Hi -- I'm attempting to build a docker container of Kea 1.4.0 and hitting an issue around logging initialization when attempting to load hook libraries.
The relevant bits of the Dockerfile: ``` FROM ubuntu:18.04 RUN apt-get update && apt-get install -y --no-install-recommends libtool autoconf g++ libssl-dev liblog4cplus-dev libboost-system-dev WORKDIR /build/ RUN wget https://www.isc.org/downloads/file/kea-1-4-0-p1/?version=tar-gz -O kea.tar.gz \ && mkdir kea && tar -C kea --strip-components=1 -xzf kea.tar.gz \ && cd kea && ./configure --enable-shell --enable-static-link \ && make -j $(getconf _NPROCESSORS_ONLN) -l $(getconf _NPROCESSORS_ONLN) && make install \ && cd /build/ \ && rm -r kea* && ldconfig ``` When I run `kea-dhcp4` with the following config: ``` { "Dhcp4": { "hooks-libraries": [{ "library": "/usr/local/lib/hooks/libdhcp_lease_cmds.so" }], "control-socket": { "socket-type": "unix", "socket-name": "/tmp/kea-dhcp4-ctrl.sock" }, "lease-database": { ... }, "expired-leases-processing": { ... }, ... }, "Logging": { "loggers": [ { "name": "kea-dhcp4", "output_options": [ { "output": "stdout" } ], "severity": "INFO", "debuglevel": 0 } ] } } ``` I get an error as follows: ``` 2019-01-22 20:44:22.375 ERROR [kea-dhcp4.hooks/142] HOOKS_LOAD_FRAMEWORK_EXCEPTION 'load' function in hook library /usr/local/lib/hooks/libdhcp_lease_cmds.so threw an exception: reason attempt to access logging function before logging has been initialized 2019-01-22 20:44:22.375 ERROR [kea-dhcp4.hooks/142] HOOKS_UNLOAD_FRAMEWORK_EXCEPTION 'unload' function in hook library /usr/local/lib/hooks/libdhcp_lease_cmds.so threw an exception, reason attempt to access logging function before logging has been initialized 2019-01-22 20:44:22.375 ERROR [kea-dhcp4.dhcp4/142] DHCP4_PARSER_COMMIT_FAIL parser failed to commit changes: One or more hook libraries failed to load 2019-01-22 20:44:22.376 ERROR [kea-dhcp4.dhcp4/142] DHCP4_CONFIG_LOAD_FAIL configuration error using file: /usr/local/etc/kea/kea-dhcp4.conf, reason: One or more hook libraries failed to load 2019-01-22 20:44:22.376 ERROR [kea-dhcp4.dhcp4/142] DHCP4_INIT_FAIL failed to initialize Kea server: configuration error using file '/usr/local/etc/kea/kea-dhcp4.conf': One or more hook libraries failed to load ``` My instinct is that this is an issue with the linking but `ldconfig -p` looks as I would expect. Any advice or help would be appreciated. Thanks, Joe
