Re: EPICS V4

[Ralph Lange <Ralph.Lange@gmx.de>]

Summary of the off-list answers for tech-talk members and archives:

If you want to use pvaSrv you *must* build V4 with Base 3.14.12.x (preferably 3.14.12.4 or later). The changes that were made in Base 3.15.1 include API changes which have not been implemented in pvaSrv yet. If you're not going to build the current version of pvaSrv though, you can use Base 3.15.1.

As Base 3.15.1 has just been released and is not used in production yet, the primary goal was to support all existing EPICS users, who are using 3.14.

The next release of V4 will fully support building all components against both EPICS Base 3.15 and 3.14.12.

This compatibility will be maintained for some time, to allow existing facilities running pvaSrv on their 3.14.12 IOCs.
However, certain future features of pvaSrv (e.g. grouping multiple PVs on one IOC into a single PV Access structure) will only be available when compiled against Base 3.15 or 3.16, if they depend on mechanisms that are available only in those versions of Base. Eventually we will have to stop supporting 3.14, but certainly not before 3.15 is well established and low risk to update to.
