[Qt-interest] Deploy Application on Windows

[Malyushytsky, Alex]

Tiago,

I am sorry sending e-mail to your box directly.
Here is forwarding to the mailing list:

>> Building both service pack levels would be extremely difficult.

I would not consider it too difficult. You don't even need extra computer for it, just use VM.

I would expect QT to be tested and build with all service packs.
But as for me it does not make a lot of difference.

Having a commercial license I always had to build QT on my computer (since QT3).

For some reason trolltech and currently nokia (at least up to QT version 4.4.3 ) believe that there is no 64 bit Windows system yet and does not provide 64 bit binaries for Windows (msvc compiler).

Even though I would not probably even buy these days a computer with 32 Windows (this means 3 Gb of memory for Windows XP maximum), there is still no 64 bit binaries to download.

So I think you can safely skip upgrading your compiler. I would say that this will effect less than half of your customers.

But a good alternative is to upgrade and add 64 bit binaries to download page :)

Regards,

Alex Malyushytsky

That's correct.

The VS2005 build is SP1.
The VS2008 build is not SP1.

Building both service pack levels would be extremely difficult. So we're
considering what to do now for VS2008. If we leave it as it is, people who
have upgraded like you will have problems. If we upgrade, then people who
haven't upgraded yet will have problems.

Ideally, we wouldn't upgrade the compiler in our package builder until
4.6, but it looks like something we'll have to do sooner than that.

In other words, blame Microsoft for breaking binary compatibility too
often.
