After several hours of playing sounds my iOS app crashes and the QT Creator displays the following stack trace:

Building QT6.4 on Windows for Android with OpenSSL and clang 12

Posted by | Android, QT, Windows | Tagged |

My mistake was that while building QT6.4 on Windows for Android I tried to set OPENSSL_ROOT_DIR as an environment variable that doesn’t take an effect. Now I set it as an argument:

C:\dev\build\qta
  
set "CMAKE_ROOT=C:\dev\PFiles\cmake-3.24.2-windows-x86_64\bin"
set "NINJA_ROOT=C:\dev\PFiles\ninja-win"
set "PERL_ROOT=C:\dev\PFiles\Strawberry\perl\bin"
set "MINGW_ROOT=C:\dev\PFiles\x86_64-12.2.0-release-win32-seh-rt_v10-rev0\mingw64\bin"
set "PYTHON_ROOT=C:\dev\PFiles\Python35"
set "JDK_ROOT=C:\dev\libs\jdk-19\bin"
          
set PATH=C:\WINDOWS\system32;C:\WINDOWS
set PATH=%CMAKE_ROOT%;%PATH%
set PATH=%NINJA_ROOT%;%PATH%
set PATH=%MINGW_ROOT%;%PATH%
set PATH=%PERL_ROOT%;%PATH%

OpenVPN in a Docker container

Posted by | Ubuntu | Tagged , |

Run a docker container:

export MY_IP=$(curl -s https://api.ipify.org)

sudo docker run -it --rm --cap-add=NET_ADMIN -p 1194:1194/udp -e HOST_ADDR=$MY_IP --name dockovpn alekslitvinenk/openvpn

or

sudo docker run -it --rm --cap-add=NET_ADMIN -p 1194:1194/udp -e HOST_ADDR=$MY_IP --name dockovpn alekslitvinenk/openvpn -v openvpn_conf:/opt/Dockovpn_data

to persist generated files in volume storage.

Type Ctrl+P then Ctrl+Q to turn interactive mode to daemon mode.

Determine its IP address:

sudo docker ps
sudo docker inspect dockovpn | grep IPAddress

Building QT6.4 with OpenSSL for Windows – iteration #2

Posted by | QT, Windows | Tagged |

Install build tools, build OpenSSL as described in my previous post, extract QT sources with Bash:

tar -xf ../distrib/qt-everywhere-src-6.4.0.tar.xz

Configure QT as follows:

cd C:\dev\build\qt
 
"C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Auxiliary\Build\vcvarsall.bat" amd64
     
set "CMAKE_ROOT=C:\dev\PFiles\cmake-3.24.2-windows-x86_64\bin"
set "NINJA_ROOT=C:\dev\PFiles\ninja-win"
set "PERL_ROOT=C:\dev\PFiles\Strawberry\perl\bin"
     
set PATH=%CMAKE_ROOT%;%PATH%
set PATH=%NINJA_ROOT%;%PATH%
set PATH=%PERL_ROOT%;%PATH%
set PATH=C:\dev\PFiles\Python35;%PATH%
     
rem Check if the tools are in PATH
where perl.exe
where python.exe
where cmake.exe
where ninja.exe
     
set MY_INSTALL_PATH=C:/dev/libs/Qt6.4/windows
