People are keeping me asking for a Windows installer. Is this now properly working, also under Windows 11? If you send me the executable, I could upload it to the distribution.

Do people have to install cygwin before they can use it, or will the executable runn just by itself? If I understand correctly, the MinGW package would not require a runtime library, right?

Best,
Stefan

Hi Stefan,

Some updates for Windows version.

I spent last WE to try to build ELOG on Windows from MSVCODE, MSCV, crosschain tool under linux etc, but in vain.

ELOG MSVC projects file are obsolete for last MS C++, and after migration, so much error or missing libs for SSL/Ldap/krb5 which should be built... I drop the sponge :-P

With mingw64 under Linux (docker/Debian), the code has also to be updated (C++11), but I don't get a build after all (also libs missing and must be built).

Finally, I can build Windows version from Windows with CygWin gcc-c++ as I did in the past. All the dependencies are available from CygWin installer. I got problems with strlcpy file missing, need to drop inlcude from elog.c and elogd.h as mxml doesn't include it anymore...

I find a Win64 CI/CD solution on AppVeyor which is free for OSS project. After creating account and add link to my ELOG test Bitbucket repo, ad new files (appveyor.yml, buildming script, update NSIS script for CygWin DDL, add tool for service), it builds automatically an elog-ver-release.exe artifact : (current build from GIT with SSL/LDAP/KRB5 available on month up to March 3, 2024 : https://ci.appveyor.com/api/buildjobs/logp7r8f0kcjq9pp/artifacts/elog-3.1.5-a720145.exe)

I installed this NSIS bundle on my PC and it's starting fine as a service.

I will send you the files/patchs if AppVeyor could be used for Windows CI/CD in your project.

Bye,

Laurent

NB: the AppVeyor build log enclosed, need some cleanup...

For Windows target, It's supported in Bitbucket but only with private agent :-(

So I tried to build using docker hub MSVC image (abrarov/msvc-2019) but pipeline fails to retrieve the image. Maybe I need to swipe on alternative images, or these images with MS software are unaccepted from Atlassian...

Also, I tried to crosscompiling ELOG Win32 from Linux with g++-mingw-w64-x86-64, but Makefile/sources need to be patched to manage this 'platform'... For the moment, it fails. :-(

Next solution : use Wine in Debian image to build Elog with mingwin as I know that it works (under Windows :-)). Will be tested after all...

For Windows it's more than just getting the .exe. Users want an installer. I used the Nullsoft Scriptable Installer (NSI), but I have no clue if this still works today. But there is still the elog.nsi script in the repository. Next, users want elogd as a service running in the background as a "service". I'm pretty sure the old way of doing that has changed and one would at least have to test this. Unfortunatley I switched to MacOSX about ten years ago (actually most of ELOG has been developed under Windows, but these days are gone), so I'm kind of illiterate in the Windows world now and don't have any time to change that.

Thanks to your stack trace, I found a case where a string might get overwritten, but only if the attachment file name is longer than 256 chars. I fixed the code and made a new RPM:

  https://www.dropbox.com/scl/fi/r37qx9aka5ytt3j7vn4km/elog-3.1.5-20241213.el8.x86_64.rpm?rlkey=knct99pdltggunrbmyr2hpfe5&st=pkre24aq&dl=0

Alternatively, you can compile from sources. Give it a try.

Apparently Codecogs have changed their URL. I tried the update from 

  https://editor.codecogs.com/depr/CK_Editor_v4x.php

but it did not help. The CK Editor v5 is quite different from v4 (like they require node.js to install it), so putting it into elog would be some major work.

is there any update on this bug? Has anyone else observed the same problem?

Hi!

I am not sure if this is a know issue: it seems that the equation editor does not work anymore. Is there any fix or alternative method to type latex formula in the log? 

Thank you!

I stopped making tar files, since most people building elog from sources just pull it from the bitbucket repository:

$ git clone https://bitbucket.org/ritt/elog --recursive
$ cd elog
$ mkdir build; cd build;
$ cmake ..; make

So this never made it into the download area ?  elog-latest.tar is elog-3.1.5-1 and contains no files from 2024 or 2025 .

Thanks

Thanks Stefen!

I built from source (ELOG V3.1.5-3a5f2f00) and I confirmed as fixed.

Probably some very strange URL form nexpose to trigger a potential buffer overflow. If I get the precise URL which crashes elogd, I can reproduce and fix it.

Otherwise my usual advice: Run elogd behind an Apache proxy and do the authentication there. This way nexpose does not get to elogd, it will stop at the Apache (without the proper credentials).

We have since discovered that the security team is scanning the box in question once a week when the service crashes, with nexpose.

So if you see something similar then you might want to explore that.
