Notes
(AI transcribed and summarized)
The speaker, Cristian Adam from the Qt Creator team, presents a project using Cosmopolitan Libc to create a single binary that runs on multiple platforms (Windows, Linux, Mac OS) without modifications. Key points include:
- The project aims to compile once and run everywhere
- Cosmopolitan Libc enables Unix-like behavior on Windows and other platforms.
- The speaker demonstrates a Qt example running on all three platforms using VNC QPA.
- The project faces challenges with CMake and GUI layers, but the speaker is exploring solutions like SDL QPA and Angle project.
- The ultimate goal is to create a usable, cross-platform application with a nice GUI layer.
- The speaker acknowledges the project's complexity and the need for a clear path forward.
This time Windows works and a native VNC Client (build for Linux, Windows, macOS x64 and arm64) is bundled with the affine.exe application. The VNC client is extracted from the application at startup and connects to the localhost:5900 VNC server provided by the cosmopolitan application.
