Hi Xiaoqiang,

Thanks for the info.

Does this mean that I would need to build pcaspy from source to get it to use EPICS 7?

And that the binary version of pcaspy that I installed previously is using the version of EPICS I was using (what EPICS_BASE pointed to) when I installed it?

Thank you,

Ray

Hi Ray,

Here is the steps I use to build PCAS module together with EPICS base.
