Hi Jong Woo,
OK, I understand the problem.
You have an Eiger2 detector, which is not compatible with the master branch of ADEiger. The master branch works with the original Eiger detectors, not the Eiger2 which has some differences in the API.
There is a 1.8 branch at Diamond which is designed to work with the Eiger2.
https://github.com/dls-controls/ADEiger/tree/1.8
You are on the master branch, but you are 16 commits ahead of master. Where did you get those commits?
Ø
git diff R2-6 eigerDetector.cpp
You need to give that command after you cd to eigerApp/src.

Yes, it is Eiger2 4M from Dectris.
This is on the line 871 in eigerDetector.cpp.
mFWState->get(fwAcquire);
I think it is master branch.

Hi Jong Woo,
What model Eiger are you using? Is it from Dectris?
You said you were running R2-7 of ADEiger. This is not possible R2-7 has not been tagged yet. Are you running the current master branch, or R2-6?
Something is wrong, because your gdb traceback shows that eigerDetector.cpp line 871 is calling eigerParam::get.
In the master branch of eigerDetector.cpp line 871 is the first line below. In R2-6 line 871 is the second line below. Neither are calling eigerParam::get().
if(adStatus == ADStatusAcquire || (adStatus == ADStatusAborted && success))
setIntegerParam(ADStatus, ADStatusIdle);
Please verify what version of ADEiger you have. Are you running a git clone? If so please type
git status
git diff R2-6 eigerDetector.cpp
Mark
Thank you so much. I followed exactly what you said and I've got the followings
(gdb) backtrace
#0 EigerParam::get (this=0x0, value="") at ../eigerParam.cpp:410

For me on Centos 7 (very similar to RHEL 7) I get core.xxxxx files in the current working directory. I am not sure what I set up to get that, nothing that I remember.
However, you don’t need to get a core file at all, you can just run your IOC under gdb to start with.
Type the following:
gdb [path_to_ioc_application]
where [path_to_ioc_application] is the command you normally type to start the IOC, but without the second st.cmd argument.
Once you get the gdb prompt type
run st.cmd
Then when the IOC crashes you can type the command:
backtrace

Red hat enterprise linux 7.
What version of Linux are you running?

Thank you Mark, Michael and Guy. But I couldn't find any core dump files. There is folder /var/lib/systemd/coredump. But there is nothing in there. I also used the command 'coredumpctl'. I think something should appear if any.
$ coredumpctl list
No coredumps found.
The message keeps saying like below.
Segmentation fault (core dumped)
What's wrong?

To get a core dump out of systemd use the coredumpctl command.
See
man coredumpctl
or try
coredumpctl debug
