QwtPlot3D compilation problem

[gutiory]

Hello everyone.

I'm newbie in Qwtplot3D and I have one problem using this library.
For the generation of the dll's I've made the next:

1. Download and unzip the qwtplot3d_0.2.7.zip
2. Execute dsp.bat, which made qmake qwtplot3d.pro
3. Open qwtplot3d.sln with vs2005 and I've built the project in debug and release mode.
4. Created one simple project using an easy example

Until point 4, everything worked great. I've compile without problem. But when I try to execute it, it works in debug mode but not in release.
Can anybody help me?. What am I doing wrong?.

Thanks a lot.

Hiho gutiory!

I hope that you solved your problem until now (when i see the date of your post).
But if not, here is a point that could be the reason:
Windows needs to know explicitly if your project is in "debug XOR release" mode (it's a XOR, not a simple OR).
Windows has problems if you try to mix things up or if you try to make a "debug_and_release" project.
So the solution might be to just exclude the other version in your profile...
Let's say you want to compile a release version, then your pro-file should include following:

...
CONFIG += release
CONFIG -= debug
CONFIG -= debug_and_release
...

...
CONFIG += release
CONFIG -= debug
CONFIG -= debug_and_release
...

To copy to clipboard, switch view to plain text mode 

I had similar problems under windows and that way helped solving them.
Be sure to make a cleanup of older/incompatible object files if you choose to change the debug/release version sometime in between.

Good luck,

PS: I don't know if the "debug_and_release" version works for windows, I tried that at some point and it didn't work for me.
It compiles successfully but one of the two will not execute (if I can remember well enough).
It works under Linux but not with Windows. So try to make 2 versions separately, if you need both variants.

You can't mix libraries built in debug and release mode. So when you want to use qwtplot3d in debug mode you need to have Qt debug libraries as well.
