I seem to be in dll hell. I have installed qt4.4.1, commercial edition, onto a PC with Visual Studio 2005. I also installed the most recent version of qwt. (5.1.1)
When I try to run the demo apps in qwt, (and when I clean and rebuild apps that I have written--they also use qwt)--I get
"The Procedure entry point ?setAlignment@@Layout@@... could not be located in the dynamic link library qtguid4.dll"
I have searched my entire hard drive, and there is only one qtguid4.dll on the disk. When I change its name, I get an an error that says windows can't find the dll at all, so that does appear to be the one I'm using--and its new, its the one that came with the qt4.1.1 install.
At one point, I did have earlier versions of qt on the machine, but I have cleaned them all off and re-installed ONLY the 4.1.1 version. I have reinstalled and rebuilt qwt, and my apps. I can't get away from the entry point error
any ideas? All of my apps work (on a different machine) under QT 4.2.3
