    Do you have the same behavior if you build a default application ?

        This problem is not solved, and occasionally occurs for no reason. The size of EXE file increases with the number of times creator is started

            Hi

            If you delete teh build folder and rebuild all. then what size has it ?

              After I delete the build folder, clean up the project and rebuild, the size is increased compared to the previous one. The Qt version is 5.15.2

                so you clean the folder and rebuild
                If you do it again, this time the exe size is bigger ?

                    and you go and delete the exe ?
                    not just use the menu clean build folder ?

                        Then its a bit odd as a clean build should be same size unless you add something new.

                          The normal EXE file is only 2M, and the abnormal one is 100M

                              I think it may be the creator's problem

                                @duncan98 I am certain it has nothing to do with Qt Creator. Starting Qt Creator will not change an executable. Creator is not a C++ compiler; it is an editor that can launch a make process to build your executable for you. The compiler and linker are what produce the executable. In your case, this a GCC version. Producing the executable is not connected to running the executable.

                                The ways a Windows executable file can grow is:

                                • You put more code, or embedded resources, in it.
                                • You build a version with debug symbols, which will be a bit larger (but not usually an order of magnitude)
                                • You build a version with different compiler optimisation options.
                                • You change the compiler; different compilers will produce different sized results.
                                • Some external process, that is neither the compiler nor the running executable, opens the file and appends to the executable.

                                If you want to support your claimed behaviour with some evidence:

                                • Delete your build folder
                                • Verify that your target executable (wms.exe) does not exist.
                                • Build your application
                                • Post the entire content of the Qt Creator compiler output panel (copy and paste the text not a partial screen shot)
                                • Execute "dir wms.exe" in the build folder and post the result
                                • Delete the executable
                                • Build your application
                                • Post the entire content of the Qt Creator compiler output panel (copy and paste the text not a partial screen shot). Note that this should not include calls to compile C++ source, only a linker call.
                                • Execute "dir wms.exe" in the build folder and post the result

                                  Thank you for your explanation. It should be related to the compiler. But something more strange happened. I uninstalled and reinstalled QT, and now I can't start it 😂

                                          @duncan98 I am certain it has nothing to do with Qt Creator. Starting Qt Creator will not change an executable. Creator is not a C++ compiler; it is an editor that can launch a make process to build your executable for you. The compiler and linker are what produce the executable. In your case, this a GCC version. Producing the executable is not connected to running the executable.

                                          The ways a Windows executable file can grow is:

                                          • You put more code, or embedded resources, in it.
                                          • You build a version with debug symbols, which will be a bit larger (but not usually an order of magnitude)
                                          • You build a version with different compiler optimisation options.
                                          • You change the compiler; different compilers will produce different sized results.
                                          • Some external process, that is neither the compiler nor the running executable, opens the file and appends to the executable.

                                          If you want to support your claimed behaviour with some evidence:

                                          • Delete your build folder
                                          • Verify that your target executable (wms.exe) does not exist.
                                          • Build your application
                                          • Post the entire content of the Qt Creator compiler output panel (copy and paste the text not a partial screen shot)
                                          • Execute "dir wms.exe" in the build folder and post the result
                                          • Delete the executable
                                          • Build your application
                                          • Post the entire content of the Qt Creator compiler output panel (copy and paste the text not a partial screen shot). Note that this should not include calls to compile C++ source, only a linker call.
                                          • Execute "dir wms.exe" in the build folder and post the result
