rsyslog addon omrelp.so not loaded due to undefined symbol

jsaathof · September 13, 2023 at 4:25 PM

I am trying to get the rsyslog working. I have found out the the settings had to be done from the master profile. Now that I have correct settings and a config the service still does not start. This is due to a missing symbol error. The symbol BIO_get_callback_arg comes from crypt/bio/bio_cb.c according to this page: https://linux.die.net/man/3/bio_get_callback_arg

I am running Libreelec 11.0.3 on x86_64 (Intel NUC7i3BNK)

This is the error when starting rsyslog by hand:

please use

systemctl status service.rsyslog

to test, as it sets up the environment and configs.

This is specifically for the rsyslog RELP module. I am using the same command and environment as the service does. The config is present and correct. And 'systemctl status' does not show enough. If I configure the RELP protocol IT DOES NOT WORK.

If you read the output I sent carefully you'll see that the error in the config file is because the RELP module cannot be loaded. As it says: "inputs would run but no output whatsoever were created". And this is due to the missing symbols in the module. The rsyslog package, or rather the omrelp.so module is built against other libraries than present on the system.
