By the way, which version of 4.8 is it ?

4.8.7

Did you check which mkspec gets selected when configuring Qt ?

no

[magguz]

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!
