Re: elogd crashes during Find and Mirror operations under MacOS

Thank you very much (both Andreas and Stefan)! The build now runs without warnings, and I am now able to do Find operations without crashes. I still am having some issues with the synchronization, but I suspect that this is elog-content related, so will in the coming days do some more testing from CERN (where I have higher bandwidth with my home institution in Canada). Incidentally, I had to add a line to Makefile in order to be able to build on my Mac. See below, in case you want to update the Mac Makefile for others.

Many thanks again,

Andreas

ifdef USE_SSL

ifneq ($(USE_SSL),0)

CFLAGS += -DHAVE_SSL

CFLAGS += -I /opt/local/include

LIBS += -lssl

endif

(You may wish to update the distribution if you think it may benefit other Mac users.)

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

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

Gmail email smtp settings

V3.1.1-3f311c5

Hi all

I am trying to send email via Gmail smtp with no success. Elog uses port 25 which is not allowed. I need to use 587 or 465 ports to send mail. How can I change the port?

Have a good year all!

Re: Elog source code giving errors when compiling about missing header files

You need the netdb.h header file to compile elog. I see that you compile under Windows. You have to make sure that your compiler installation comes with all header files. The netdb.h file is usually in /usr/include under Unix.

I downloaded the source code from the git repository which contained the new fix that was made for the missing username-crash error. I tried compiling the elogd.c file using a GCC compiler and it gave an error about missing header files. It first gave an error about netdb.h file and when I commented that header file call, it gave further errors for other header files. I do not really understand why it gives an error about that.
