Hello,

This is not your fault, I had never attempted to build Turbo Vision in Cygwin. I'll see what I can do.

Cheers.

Cygwin will not be supported for the time being. If you are on Windows, note that you can also build Turbo Vision with Visual Studio or in WSL.

Thanks for your quickly response! I will try Visual Studio. Thanks a lot and congratulation for your initiative.

Best regards

To build with Visual Studio, just install Visual Studio Community and CMake for Windows, then run CMake from the command line. This is probably simpler than building through the Visual Studio UI.
