Hello, the Windows Cygwin Toolchain for PX4 has been officially discontinued, so there may not be a good solution for such issues. I recommend using: RflySim：A Toolchain For The Development, Testing, And Evaluation Of An Unmanned Aerial System (UAS) Based On PX4。
RflySim is completely free and can be used directly on Windows after installation. It comes with built-in tools like QGroundControl (QGC), PX4 source code, WSL compiler, and more. It includes most of the common software used for drone development!
For more detailed information, please visit https://doc.rflysim.com . The basic and advanced trial versions of RflySim can be obtained by providing your email address through the download link at https://rflysim.com/download .
