Subject: SENS from WRS and PowerPC; working

   Hi,

there has been an e-mail about the new "SENS" IP kernel from Wind
River Systems on tech-talk dated December 7, 1998 by J. Hill. In there
he recommended to not specify the "SENS" option when building Tornado.
This has the drawback that WindView is not available.

 The problem is that there is a name clash for the PowerPC
architecture. WRS defines in one of their header files (net/mbuf.h) a
macro m_type which clashes with a variable of the same name in a
structure used by Channel Access. I changed the name of the variable
m_type in the code of CA (10 files had to be changed) and now CA seems
to work with the SENS IP kernel!

 The files that were changed are given below. The path is relative to
EPICS_BASE/src/

ca/access.c
ca/caProto.h
ca/service.c
cas/generic/casClient.cc
cas/generic/casClientMon.cc
cas/generic/casCtxIL.h
cas/generic/casDGClient.cc
cas/generic/casStrmClient.cc
cas/generic/outBuf.cc
rsrv/camessage.c

 I tested the new EPICS with the new kernel on a couple of IOC
applications and discovered, so far, no new problems using EPICS
3.13.0.beta12, Linux as host and mv2306 as target. A test on solaris
and mv167 will be done next week, but I don't expect any
problems. Could the above mentioned changes included later into the
EPICS distribution? Jeff?

 Cheers, Markus
