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

My MacOS (10.12.2) elogd version V3.1.2 is a recent git commit (edc5e85), due to the fix to my earlier-described issue solved in the thread here: https://midas.psi.ch/elogs/Forum/68519.

I am trying to (re-)set up Mirror functionality with a linux server running the standard public (V3.1.2-bd75964).  I had initially updated
the linux server so that it also had the latest git commit (edc5e85), but could then not even add new logbook entries that involved attachments to it.

The attached screenshot shows the behaviour after doing a synchronization (with Mirror simulate = 1) following first having ensured that the local (Mac)
and remote (linux) ELOGs initially showed "All entries identical" when doing a simulated synchronization, and then having edited local entries
9707 and 9709 by uploading (different) attachments to them.

When I switch from SSL = 1 to SSL = 0 and I use http:// instead of https://, the ability to upload attachments to logbook entries returns.  With
both Chrome and Safari browsers, with SSL = 1 the file upload hangs after only a small percentage of the file has been uploaded.  I ran the following
openssl diagnostic on my elogd port.  Would anyone have advice on what might be causing such errors?

For the time being, I am deeming ELOG 3.1.2 unusable with https (SSL = 1) functionality on my "Debian GNU/Linux 7 (wheezy)" server
with "OpenSSL 1.0.1t", due to the described apparent issues with SSL.  Reverting to http (SSL = 0) brings back my ability to upload attachments
and synchronize with a remote elogd running on a MacOS laptop.

Further to my comment in https://midas.psi.ch/elogs/Forum/68549, if the described synchronization requires attachment(s) to be transferred from
my Mac laptop to the Debian linux server (with SSL = 0 set), it fails in all the tests that I tried.

To check whether these problems are linked to the OpenSSL version on the linux server, we also tried building an elogd executable using 1.0.2j

Hi Erkcan,

I observed similar behaviours when attempting to do SSL uploads and mirroring over a WAN (see some of my recent posts).  Having not received
any responses/help, and no time to try debugging the source myself, I've changed the way I use ELOG such that my attachment uploads are always local
