Hi Yong,

More recent versions of base have become more strict about including the same dbd file more than once.  That is what is causing your error.

This is the command with the error:

perl -CSD /home/yhu/src/base-3.15.6/bin/linux-x86_64/dbdExpand.pl   -I. -I.. -I../O.Common -I../../../dbd -I/home/yhu/src/asyn/dbd -I/home/yhu/src/StreamDevice/dbd -I/home/yhu/src/base-3.15.6/dbd -o hp3458a.dbd base.dbd xxxSupport.dbd dbSubExample.dbd hp3458aHello.dbd initTrace.dbd devHP3458A.dbd system.dbd asyn.dbd stream.dbd drvVxi11.dbd

asyn.dbd includes asynRecord.dbd, and that is correct.

The problem must be that one of your previous dbd files also includes asyn.dbd or asynRecord.dbd.   I would suggest first looking in these files and deleting the lines that include asyn.dbd or asynRecord.dbd.

xxxSupport.dbd
hp3458aHello.dbd
devHP3458A.dbd
system.dbd

Mark

Subject: dbdExpand.pl: Duplicate definition of record type 'asyn'

Hi Mark,

As you know, I have trouble with hp3458a which is using very old asyn & StreamDevice. So I am trying to rebuild the hp3458a IOC.

I git clone the latest asyn from GitHub (commit 07f52d99f1977b76191dda505cf9d24b90548743). Firstly I tried to compile it on Debian-7 (wheezy) against base-3.14.12.3 which is pre-installed on our Debian-7 servers. However, it failed: ../../asyn/drvAsynSerial/drvAsynIPPort.c:467:21: error: 'O_REUSEPORT' undeclared (first use in this function).

A little google search indicates this might be related to Debian 7's old kernel or system library. So, I moved to a newer server with Debian-9 (stretch) and built the latest asyn and the latest StreamDevice successfully against base-3.15.6 which is pre-installed on our Debian-9 servers.

When I try to rebuild the hp3458a IOC against the latest asyn & StreamDevice, it fails:

Creating dbd file hp3458a.dbd

Context: recordtype(asyn) in file '/home/yhu/src/asyn/dbd/asynRecord.dbd' in file '/home/yhu/src/asyn/dbd/asyn.dbd'

  while reading 'asyn.dbd' to create 'hp3458a.dbd'

dbdExpand.pl: Exiting due to errors

What is the best way to fix this problem?

Thanks,

Yong
