Subject: pvAccessCPP: destroyable.h

This defines  method destroy.
Most or all uses of destroy have been deprecated.
But warnings like the following appear
../pv/channelProviderLocal.h:84:46: warning: ‘virtual void epics::pvDatabase::ChannelProviderLocal::destroy()’ is deprecated [-Wdeprecated-declarations]
     virtual void destroy() EPICS_DEPRECATED {};

But if the destroy method does not appear then the code will not compile.


If the following change is made to destroyable.h then the code will compile.

mrk> git diff src/utils/pv/destroyable.h
diff --git a/src/utils/pv/destroyable.h b/src/utils/pv/destroyable.h
index f9afc47..2c38eea 100644

Michael,

Can this change be made?


Marty
