Change App Icon (on the desktop)

yass1213

i ve created an rc file named icon.rc which contains
icon.rc:
#include <windows.h>
IDI_ICON1 ICON DISCARDABLE "MSlogo.ico")

the icon.rc file and the image.ico are on the same project directory(where source and header files )

In my Cmake file i got these changes :

set(CMAKE_RC_FLAGS "${CMAKE_RC_FLAGS} -DWin32Icon=IDI_ICON1")

set(app_icon_resource_windows "${CMAKE_CURRENT_SOURCE_DIR}/icon.rc")

add_executable(jarinDenfant3
${PROJECT_SOURCES}
listeeleve.h listeeleve.cpp listeeleve.ui
calendrier.h calendrier.cpp calendrier.ui
payement.cpp payement.h payement.ui

visiteprofile.cpp visiteprofile.h visiteprofile.ui
camera.cpp camera.h metadatadialog.cpp metadatadialog.h
camera.ui

${app_icon_resource_windows}

)

when i try to run the app i got :-1: error: ninja: build stopped: subcommand failed.

@yass1213
First just verify that C:\Qt2\Tools\mingw1120_64\bin\gcc does indeed exist.

i ve added the C:\Qt2\Tools\mingw1120_64\bin\windres.exe to the PATH but in vain the error persestis

I trust you mean you added just C:\Qt2\Tools\mingw1120_64\bin to PATH.

If nobody here knows/gives you an answer, I suggest you Google for

windres.exe: can't popen

This error has popped up occasionally over the years --- going back a decade! --- for installations of MinGW. I'm afarid I think you would have to look through these to see if any apply to your situation.
