Building QT 6.2.2 for iOS

Posted by | iOS, Mac OS X, QT |

I built QT 6.2.2. for MacOS first and then configured QT 6.2.2 for iOS as follows:

./configure -c++std c++20 -opensource -confirm-license -no-openssl -securetransport -DQT_NO_EXCEPTIONS=1 \
  -platform macx-ios-clang -release -qt-host-path /usr/local/Qt-6.2.2 -prefix /usr/local/Qt-6.2.2-ios \
  -skip qt3d -skip qt5compat -skip qtactiveqt -skip qtcharts -skip qtcoap -skip qtconnectivity \
  -skip qtdatavis3d -skip qtdoc -skip qtlottie -skip qtmqtt -skip qtnetworkauth -skip qtopcua \
  -skip qtserialport -skip qtpositioning -skip qtquicktimeline -skip qtquick3d -skip qtremoteobjects \
  -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtvirtualkeyboard -skip qtwayland \
  -skip qtwebchannel -skip qtwebengine -skip qtwebview

Building QT 6.2.2 for MacOS – Part 2

Posted by | iOS, Mac OS X, QT |

In my previous post I described my first attempt to built QT 6.2.2 for MacOS. Probably my mistake was that I did not switch to full XCode with the command:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

and that I used the configuration script with a wrong syntax and missed -- in the command line. Probably the following configuration can be a step to a right direction:

./configure -c++std c++20 -opensource -confirm-license -no-openssl -securetransport -DQT_NO_EXCEPTIONS=1 \
  -skip qt3d -skip qt5compat -skip qtactiveqt -skip qtcharts -skip qtcoap -skip qtconnectivity \
  -skip qtdatavis3d -skip qtdoc -skip qtlottie -skip qtmqtt -skip qtnetworkauth -skip qtopcua \
  -skip qtserialport -skip qtpositioning -skip qtquicktimeline -skip qtquick3d -skip qtremoteobjects \
  -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtvirtualkeyboard -skip qtwayland \
  -skip qtwebchannel -skip qtwebengine -skip qtwebview \
  -- -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64"

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:

Reducing the size of QT Android libraries

Posted by | Android, QT |

Tried to reduce the size of the QT Android libs by separating debug info with -separate-debug-info option and skipping the modules I do not use:

“Server certificate verification failed” error with command line Git client

Posted by | Ubuntu |

Some guy described the same situation about 10 years ago on stackoverflow.com and there was another discussion about 7 years ago.

First I did:
