GLIBC 2.32 and 2.34 not found (required by ./beyla)

[dan1elm4rt1ns]

Hello! I'm attempting to set up Beyla on CentOS Stream 8 with kernel 4.18.0-519.el8.x86_64. According to the requirements, it should be supported in kernel versions 4.18 and above.

However, after installation, I encountered the following error:

sudo ./beyla
./beyla: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by ./beyla)
./beyla: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by ./beyla)

As shown in the image, I've already installed the specified packages from the documentation (kernel-devel, make, llvm, clang, glibc-devel.i686), but the issue persists.

While I understand I might avoid this error by running it on EL9, my aim is to make Beyla operational on EL8 unless that's truly not feasible.

Can anyone lend me a hand here?

Thanks in advance for any assistance!

Hi @dan1elm4rt1ns, unfortunately even if this worked with the older glibc, we'll hit an issue with the kernel. At some point in time, to get better efficiency from capturing events at the kernel level, we switched to using ring buffers instead of perf buffers, which require kernel 5.8 for eBPF.

We've been discussing adding support for older kernels, maybe we can turn this into a feature request and we'll put it on our roadmap?

Thanks a bunch for the feedback!

From what I gather, does that mean it's not really worth my time to keep trying to tackle this issue and figure out a way to update GLIBC on EL8? Would it be wiser to just hold off and test exclusively in EL9 environments for now, you reckon?

[grcevski]

Yeah, I think sticking to EL9 for now is the only option, until we add support for older kernels. It's not much of a stretch that we'll do it, we just need enough feedback that this matters, so that we prioritize it.

Alright, thank you very much for the prompt response! I'll maintain the labs at EL9 for the time being. Great job!
