When compiling under msys2, I encountered the following error:

How should this problem be eliminated?

Hi @dingzex . I am not very familiar with msys2/mingw64, but running VTR and most open-source tools on windows environments are notoriously painful. Your problem seems to be caused by a definition confliction in a system header file and ABC's included header file. I would recommend you try to use virtualbox to run a full linux OS, rather than running on a windows software which offers much less compatibility than a virtual OS.

Thank you for your reply .

According to what you said, I installed it on the virtual machine. It seems that the installation succeeded, but I found the following problems:

an you give me a hint?

I tested three versions of the compiled operating system today: ubuntu v16. 0.4 failure ubuntu v18. 0.4 failure Ubuntu V20 succeeded It can be generated and simulated normally.

Thank you!
