Hi mark

The error is because I was using camera IOC created on Base 3.15. However, when a fresh IOC is created on base 7.0.3, there is no such error. I am still digging out why IOC created on base 3.15 is giving "asyn" record syntax error on compiling on base 7.03?

Thanks
Sandeep

Hi Sandeep,

The error you are getting is one I have never seen before.

It seems like something is wrong on your end.  I know of a number of sites are running with 7.0.3.1 and ADCore R3-8 or master branch and are not seeing this problem.

What is your EPICS_HOST_ARCH?

I wonder if there is some problem with line endings on startup script or template files.  Can you run dos2linux on your startup script and any template files you have edited to try to remove any DOS line endings?

Mark

Hi Mark

You were right, I was on master branch in ADCore but then I checkout to R3-8 and error still remain same though the error line now in 656.
I also compiled with base 7.0.3, Asyn 4-38 & areadetector 3-8. The error again remains the same.

Thanks
Sandeep

If that is true then you are not using ADCore R3-8, which you said you were in your original message.

Here is the proof:

corvette:ADCore/ADApp/Db>git checkout R3-8 ADBase.template corvette:ADCore/ADApp/Db>cat -n ADBase.template
     1  #=================================================================#
     2  # Template file: ADBase.template
     3  # Database for area detector control using asyn driver and standard asyn device support
     4  # Mark Rivers
     5  # March 9, 2008
     6
...
   649  ###################################################################
   650  #  The asynRecord is used for mainly for trace mask               #
   651  ###################################################################
   652
   653  # Set ASYN_TRACEIO_HEX bit by default
   654  record(asyn,"$(P)$(R)AsynIO")
   655  {
   656      field(PORT, $(PORT))
   657      field(TIB2,"1")
   658      info("ADType", "ADDriver")
   659  }
   660

So in R3-8 line 660 is blank.

However, if I checkout the master branch of ADBase.template I see this:

   653  ###################################################################
   654  #  The asynRecord is used for mainly for trace mask               #
   655  ###################################################################
   656
   657  # Set ASYN_TRACEIO_HEX bit by default
   658  record(asyn,"$(P)$(R)AsynIO")
   659  {
   660      field(PORT, $(PORT))
   661      field(TIB2,"1")
   662      info("ADType", "ADDriver")
   663  }
   664

So I think you may be running the master branch of ADCore.

I am running the master branch and I don't see your error.

It will be interesting to see if the problem goes away if you run base 7.0.3.1.

Mark

Hi Mark

I used base 3.15 for areadetector 3-5 and asyn 4-33. Meanwhile I'll check with base 7.0.3

Also FYI, for me line no 660 points to field(PORT, $(PORT)) in ADBase.template file

Thanks

Hi Sandeep, > The error I get on loading ADBase template is - > dbLoadRecords("ADBase.template","P=Y-CAM:,R=cam1:,PORT=Y-CAM:CAM,ADDR=0,TIMEOUT=1") > Error: syntax error > at or before ":CAM" in path "/usr/local/epics/support/areaDetector/current/ADCore/db" file "ADBase.template" line 660 > dbReadCOM: Parser stack dirty w/o error. 1 > Also please note, there is no such error in Areadetector version R3-5 with asyn version 4-33. The reason for upgrade is to use ADVimba plugin instead of ADProsilica plugin. That is a strange error. Line 660 is a blank line at the end of ADBase.template. I am using asyn R4-38 and areaDetector R3-8 with no problems, and I think many others are as well. I notice that you are using base 7.0.2.2. I am using base 7.0.3.1. You said that you did not see the problem with areaDetector R3-5 and asyn R4-33. What version of base were you using with those versions of areaDetector and asyn? I would suggest updating base to 7.0.3.1 and see if the problem persists.
