Done.  Mark, you were right in that I was did not have an CAS up and running while I was attempting to invoke caExample.   All is working now. 

 

Thanks for the help/assistance. 

 

 

Regards,

 

Florencio

To get rid of the carepeater error messages just put the path to epics-base/bin/cygwin-x86 in your PATH environment variable.

 

The timeout error is another problem.  Are you running an IOC that contains the PV ai1?

Hi All,

 

I am new to EPICS and trying run thru the example applications.   Specifically, I am encountering the following error  when attemping to Channel Access Host Example per the procedures in Section 2.3 of the EPICS Application Developer’s Guide.

I’ve successfully built EPICS base (3.14.12.1) via EPICS_HOST_ARCH = cgwin-x86.    The steps do not mention anything about a caRepeater.   Looks like I’m missing something really subtle (as an EPICS “new-bie”).  Any help/assistance/info will be greatly appreciated. 

 

 

Thanks in advance,

 

Florencio Cid
