"License file does not contain proper license key." on configure

hanvyj

I'm just being an idiot... I managed to miss updating some of the projects using the extension. Ignore me!

Argh, 6791 errors! They're all link errors:

Error LNK2001: unresolved external symbol "__declspec(dllimport) public: void __thiscall QWidget::setWindowTitle(class QString const &)" (_imp?setWindowTitle@QWidget@@QAEXABVQString@@@Z) C:\Users\MOD_3\Documents\Visual Studio 2010\Projects\Dems\dems\solution\projects\demshmi\dems_Hmi.obj

In here (https://forum.qt.io/topic/28526/qt5-linker-error-for-vs2012-solved/3) you say the solution is to

"include a line like
@
QT += widgets
@"

in the "pro" file. I didn't have a pro file so I created one with the extension. The error remains and I do have the line:

QT += core multimedia sql opengl widgets gui

If you are using the Qt VS AddIn module you can follow the instructions here

I'm pretty sure that's how I've got it set up:

I keep reading that I need to run "qmake" does this mean literally run the qmake.exe in the bin directory?

SGaist

It's been a long time since I used the AddIn, I don't remember what would be the equivalent of rerunning qmake. However, doing a full rebuild (maybe nuke the build folder entirely) might do the trick.

Tried to do a nuke, didn't seem to work.

Finally tracked it down! I think. I needed to add:

C:\Qt\Qt5.5.0\5.5\msvc2010\lib\Qt5Widgets.lib

to the additional dependencies of the input section of the "linker". I have some library projects that seem to be having issues and there's no "linker" section though.

SGaist

Thought that the plugin would have take care of updating it for you…

Everything is working now ?

hanvyj

Almost! Thank you for the help.

I got it to build in release mode, but strangely when I change to debug (there's a runtime error) I 'm back to square one, with it unable to find the QT includes! I checked and the (QTDIR) is the correct path this time:

Error C1083: Cannot open include file: 'QApplication': No such file or directory C:\Users\User\Documents\Visual Studio 2010\Projects\Project\file.cpp

Edit I think I only did all those changes to the release build properties! Will change the debug to match and fingers crossed everything should work.

I need to build the IBASE SQL drivers, but I've no idea how to download the source. I created a new post though as this one is getting very long and not much to do with the title.

Thanks for the help, I got it to build at last.

SGaist

Indeed, you could even set this one to solved since you have things working :)
