Did you check which mkpec gets selected when configuring Qt ?

no

I also tried it that way:

https://wiki.qt.io/How_to_build_a_static_Qt_version_for_Windows_with_gcc

But at the step where to modify the file qtenv.bat I don't find such a file in my Qt-folder.

SGaist

This one looks more recent.

This one also doesn't work.

I tried now the tool windeployqt which comes with Qt5, but it seems to work only with Qt5-binaries. It would be enough if I could pack the exe file of my project with the necessary dlls in one folder so it runs on every Windows computer.

SGaist

Then use Dependency Walker to get the dll used by your application and add the necessary plugin if any is needed and you should be good to go.

magguz

The Dependency Walker doesn't work with my exe file. How can I determine instead the necessary dlls?

SGaist

What do you mean by doesn't work ?

magguz

There are many dlls shown by the Dependency Walker. I copied all in a folder with my exe file. After starting the exe now an error occur: "procedure entry point could not be located in dll"

SGaist

Which exactly ?

magguz

it says in the exe file of my project

SGaist

What entry point is missing ?

magguz

it is very cryptical:

_ZNSt7__cxx1112basic_stringlcSt11char_traits.......

When using in google "_ZNSt7__cxx1112basic_string" to search this pops up first https://gcc.gnu.org/ml/libstdc++/2015-03/msg00082.html

I thought you are trying compile with MSVC, but that indicates clearly a MinGW library. The name of that dll is given that the post above.

I found it myself. This dll was missing. Now it works fine! Thanks!
