Hi Randall,

I’ve got several IOCs built with EPICS7 and synApps 6.1.  They work with channel access but not with pvaccess (meaning caget works fine, pvget times out.

Is there something I need to do either in the IOC or in building EPICS/SynApps to enable PVaccess support in my IOCs?

Yes, this is from the example template Makefile:

# Link QSRV (pvAccess Server) if available
ifdef EPICS_QSRV_MAJOR_VERSION
    example_LIBS += qsrv
    example_LIBS += $(EPICS_BASE_PVA_CORE_LIBS)
    example_DBD += PVAServerRegister.dbd
    example_DBD += qsrv.dbd
endif

You don’t need the ifdef conditional though unless you might want to build the IOC against an EPICS build that doesn’t have the qsrv stuff built.

HTH,
