libbasicfuncs.so error

Hello! Using syslog-ng 4.6.0-bp156.1.4 on SUSE Linux Enterprise Server 15SP6 on s390x, via the packageHub repository. I see this error frequently in the logs and when I run # syslog-ng -s... /usr/lib64/syslog-ng/libbasicfuncs.so: error: symbol lookup error: undefined symbol: fmod (fatal) I also have several identical systems with the same version of syslog-ng that do not return this error. Can you tell me if there is an actual problem with this, or is the message moreso cosmetic? Thanks, Rob

Fedora 44, CentOS 7 and Amazon Linux syslog-ng questions
by Peter Czanik (pczanik) 19 May '26

Hi, This is a repost of my blog from last week, here on the mailing list. I need your feedback on CentOS 7 and Amazon Linux 2023 packages. You can respond here, or even better: at the URL at the end of my e-mail. Peter Fedora 44 was announced last week: syslog-ng 4.11 is part of it. While checking the Fedora Copr build service for Fedora 44, I realized that CentOS 7 and Amazon Linux 2023 packages are also there. I have a few questions about those for you! Fedora 44 The availability of the Fedora 44 release was announced last week. Vesion 4.11 of syslog-ng, the current latest release, is part of it. As usual, I did a quick test: everything works as expected. RHEL 6 The removal of RHEL 6 packages from Copr was announced many years ago. Then, the countdown was silently canceled. I have just checked: RHEL 6 packages are no longer available, so I deleted all my related repositories. Also, I deleted a couple of temporary test repos along the way. CentOS 7 When talking to product manager friends around the world, I realized that syslog-ng is not an “enterprise” application. “Enterprise” developers are still actively maintaining packages for RHEL 6, when even RHEL 7 has reached end of life a long time ago. Of course, this is just a satirical definition of “enterprise”, at least in my view… Support for RHEL 7 / CentOS 7 was dropped in syslog-ng a month before the distro became end-of-life. Copr announced the deletion of CentOS 7 packages, but after a while, the countdown suddenly disappeared. Packages built 10+ years ago are still here, and CentOS 7 is still a valid build target. Question: is there anyone still using my syslog-ng packages on RHEL 7 / CentOS 7? Otherwise, I would be happy to delete anything related from my Copr repositories. I could delete many repositories, save storage, and I would not have to deselect them as a build target during package builds. Amazon Linux 2023 Another question mark in my mind is Amazon Linux 2023 support. If we can believe the download statistics provided by Copr, then this is one of the most popular syslog-ng repos on Copr. However, over the years, I only received a single feedback about it, which was on Twitter years ago: “Thanks, I use it.” That is all. While there were regular requests to create these packages, nobody asked for features, updates, whatever. The repo is still stuck at syslog-ng version 4.8. Question: should I update syslog-ng to a more recent version, as time permits? What is next? Share your thoughts with us in this syslog-ng GitHub discussion: https://github.com/syslog-ng/syslog-ng/discussions/5691 or reach out to me on Twitter / Mastodon / LinkedIn.

The syslog-ng Insider 2026-05: OTEL; central log collection; old Mac

Dear syslog-ng users, This is the 140th issue of syslog-ng Insider, a monthly newsletter that brings you syslog-ng-related news. NEWS Streaming syslog-ng data to your lakehouse using OTEL Version 4.11.0 of syslog-ng contains contributions from Databricks related to OAuth2 authentication. Recently, they published a blog about how this enables their customers to send logs to their data lake using syslog-ng and the OpenTelemetry protocol. https://www.syslog-ng.com/community/b/blog/posts/streaming-syslog-ng-data-t… Central log collection - more than just compliance I often hear, even at security conferences that “no central log collection here” or “we have something due to compliance”. Central logging is more than just compliance. It makes logs easier to use, available and secure, thus making your life easier in operations, security, development, but also in marketing, sales, and so on. https://www.syslog-ng.com/community/b/blog/posts/central-log-collection---m… Compiling syslog-ng on an old Mac I have an aging, but fully functional MacBook. I bought it for syslog-ng testing, but I also use for watching movies. Homebrew no more fully supports old, Intel-based Macs. This blog helps to compile the latest syslog-ng release on these old, but otherwise functional machines. https://www.syslog-ng.com/community/b/blog/posts/compiling-syslog-ng-on-an-… WEBINARS * You can learn about upcoming webinars and browse recordings of past webinars at https://www.syslog-ng.com/events/ Your feedback and news, or tips about the next issue are welcome.
