My attempt to build OpenSSL for Android on Windows

Posted by | Android, Windows | Tagged |

I tried to build OpenSSL for Android with the following commands in Windows Command Prompt:

cd C:\dev\repos\openssl-1.1.1r

set MY_NDK_DIR=C:\Users\dmitr\AppData\Local\Android\Sdk\ndk\23.1.7779620

set MY_CLANG_DIR=%MY_NDK_DIR%\toolchains\llvm\prebuilt\windows-x86_64\bin

set MY_PERL_DIR=C:\dev\PFiles\Strawberry\perl\bin

set PATH=%MY_CLANG_DIR%;%MY_PERL_DIR%;%PATH%

rem set "MY_ANDROID_BUILD_ABI=x86"

Dramatically annoying crash at std::thread and std::mutex destructors on Android

Posted by | Android, QT |

It is a long story that started here about 2 years ago. My first understanding was that it is a QT bug that was not fixed within this 2 years, of course (as a rule or usually), but a couple weeks ago I noticed that a similar crash happens on Samsung Galaxy devices:

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

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)!
