Re: 0.83.dev.20100507 and Visual Studio 2010

Harry:

Let's see if we can just focus on the test app for the moment.
I believe that Qt does have the ability to link to legacy windows Dlls, but we'll focus on the test app for now.

Please send the code for the test app. Were you able to make the changes to the included headers?

Paul

Thanks for that.

This version "breaks" my Visual Studio test app (it crashes upon calling dbopen).

I think it's exactly the same behaviour I was getting...



I'm afraid it also doesn't work at all from Qt.

It's like it doesn't understand at all these libraries.

Are you really supposed to share libraries between compilers? I'm sure I had read somewhere that this is something that cannot be done (different formats).



My build output is the following:
