The following are instructions for installing Qt and compiling a demo application using the MinGW toolchain:
- Download the Qt 4.8.4 libraries installer here.
- Run the installer. If a warning message about the version of the w32api.h file appears ignore it and continue the installation (my install is version 3.17 and appears to work fine).
- By default, the installer does not add the Qt toolchain to the PATH. Instead, it provides a custom command prompt environment called the "Qt 4.8.4 Command Prompt"; launch this command prompt from the Start menu.
- Now we can try compiling an example; from the Qt command prompt, navigate to C:\Qt\4.8.4\demos\textedit.
- Execute the command qmake; this should generate a makefile.
- Build the example using the command make.
- If everything goes correctly, textedit.exe should now exist in the debug directory; launch the demo application.
That’s it! Your machine is now ready to build Qt apps using MinGw.
