Building Qt for Qualcomm Snapdragon 8155P Board on Windows 10
Having Green Hills INTEGRITY and Qualcomm development environments setup is a required before proceeding. See Installing Platform Dependencies.
Creating a batch script for Windows 10
To set up the development environment for Qt for INTEGRITY, build Qt from the sources for the Qualcomm Snapdragon 8155P board. Before building Qt for INTEGRITY, set up build environment. Here a batch script to automate that, as it needs to be done before each build.
For Windows 10 create a new batch script setEnvironment.bat, and save it under your home folder. Add the following export variables to the script:
@echo off set PATH=%PATH%;C:\ghs\comp_202014 set INTEGRITY_DIR=C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\integrity set INTEGRITY_BSP=platform-sa8155 set INTEGRITY_BUILD_TARGET=chk set QC_MULTIMEDIA_INC_DIR=C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\qc_bsp\include\amss\multimedia set GL_INC_DIR=C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\qc_bsp\AMSS\multimedia\graphics\include\public set GL_LIB_DIR=C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\qc_bsp\out\rel\libs\base;C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\qc_bsp\out\rel\libs\multimedia\display;C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\qc_bsp\out\rel\libs\multimedia\graphics;C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\qc_bsp\out\rel\libs\platform\;C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot\apps\ghs_apps_proc\qc_bsp\AMSS\multimedia\graphics\opengl\esx\build\integrity\prebuilt\ set TARGET_ROOT_PATH="C:\Users\user\ghs_pack\es7_dev_env\hlos_dev_boot"
These export paths assume you have used the C:\ghs\comp_202014 and C:\Users\user\ghs_pack\* installation directories while installing the MULTI IDE and INTEGRITY (see Installing Platform Dependencies). If you have not used the default directories, adjust the export paths accordingly.
To initialize your build environment, run the following command in a Windows CMD terminal:
setEnvironment.bat
Note: Run this command in the Windows CMD terminal every time you build Qt, or use the qmake or CMake build systems.
Getting Qt sources
You can download the Qt source code from your Qt Account.
You can also get the Qt sources from the Git repo, see Getting source code.
Note: Qt sources version must be 6.2 or later.
Note: Qt modules supported by Qt for INTEGRITY are listed in Supported Qt Modules.
Building Qt Desktop for cross-compiling tools usage
The cross-compiling Qt requires a host build of Qt being available. During the build, tools such as moc, rcc, qmlcachegen, qsb, and others, are invoked from there. For more detailed information please read Cross-compiling Qt.
Run the following commands for Windows 10 Host build:
mkdir hostbuild cd hostbuild/ C:/Users/user/qt5/configure -nomake tests -nomake examples -release -prefix C:/Users/user/hostbuild cmake --build . --parallel 6 cmake --install .
Creating a toolchain file for INTEGRITY
To cross-compile a project with CMake, one must specify a toolchain file. This CMake-language file sets the right values for the platform name, the compiler/linker used, and a whole bunch of other toolchain-specific things. For Integrity build on Windows 10 create a toolchain.cmake file with following content:

Configure Qt for the Qualcomm Snapdragon 8155P board using these following commands: Windows 10 HOST requires follow configure line:
mkdir targetbuild cd targetbuild/ cmake C:/Users/user/qt5/ -DQT_HOST_PATH=/c/Users/user/hostbuild/qtbase -DCMAKE_TOOLCHAIN_FILE=/c/Users/user/ghs_pack/es7_dev_env/hlos_dev_boot/toolchain_integrity.cmake -DQT_QMAKE_TARGET_MKSPEC=devices/integrity-armv8-SA8155P -DBUILD_qtdoc=OFF -DBUILD_qttranslations=OFF -DFEATURE_printdialog=OFF --debug-trycompile -DFEATURE_dbus=OFF -DFEATURE_dnslookup=OFF -DFEATURE_glib=OFF -DFEATURE_system_pcre2=OFF -DFEATURE_sql_mysql=OFF -DQT_FEATURE_harfbuzz=OFF -DFEATURE_pkg_config=OFF -DUNIX=ON -DCMAKE_HOST_WIN32=ON -GNinja -DCMAKE_INSTALL_PREFIX=/c/Users/user/targetbuild/
Note: INTEGRITY supports only static Qt builds.
Note: QT_HOST_PATH variable introduced in Qt 6. When cross-compiling, this must be set to the install location of Qt for the host platform. It is used to locate tools to be run on the host (moc, rcc, androiddeployqt, and so on).
Building Qt for INTEGRITY
Build Qt by calling cmake in the terminal. You can run cmake with as many cores on your host machine as you desire. In our example we use six cores:
cmake --build . --parallel 6
Installing Qt
If you have not used the configure option -prefix $PWD/qtbase in Configuring Qt, run the following commands in a terminal:
cd <Qt installation directory> cmake --install .
If you have used the configure option -prefix $PWD/qtbase, you can use Qt from the build directory, without running the cmake install command.
Qt is now configured and built for the sa8155 board.
