# Building a monolith project

This tutorial will guide you through building a monolith INTEGRITY project for a Qt example application. You can select any Qt example application that uses the Supported Qt modules.

Before building the monolith INTEGRITY project, prepare your build environment by running the `setEnvironment.sh` script. For more information about the script, see Creating a set environment shell script.

     source ~/setEnvironment.sh

## Building the Qt application

- `CMake` tool

  To build the application against Qt6 using CMake, run the following commands in a terminal:

       <Qt installation path>/bin/qt-cmake <Qt example application path>/CMakeLists.txt
       cmake --build .

  Where, `qt-cmake` is the wrapper script that calls CMake to configure your project with appropriate include paths.

- `qmake` tool

  To build the application against Qt6 using qmake, run the following commands in a terminal:

       <Qt installation path>/bin/qmake <Qt example application path>/application.pro
       make

## Building a monolith project

The board support package (BSP) for the Qualcomm Snapdragon 8155P board provides a build script to create a set of images for board partitions:

     /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/apps/ghs_apps_proc/build_ghs.sh

Add a Qt application to a build by adding it into the monolith-service.int file:

- Start MULTI Launcher.
- Select Components > Open Project Manager.
- Select the project file default.gpj under the /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/apps/ghs_apps_proc/qc_bsp directory:

  MULTI application shows a window with a list of project files from the chosen folder.

- Select Open.

In the MULTI Project Manager view, you should see a tree structure of the opened project.

Go through the `default.gpj` sub projects:

- Select target.auto vmm-adp-no-gvm-sa8155.gpj > vvm-adp-gvm-ref.gpj > monolith-service.gpj. You can observe the project structure and edit a project's files.
- Select monolith-service.int

  Selected monolith-service.int file is highlighted in the project tree.

- Right-click on the file, then select Edit from the context menu.
- Add the following lines at the end of the file.

       AddressSpace
       Name    myappname
       Filename    /path/to/your/app/executable
       MemoryPoolSize 0x2700000
       Language    C++
       HeapSize    0x90000

       Task Initial
       StackSize    0x80000
       StartIt    false
       EndTask
       Extendedmemorypoolsize 0x300000
       EndAddressSpace

  Note: Replace </path/to/your/app/executable> with a path to your application executable.

- Run the build script.

       bash /work/ghs/sa8155/es7/es7_dev_env/hlos_dev_boot/apps/ghs_apps_proc/build_ghs.sh

Your monolith project is now ready to be flashed on to the board.
