RE: libraries required by CA client application

["Russ Berg" <Russ.Berg@lightsource.ca>]

Hi all, I use cppBuilder (win2k) a fair bit for operator screens, to
link in the ca stuff all I did was compile the win32-x86 EPICS base
using MSV6, then create borland compatible 'lib' files of com.dll and
ca.dll by using 'impdef' and 'implib' (both come with builder). Add the
resulting ca.lib and com.lib to your project and include 'cadef.h' in
your source and you are ready to make ca calls. I have tested a little
with Kylix and was able to make it work with the gnu compiled libraries.

Hello Sun Xiaoying,

Your Linux application that uses the CA client library to
put/get/monitor will need to link with libca and libCom. These libraries
are located in <EPICS base>/lib/linux-x86. The Borland specific options
that will be required by kylix (C++ builder) will be different than the
options used by the EPICS make files which are GNU based by default on
Linux. If you run a Borland based EPICS build on windows and watch the
compile/link lines this may be helpful when choosing the build options
for your kylix C++ Builder environment on Linux (I don't know that this
will help, but it might be a place to start).

PS: You have identified an omission (a vast gaping hole perhaps) in the
channel access documentation. I have attached an updated CA reference
manual which has a small addition which starts to address the problem.

PPS: Note that there are some significant bugs in the EPICS R3.14.5 CA
client library which have been fixed in R3.14.6.
