[syslog-ng] error while loading shared libraries: libsyslog-ng-3.23.so.0

Hi, I compiled syslog-ng 3.23 on Debian 10 (./configure --enable-systemd --with-systemdsystemunitdir=/etc/systemd/system --enable-mixed-linking) When I try a simple "syslog-ng -F", I get the following error: "syslog-ng: error while loading shared libraries: libsyslog-ng-3.23.so.0: cannot open shared object file: No such file or directory" However.... ldconfig -v | fgrep syslog libsyslog-ng-3.23.so.0 -> libsyslog-ng.so And .... # find / -name "libsyslog-ng-3.23.so.0" -print /usr/local/lib/libsyslog-ng-3.23.so.0 Any ideas ??
