Build error: ‘class epics::pvAccess::ChannelProvider’ has no member named ‘flush’

[djvine]

EPICS7 noob trying to build masar. I have base 7.0.2 installed ok, synapps (latest tagged version of each) build ok against epics7.

When I try to compile masar i get the error below. I have the following in my release file:
EV4_BASE=/opt/epics7/base
PVACLIENT=$(EV4_BASE)/pvaClient
PVDATABASE=$(EV4_BASE)/pvDatabase
PVASRV=$(EV4_BASE)/pva2pva
PVACCESS=$(EV4_BASE)/pvAccess
NORMATIVETYPES=$(EV4_BASE)/normativeTypes
PVDATA=$(EV4_BASE)/pvData
PVCOMMON=$(EV4_BASE)/libcom

EPICS_BASE=/opt/epics7/base

Your RELEASE settings look like they are made for compiling against EPICS 3 + EPICS 4 (i.e. the PVA modules separately).

For use with EPICS 7 (that has the PVA modules merged) the settings have to be different. I would say (never having compiled MASAR) that all these variables should point to the same location, your installed EPICS 7.

This reminds me of #21 which hasn't been merged. It will certainly avoid this error as it removes all of the compiled code.

I can't remember atm. if there was a reason why #21 isn't merged. Might just be laziness on my part. As it appears that the current code doesn't build, and the CI tests for #21 pass, I'm going to go ahead and merge.
