How to stop a program compiled with MinGW (g++) from opening a console window in windows

I compiled a program using MinGW g++. When I run it, it opens a console window in addition to the main application window. What's t开发者_Python百科he compiler flag to stop this?

I just add -mwindows to linker flags.

I believe the compiler switch for that is -Wl,-subsystem,windows.

The -Wl,<options> switch passes <options> to the linker. The -subsystem switch tells the linker which system to target when generating the executable.
