This tutorial shows how to build and debug a Qt 5 app For Raspberry Pi using a cross-compiled Qt build. Before you begin, follow this tutorial<\/a> to create a cross-compiled build of the Qt framework.<\/p>\n

    \n
  1. Start Visual Studio. Select File->New->Project and choose the VisualGDB Linux project wizard:\"00-qted\"<\/a><\/li>\n
  2. Select Create a new project -> Applications -> Use Qt:\"01-prj\"<\/a><\/li>\n
  3. On the next page select “Build the project locally” and specify your Raspberry Pi cross-toolchain and the connection settings:\"02-comp\"<\/a><\/li>\n
  4. Click the link at the bottom of the page to configure the Qt settings:\"03-configure\"<\/a><\/li>\n
  5. Select “Use previously configured Qt tools” and specify the path to the qmake<\/strong> binary and the specs directory used when building the Qt framework as described in this tutorial<\/a>:\"04-dirs\"<\/a><\/li>\n
  6. Press “Finish” to create your project. Then build it with Ctrl-Shift-B:\"05-build\"<\/a><\/li>\n
  7. Press F5 to start debugging and look at the screen connected to the HDMI port on your Raspberry Pi. If you are using the Embedded Qt build (non-X11), the simple main window used in the example will be automatically stretched to the entire screen:\"06-button\"<\/a><\/li>\n
  8. Set a breakpoint in the ButtonClicked() method and click the button on the Raspberry Pi screen. The breakpoint will get triggered:\"07-bkpt\"<\/a><\/li>\n
  9. Resume your program by pressing F5 and observe the “Hello, world” message. If you are using the Qt-embedded build that does not use X11 and has no window manager, the message box will have no frame around it:\"08-msgbox\"<\/a><\/li>\n
  10. You can edit various settings of your project by right-clicking on it in Solution Explorer and selecting “VisualGDB Project Properties”:\"09-props\"<\/a><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
