Thanks, Janet

You were absolutely right, it worked.
Just for people who will make static build on NT: despite the fact that when
you build default
EPICS base, xxxObj.lib libraries were created, you can not use them in the
static application
build. You have to build base EPICS with both STATIC_BUILD=YES and
SHARED_LIBRARIES=NO
swithes. You can see the difference immediately, even size of the libraries
is different, for example
casObj.lib is 1,355Kb in the default (DLL) build and 300Kb only in the
static build.
It's still unclear to me why in the default DLL base build those libraries
xxxObj.lib were created ..
to work with DLL's xxx.lib and created xxx.dll's are enough.

Vladimir
