An attempt to build static QT for Android

Posted by | Android, QT |

qtbase\cmake\QtPlatformAndroid.cmake contains this:

# Ensure we are using the shared version of libc++
if(NOT ANDROID_STL STREQUAL c++_shared)
    message(FATAL_ERROR "The Qt libraries on Android only supports the shared library configuration of stl. Please use -DANDROID_STL=\"c++_shared\" as configuration argument.")
endif()

and looks like -static-runtime works only for Windows.

I added -c++std c++20 -static -no-openssl to the configuration and removed -separate-debug-info:

How I fixed “CMake configuration has no path to C++ compiler” in QT Creator

Posted by | QT |

CMake did not work and there was a yellow triangle at the left side of MSVC2019 kit name:

I fixed this buy changing C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat with C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsx86_arm64.bat.

Using QML_ELEMENT with CMake

Posted by | QML, QT |

There is an example of using QML_ELEMENT in qt5\qtdeclarative\examples\quick\scenegraph\openglunderqml and qt_add_qml_module in CMake:

qt_add_qml_module(openglunderqml
    URI OpenGLUnderQML
    VERSION 1.0
    QML_FILES main.qml
    RESOURCE_PREFIX /scenegraph/openglunderqml
    NO_RESOURCE_TARGET_PATH
)

In QML it imports the module:

import OpenGLUnderQML 1.0

Building QT 6.2 for Windows with MSVC2019

Posted by | Android, QT, Windows |

I cloned QT repository:

git clone --recursive https://code.qt.io/qt/qt5.git --branch v6.2.0
cd qt5

Looks like the command below is not required:

./init-repository --module-subset=all

because it prints:

Will not reinitialize already initialized repository (use -f to force)!
