Recently, I'm having some problem compiling cpython from Visual Studio 2019. I'm able to compile using the build.bat script. I'm using Visual Studio 2019 for about 2-3 months now for compiling and developing cpython. But unfortunately, some error occurs. While compiling cpython from Visual Studio 2019 the asdl_c.py, if I remember correctly, raises an exception that it was passed no arguments and therefore the build fails. After I compile cpython using build.bat script I'm able to build and rebuild cpython from Visual Studio 2019 without facing any problem for 2-3 days. Then again the error occurs. Can anyone explain to why this is happening? Or is this a bug in cpython?

It's almost certainly not a bug in CPython. But you haven't even shown us what the error is, so it's impossible to say. What error are you seeing?

I'm not able to reproduce the error right now. I think I forgot to clean all object files and other stuff created during compilation and therefore was witnessing the error during rebuilding. I'm closing this issue for now. If I come across this error in the future I'll reopen this issue and attach a screenshot of the error.

Okay, and good luck!
