Re: Regading Conflicting libraries for CA Lab & labCA

[Till Straumann <strauman@slac.stanford.edu>]

I think what you ultimately want is to avoid is having
labCA and calab/labview (or other epics CA clients)
using different versions of the epics base libraries
(ca.dll, Com.dll).

-> make sure all your epics clients are built against
    the same epics base version
-> have PATH point to the DLLs of this base version

this way you ensure all clients work correctly.

If you must use different versions of base for labCA
and calab then you must make sure the PATH points
to (and only to) the correct version when you use either
labCA or calab. Having multiple versions of ca.dll/Com.dll
in your PATH can potentially cause trouble.
