RE: quadEM-R7-0 ParamValNotDefined

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Hi Rong,

 

You appear to be running asyn R4-36.

 

You are getting this error:

 

NDStatsConfigure("STATS1", 20, 0, "TetrAMM", 0, 0, 0) terminate called after throwing an instance of 'ParamValNotDefined'

  what():  paramVal::getInteger value not defined Aborted (core dumped)

 

I do not understand that.  The only place where paramVal::getInteger should be called is in this line in asynPortDriver R4-36:

https://github.com/epics-modules/asyn/blob/89c2b93d14cdb7fe48d490785cd7780c1b997277/asyn/asynPortDriver/asynPortDriver.cpp#L288

 

Note that paramVal::getInteger is called in a try/catch block, and exception ParamValNotDefined is explicitly caught.  So it should simply return asynParamUndefined to the function that called paramList::GetInteger, which is normally asynPortDriver::getIntegerParam().

 

Your error message says that the crash generated a core dump.  I think you need to run gdb on that core file and send the output of the gdb “backtrace” command.

 

Alternatively you can run the IOC again under gdb as follows:

 

gdb ../../bin/linux-arm/quadEMTestApp

run st.cmd

 

(when it crashes type this command)

backtrace

 

That will show the call stack when it crashed, and we may be able to figure out why it is happening.

 

Mark

Subject: quadEM-R7-0 ParamValNotDefined

 

Hello,

 

Sorry I am living in the past. I am trying to install the old version

quadEM-R7-0 to match the  EPICS_base version (3.14.12.8) and Asyn version in use.

 

I installed everything without vxWorks, with the intention to run the IOC on a PC. Currently working on RHEL linux-arm inside VMware Fusion.

 

The TetrAMM instrument is new, but I guess the error message is not about hardware but EPICS software. The printout of starting IOC is as

follows:

 

[rh@localhost iocTetrAMM]$ ../../bin/linux-arm/quadEMTestApp st.cmd

errlogInit(5000)
