When try to running my Qt execution program, I have error message like “the program can’t start because QtCored4.dll is missing…”
The Qt file with “…d..” is a debug file requirement.
This error showed, because we compile our code in Debug mode. We need to change our *.pro file to make Qt Compile in Release mode. Please add this line :
CONFIG += release
and compile our code again with command “qmake” and “make”
This method will change our Qt Compile in release mode.
