Hi Ralph,

Interesting question that just came up:
Is it possible (maybe with the cmake approach that I remember Martin and/or Michael using) to build the pvData/pvAccess C++ libraries completely separate, i.e. without linking to or having EPICS Base around?

You will need libCom — pvData includes many headers such as epicsMutex.h, epicsTime.h, epicsString.h etc., but that ought to be sufficient for the core PVA modules. The test coverage for libCom is probaby better than any other part, although it may be quite a way from what you need. You should be able to get by with a subset of the libCom sources though.

I suspect more of a problem for your requirements would be test coverage for the pvData and pvAccess code itself. Could you contribute funding to writing tests for pvxs instead? I guess that depends on your timing. That is also using headers from libCom, so you would need that in either case.

HTH,

Background:
ITER's Real-Time Framework (RTF) that will be running the plasma control system is classified as software integrity level 1 (SWIL-1), requiring it among other stuff to adhere to the HIC++ standard and provide pretty good test coverage (>95%).
Now the RTF wants to use PVAccess as transport layer for configuration, slow control and monitoring. This would obviously pull the PVA source code into the SWIL-1 scope. Will we be able to keep the rest of EPICS Base out of this?

Thanks for any insights.
~Ralph
