Procedural entry point not found

[dittelund]

I tried to update my Qt project from 5.13.2 to 5.15.0 but now when I build i get the following error:

Der Prozedureinsprungpunkt "??4QLinearGradient@@QEAAAEAV0@$$QEAV0@@Z" wurde in der DLL "C:..\debug\plplot.dll" nicht gefunden.

Roughly translated:

The procedural entry point "??4QLinearGradient@@QEAAAEAV0@$$QEAV0@@Z" was not found in the DLL "C:..\debug\plplot.dll".

Does anyone have a clue what the problem is?
Current Plplot version is 5.14.0

Thanks in advance

@dittelund Delete build folder, run qmake and build.
You probably have build artefacts built with 5.13.2

@jsulm hm that does not seem to work :/
There is still the same error.
I still have 5.13.2. installed in parallel, just changed the environment path variables. Is that a problem?

@dittelund said in Procedural entry point not found:

environment path variables

Which exactly and how/why do you set them?

[dittelund]

A Path to the msvc2019 binary files and the QtDir variable to the Qt directory.
