Trouble compiling Qwt 5.1.1 with Qt 4.4.0

I get a lot of unresolved external symbol errors when trying to compile 
5.1.1 with qt 4.4.0. What can I try to solve this?

I had to recompile qt commercial because of application linking errors 
with VS.NET 2008. Recompiling solved this issue. Is this now causing 
issues with Qwt?

Thank you!

I have Qt4.4.0 commercial, recompiled (as static lib) under VC++2005.
Qwt5.1.1 compiles and links nicely with that.

Don't know if that helps you.

Rainer

When compiling 5.2 SVN I get lot of errors like this:

This problem has already been reported here: 
http://sourceforge.net/tracker/index.php?func=detail&aid=1948333&group_id=13693&atid=113693

If you tell me where the previous explicit instantiation happens ( I don't use 
Windows myself) I will try to fix it.

Re: Trouble compiling Qwt 5.1.1 with Qt 4.4.0

Hello! Thank you very much for your answer. Yes, the first time I wrote about 5.1.1, but I tried 5.2SVN because 5.1.1 did not link. I tried now again and *miracle* now it links. But when I try to load plugin in VS 2008 I get message:

The plugin 'C:/Program Files/Trolltech/Qt VS Integration/plugins/qwt_designer_plugin5.dll' uses incompatible Qt library. Expected build key "Windows msvc release full-config", got "Windows msvc release full-config no-stl"

Does that mean I must recompile Qt with STL enabled? So does Qwt require STL enabled?

In regard to 5.2SVN: how to tell you where previous explicit instantiation happens?

Thank you again,
Igor

By looking into the code. 

In the meantime I did this myself and found a QVector<QPointF> declaration in 
qvector.h. So I disabled the declaration in the the Qwt header for Qt >= 4.x.

Please check 5.2 SVN ( = trunk ) on Windows and let me know if this fixes the 
problem.

Re: Trouble compiling Qwt 5.1.1 with Qt 4.4.0

Hello,

trying to compile newest 5.2 SVN, now I dont get compile messages anymore. But there are a lot of linker messages like this:

qwt_designer_plugin.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall QwtKnob::fontChange(class QFont const &)" (?fontChange <at> QwtKnob <at> <at> EAEXABVQFont <at> <at> <at> Z)

I want to ask you again what I already wrote in previous post (in regard to 5.1.1):

when I try to load plugin in VS 2008 I get message:

The plugin 'C:/Program Files/Trolltech/Qt VS Integration/plugins/qwt_designer_plugin5.dll' uses incompatible Qt library. Expected build key "Windows msvc release full-config", got "Windows msvc release full-config no-stl"

Does that mean I must recompile Qt with STL enabled? So does Qwt require STL enabled?

Thanks,
Igor

Sounds like a problem on your side. At least QwtKnob::fontChange hasn't 
changed since decades.

No, it doesn't. Are you sure, that you have built the Qwt with the same Qt 
environment ?

I know that there is not problem with this function because I get a LOT of similar messages. And I also dont understand why this is not working. What could be wrong?

No, it doesn't. Are you sure, that you have built the Qwt with the same Qt environment ?

Well, I have built Qt that is now active and being used by Visual Studio Integration. Qwt Designer plugin however does not load, message says:
Expected build key "Windows msvc release full-config", got "Windows msvc release full-config no-stl".

Both are release, the only difference that I see here is in STL parameter. Maybe Designer needs STL built into Qt to launch Qwt plugin. However, I think the only option here is to try to rebuild Qt without "no-stl" parameter.

For me it looks like Qwt has been built with STL support and now you want to 
run it against a Qt library without STL support. Instead of rebuilding the Qt 
library I recommend to check why Qwt has been built with STL support.

In my environment ( Linux/gcc ) you find the QT_NO_STL define in 
QtCore/qfeatures.h. I would expect, that it is enabled in your Qt headers and 
should be included by the Qwt headers ?

Re: Trouble compiling Qwt 5.1.1 with Qt 4.4.0

For me it was easier to rebuild Qt with STL enabled. I then recompiled Qwt too. And now Qwt Designer plugin works inside Visual Studio! :-D

I only have 1 more problem when running my test program. If I open a window that has some Qwt controls included and then close my whole program, then test program crashes (while closing). It says it is because of heap corruption. What could cause that? Did I forget to do something?

Do you use a debug Qwt version with a release Qt version or vice versa?
