Hi Andre,

I have never seen that error before.

It does appear that "asyn.dbd" is being included multiple times, but that has never been a problem before that I know of.

testInclude.dbd is the following:
#######################
include "base.dbd"
include "asyn.dbd"
include "devTestBlock.dbd"
include "drvAsynSerialPort.dbd"
include "drvAsynIPPort.dbd"
registrar("asynExampleRegister")
registrar("echoDriverRegister")
registrar("addrChangeDriverRegister")
registrar("interposeInterfaceRegister")
#######################

asyn.dbd is the following:
#######################
registrar(asynRegister)
registrar(asynInterposeFlushRegister)
registrar(asynInterposeEosRegister)

#
# The following ties this to EPICS records.
# Applications which wish to use ASYN without EPICS
# records can comment out the following lines.
include "asynRecord.dbd"

include "devEpics.dbd"

driver(drvAsyn)
#######################

drvAsynSerialPort.dbd is the following:
#######################
registrar(drvAsynSerialPortRegisterCommands)
include "asyn.dbd"
#######################

So asyn.dbd is being included both directly in testInclude.dbd, and indirectly through drvAsynSerialPort.dbd.  asyn.dbd is doing "registrar(asynRegister)", which is the duplicate name error you are getting.

I don't know what code is generating the "Duplicate name 'asynRegister'" error message?  Is it perl?

Mark

Subject: Error building asyn4-20 on CentOS 6.3

Greetings,
I have been trying to build the following asyn driver on my CentOS 6.3
(64bit) linux system but with no luck:

	http://www.aps.anl.gov/epics/download/modules/asyn4-20.tar.gz

First I found out a patch that needed to be applied to the code:

	http://www.aps.anl.gov/epics/tech-talk/2012/msg01794.php

Then the make went a bit further but then it ends with the following error:

(I'm an EPICS newbie, so I'm probably missing something pretty obvious.)

I've attached the full make output.

Anyone else experienced a similar error before?

Thanks,
