After several days of research, I found the problem again.
Compiled by QT creatorProgramUnder the project folder, there will be a debug folder with the program's. EXE executable file. However, QT creator uses dynamic links by default, which means the executable program needs the corresponding. dll file during runtime. When we click the generated. EXE file, we may first display"The mingwm10.dll is not found, so the application cannot be started. Re-installing the application may fix this problem.." The mingwm10.dll file is missing.
To solve this problem, we can put the corresponding. dll file into the system. In the bin folder under the QT file in the installation directory of QT creator (I installed it on disk D, so the path is D:/QT/2010.02.1/QT/bin ), all related information can be found. DLL file. FindMingwm10.dllFile,Copy itC:/Windows/SystemFolder. The following prompt shows what DLL files are missing. You can solve them like this.
