Question:

Put the enigma virtual box packaged exe to another computer for use, and an error will be reported when opening the EXE: cannot load library qt5core DLL
(in fact, the library qt5core.DLL is included when using enigma virtual box)

reason:

This is not the lack of qt5core DLL , nor is there a problem with this library. Because [problem solving] the code cannot be executed because libgcc_s_dw2-1.dll, libwinpthread.dll and libstdc + ± 6.dll cannot be found. Reinstallation may solve this problem. This problem is caused by the lack of libgcc_s_dw2-1.DLL, libwinpthread.DLL, libstdc + + - 6.dll , but the error cannot be reported after packaging load library Qt5Core.DLL, the analysis may be because qt5core DLL depends on the above libraries to run.

Solution:

From Qt5 12.0\5.12.0\mingw73_64\bin (different versions and different directories) copy the three dynamic libraries libgcc_s_dw2-1.DLL, libwinpthread.DLL, libstdc + + - 6.DLL , and then use the EXE packaged with enigma virtual box to avoid errors.
