Hi,

It's possible to build elogd under windows with cygwin, but not sure that is the best as it requires a lot of dependencies that should be included to dist package to be runnable everywhere.

After

• installation of dependencies (gcc-g++, make, libssl1.1, libssl-devel, opendlap-devel, libopenldap2, libkrb5-devel, libkrb5_3) using CygWin setup program,
• instalkation of git tool and clone the git repo (git clone https://bitbucket.org/ritt/elog --recursive),
• modification of Makefile to build with Kerberos/ldap/ssl support,

from cygwin bash under Windows 11, you can build elog :

With that, elogd starts and the site is usable.

NB: after installing imageMagick, elogd starts with activation of image manipulation features.

For who as interested, I enclosed 2 zips, with (elog-win64_wDLL.zip) or without (elog-win64.zip) Cygwin DLL (licence: https://cygwin.com/COPYING). The build uses the current git version.
