View Full Version : Setting up Qwt5.1.1

15th October 2008, 14:27

I've searched this forum and saw that a few people have been struggling to get Qwt working. I am basically struggling with two things:

1) I can't get it to load in the Qt Designer. This is due to debug/release libraries being mixed according to the Designer plugin window. I've checked and my Qwt is built in release mode, since all the .pro files load the config in the qwtconfig.pri file, in which I clearly specified that I want release mode (config += release). Now the question: Why does it not work? Is Qwt built using other qt libraries which are perhaps built using debug mode or something like that? (I thought the Qt dll's are built in release mode...)

2) The examples does not run and the give the following error:
"The procedure entry point _Z5qFreePv could not be located in the dynamic link library QtCore4.dll."

But I opened the QtCore4.dll using dependancy walker and that function is indeed in the dll.

I'm Using Qt 4.4.3 and MingW 3.4.2.

Any help with this would be appreciated.

OK, tried it at on my laptop at home, and everything worked fine first time. Designer integration as well as the example programs.

The differences:
Not working - Downloaded archive, Qt 4.4.3
Working - Booked out latest stable release from sourceforge, Qt 4.4.1
