Deploying Kanzi applications to QNX

Before you can build a Kanzi application for your target platforms, set up and configure the Kanzi build environment for your target platforms. The build environment includes tools that the Kanzi build system uses to build your application for your target platforms. The Kanzi QNX platform packages are available on request.

Requirements

To build and deploy Kanzi applications to QNX, you need:

Before deploying your Kanzi application to your QNX target device, make sure that device is running the QNX Screen service. See http://www.qnx.com/developers/docs/7.0.0/index.html#com.qnx.doc.screen/topic/manual/cscreen_about.html.

Building Kanzi applications for QNX

SCons runs the SConstruct file in the configuration directory of the platform from which you run the scons command. SConstruct file is the entry point for building the application and contains the information about the Kanzi Engine location and runs these files:

To build Kanzi applications for QNX:

  1. Open the command line in the configuration directory of the platform for which you want to build the Kanzi application (<ProjectName>/Application/configs/platforms/<PlatformName>) and make sure you have the correct environmental variables set. See Setting the Kanzi environment variables.
    For example, to build your Kanzi application for:

  2. Run the scons command with the build parameters for your Kanzi application.

    Syntax scons <library> <type> <name>
    Parameters
    library

    (Optional) the graphics library:

    • ES2 builds the application with OpenGL ES 2.0
    • ES3 builds the application with OpenGL ES 3.0
    type

    (Optional) the build type:

    • Release builds the application with compiler optimizations enabled. The release option builds smaller files than the debug option. Use this option for production purposes. Default value.
    • Debug builds the application with disabled compiler optimizations and contains full debug information you can use with a debugger. The debug option builds larger files and debug applications run slower. Use this option for development purposes.
    • Profiling builds the application with compiler optimizations enabled and links the application against the Profiling build. Use this option when you want to measure the performance of different parts of Kanzi Engine. For example, when you want to find out how much time Kanzi uses on different tasks during application startup, or which parts of the application take a lot of time to run. See Measuring application performance.
    name (Optional) the name of the project
    Examples 

    // Builds the application with the default settings as specified
// in config.py and SConstruct configuration files.
scons
    // Builds the debug version of the application.
scons debug
    // Builds the debug version of the application with the
// OpenGL ES 3.0 graphics library from the Kanzi Studio
// project named MyProject.
scons ES3 debug MyProject

    Scons builds the Kanzi application source code and binary files in the <ProjectName>/Application/output directory.

Deploying Kanzi applications to QNX

To deploy Kanzi applications to QNX:

  1. Build your Kanzi application for QNX. See Building Kanzi applications for QNX.
  2. Connect your QNX device to your computer.
  3. From the <ProjectName>/Application/output directory copy to your QNX target device:
  4. On your QNX target device open the command line and add execution rights for your Kanzi application on that device:
    // Adds execution rights on the QNX target device
// for the Kanzi application called MyApplication.
chmod 755 MyApplication
  5. On the command line start the application on your QNX target device:
    // Starts the Kanzi application called MyApplication.
./MyApplication
