Experimental Physics and
Industrial Control System

Dear Tech-Talk,

 

I am trying to set up a usual EPICS build with support modules on my Windows 10 64bit machine. I am using MSYS2 as an environment. All other modules were installed without any problem (asyn, calc, …).

The error that appears is below. Has somebody encountered it before?

 

Best regards,

Johannes
