Hi everyone,
We hit a bug in stunnel-5.05 and it continues in 5.06. The problem comes from systemd which moved sd_listen_fds() form libsystemd-daemon.so to libsystemd.so. However, stunnel's configure.ac still has
AC_SEARCH_LIBS([sd_listen_fds], [systemd-daemon])
For backwards compatibility, this should probably be
AC_SEARCH_LIBS([sd_listen_fds], [systemd], [], [ AC_SEARCH_LIBS([sd_listen_fds], [systemd-daemon]) ])
or similar. Please refer to our downstream bug:
https://bugs.gentoo.org/show_bug.cgi?id=525234'
Thanks.
