Qt LNK2019: unresolved external symbol "__declspec(dllimport)..." VTK

[AnaM]

Hello! Thank you!

Yes that example! Any help?

[SGaist]

I missed something the first time I read your thread. Visual Studio 2010 ? Did you build VTK yourself with that version of VS ?

[mrjj]

Hi
To add to @SGaist ,
In Creator, you also have selected VS2010 as compiler ?

[AnaM]

Hello!

I build VTK myself with VS! I build with Release mode, should I build with Debug mode instead?

How do I select VS as compiler in Qt?

Thank you very much!!

[AnaM]

@jsulm Yes, The VS is selected as the compiler.
Maybe the problem is the build mode?(release/debug)?

Thank you again

[SGaist]

I might be insisting but do you have everything build with the same version of MSVC ? Same architecture ?

[AnaM]

@SGaist Yes, everthing was build with MSVC same version.

[SGaist]

Wouldn't you be missing the vtkWidgets library in your .pro file ?

[AnaM]

@SGaist No.
Maybe it's because I am building my project in VS 64 bit and Qt only detects VS compiler 32 bit?
How can I make Qt work with 64 bit?

Thank you!!

[SGaist]

You have to install a 64bit build of Qt. You can't mix and match libraries of different architectures.

[Edit: fixed wording... Thanks @jsulm]

@SGaist said in Qt LNK2019: unresolved external symbol "__declspec(dllimport)..." VTK:

You can mix

You can't mix :-)
