Any supports for GLIBC_2.17 (centos 7) ?

[g0194776]

Hi all,

Currently, we are using CentOS 7.4 which uses GLIBC_2.17 by default.
What I found is that there are no matched bpftrace versions works on it recently.
What can I do? Can I rebuild bpftrace to support it? How?

Thanks a lot.

@fbs Thank you, But it does not work well for me.

The bpftrace cannot be install by yum, error output:

Where can I find the docker image for this special version of bpftrace?

[fbs]

woops, fixed the repo.

There is no docker image, that rpm is all I provide. You can build a docker image if you want.

@fbs Thanks.
