Thirumalai-Shaktivel commented 1 year ago

Thanks, @liudonghua123 for trying out LPython!! Currently, we don't support building the LPython using minGW, can you try MSVC? If MSVC is already installed on your system, try calling the following in the mini forge command prompt: call "C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\Tools\VsDevCmd" -arch=x64 (See: https://github.com/lcompilers/lpython#windows).

Or you can also try installing lpython using conda on Windows and see if that helps.

liudonghua123 commented 1 year ago

Yes, I forget to execute call "C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\Tools\VsDevCmd" -arch=x64.

And I also got the following errors after I use MSVC build tools even I execute chcp 65001.
