beyla 0.3.2 can't run in centos7

beyla 0.3.2 can‘t run in centos 7： report： ./beyla: /lib64/libc.so.6: versionGLIBC_2.32' not found (required by ./beyla) ./beyla: /lib64/libc.so.6: version GLIBC_2.34' not found (required by ./beyla) system version： CentOS Linux release 7.9.2009 (Core)

Hi @kazu12, thanks for the report! is this a bug that appeared in Beyla 0.3.2? In other words: did Beyla 0.3.1 worked well?

[mariomac]

Self-response: Centos 7 uses Linux Kernel 3.10 and Beyla requires eBPF features that are available from Kernel 5.4. We can't fix Centos 7.

I've tried all the current versions and I'm getting this bug. I speculate that the reason is that the binary version of the compilation environment is based on a more advanced Linux distribution.

[mariomac]

I'm sorry to not be able to solve your issue. Independently of the version of the Go compiler and the libraries it uses, CentOS 7 ships an outdated version of the Kernel that does not support our eBPF functionalities (required Kernel 5.14+).

The system I'm currently using has upgraded the kernel separately, and the current kernel is 5.4.144. This kernel should support eBPF, right? Ithink the fault happend because of the version issue of libc（or glibc ？)

[mariomac]

Hi @kazu12 yes, this kernel version supports eBPF, but not all the functionalities that Beyla use. Anyway it's true that Beyla should at least start. This seems caused by an older glibc version than the version that the Go compiler uses in our CI.

Could you try compiling Beyla from CentOS7 and see if it works? It should be as simple as:

make compile

If you have Docker, you can compile it by copying the following Dockerfile_centos7 in the project root and build a Beyla image with:

docker build -f Dockerfile_centos7 -t beyla:centos7 .

Dockerfile_centos7:

# Build the autoinstrumenter binary
FROM centos:7 as builder

# TODO: embed software version in executable

RUN echo "using TARGETARCH: $TARGETARCH"

RUN yum clean all

Hi @kazu12,

One other option is to see if you can upgrade the libc on your distro. I was able to do that on an older Debian version when I was testing some functionality.

Adding a comment one this one. When I run the latest version of ./beyla (1.0.2) on an amd machine:

uname -r

5.10.0-26-cloud-amd64

I get:

root@ip-10-15-2-6:/opt/beyla# ./beyla
./beyla: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./beyla)
./beyla: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./beyla)

And the glib version:

ldd --version

ldd (Debian GLIBC 2.31-13+deb11u7) 2.31

The system is running debian 11 - bullseye.

However when I run on an arm64 equivalent I get this I don't get the same error even though it has the same libc version:

ldd --version

ldd (Debian GLIBC 2.31-13+deb11u7) 2.31

Hi @teliov, if you have go in your system, as a workaround, could you try installing Beyla with:

go install github.com/grafana/beyla/cmd/beyla@latest

?

[grcevski]

I think we need to start producing statically linked binaries or build a distribution version for the older GLIBC.

[teliov]

Thanks @mariomac , the installation via go binary doesn't produce this error.
