QT Creator Linking issues

[sgrant327]

When compiling and linking, I get the 'unresolved reference' errors pointing at '_imp__' functions.

Being a relative noob at QT Creator, could someone please point me at a good tutorial on utilinzing external libs with QT?

Also, the libs & dlls I have been trying to use are the QT OpenSceneGraph libs & Delta3D libs...

Thanks!

What does Qt Creator have to do with this?

?????

Sorry, a bit confused with THAT question.

I am using QT Creator to develop an app...duh?!

----------------------------------------------------------

This applies to QT (Creator) because I get the unresolved references whenever I try to use external LIBs in the project. I have tried OSGQT, Delta3D for QT, ImageMagick & GraphicsMagick..they all give unresolved reference errors.

I am able to get FreeImage and the Presagis Openflight API libs to play nice....

Just want to know why some work and some don't. If it is a name mangling issue, how do I resolve it?

If it is just my own stupity, then please point me in the right direction...hence the request for some sort of tutorial on using external libs in QT.

So? What does Creator have to do with linking issues?

So far we don't even know what compiler nor project manager you are using.

QT Creator w/QT 4.5.3

mingw32-make.exe

qmake.exe

Attempting to build on WinXP. All I did was install QT Creator and start coding. Nothing special.

How did you add those libs you want to your project?

[sgrant327]

Currently they are added in the PRO file...

LIBS +=

The project I am trying to compile right now is the QOSWidget.

Ok, but what comes after "LIBS +="?

[sgrant327]

OSG_LIBS = -losgText$${D} \
-losgGA$${D} \
-losgFX$${D} \
...
-losg$${D}

LIBS += $${OSG_LIBS}

And what are the undefined references you are getting? Do the classes in the libs contain proper export macros for Windows? Are you sure the linker does actually find the libraries you link against?

[sgrant327]

Not sure, not sure, not sure...

That is why I was asking for some sort of tutorial...

The undefined ref's appear to have the names mangled.

Thant is all I know...
