Category: Question  OS: Mac OSX  ELOG Version: 3.1.2 
Subject: Re: elogd crashes during Find and Mirror operations under MacOS 
I have no experience with ELOG on OSX, therefore I can only give very vague and indirect support (sorry).
I suggest that you first try an installation without actual logbook data (just move it to a save place for a while). Does a "find" still crash elogd?
If elogd is still crashing, you should prune your configuration until it stops crashing. Submit the smallest config here that still crashes the logbook.
Since the logbook starts crashing after a sync, I would rather guess that it is somehow related to specific logbook entries. It would be helpful if you could isolate the offending entries.

Another approach would be to compile elogd with "make debug" and run it in the debugger. Once it crashes the debugger will show where it happened.

Happy New Year! Andreas

When installing ELOG 3.1.2 on my Mac Sierra (10.12.2) with the latest XCode 8.2.1, it seemed to install fine but for one warning when building elogd:

  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.

My installation was done with "sudo make install", as the instructions state.  I have also been using the prescribed "launchctl" approach.

1. Is the above warning something that needs attention/correcting?

2. My elogd crashes now every time that I attempt any kind of "Find" operation.

3. I synchronize my MacOS version of elog with a linux-based version on my university's web server.  I have installed 3.1.2 on the linux server, and it is running there without problems.  When I now try to synchronize my 3.1.2 ELOG on MacOS laptop with the same version on my linux server, it appears to do the first mirroring operation correctly, but elogd crashes when I try a second synchronization at a later time.  (For now, I have "Mirror simulate = 1" to prevent inadvertent damage.)

Can anyone help me with the above points?

Thank you,

Andreas
