FYI, the msys2 compilation approach is not working

["Wang, Andrew via Tech-talk" <tech-talk at aps.anl.gov>]

Hi all,

 

I’m following the instructions on this webpage for installing EPICS using msys2.

 

Everything worked fine up until the “Download and build EPICS Base” section. After running “export EPICS_HOST_ARCH=windows-x64-mingw”, I get the following errors. Do you suggest that I potentially change the architecture to windows-x64, rather than windows-x64-mingw?
