easy referance.

(Note - I found a set of mingw packages in my Ubuntu repository that seem to be useful for making Win32 builds - but I haven't figured out how they work yet.)

Thanks in any case.

Why do it ?

Versions are available for the most OS's :

http://www.openttd.org/en/download-stable

And where to get the source code ?

Sigh...
The source code is available at the same page you linked to, which I already know about. If I could use that for what I want to do, I would.

The reason I would want to is because there are those who want to produce patched Win32 builds, or builds of the custom branches such as the Cargo Distribution branch, but don't have a Windows PC to do it on.
Patches work on source code. Not on already compiled binaries.

You can also check out the source code by grabbing your terminal, installing svn and then running:
svn co svn://svn.openttd.org/trunk

I do know how to compile on both Windows and Linux. The problem remains that I cannot compile for Windows on Linux.
I wouldn't be asking if just downloading the Windows binaries was enough.

Alright, I'm going to bump this a bit, because I'm still looking for some instructions that work.

Yes, I'm still working with the source code, so I can provide patched versions of OpenTTD, for other OS.
The two target OS are of course Windows, and Mac.

Windows, I've found all kinds of ideas for this or that option, none of which have provided and executable Windows binary.
Mac I'll freely admit I haven't gone looking for yet, because firstly, I'd like to know what I'd need, in order to provide a Mac build as it is, let alone actually compile one on Linux.
