When attempting to build Epics Base v7.0.2 on Windows 10 using make from msys2 (or other sources) and Visual Studio 2017 Community Edition, this type of error keeps appearing:

epicsTempFile.cpp

c1xx: fatal error C1083: Cannot open source file: '../../src/osi/os/WIN32/epicsTempFile.cpp': No such file or directory

Following the error, I identify the compiler as follows:

In other words, the startup script correctly identifies the compiler, but a needed file appears to be missing (??)

Can anyone identify my error or issue?

Thanks
