I'm building oceanbase master on archlinux:

bash build.sh debug --init --make

Deps fetched correctly, but compilation failed as:

It looks like GLIBC version mismatch. Do you have some suggestions to overcome this error?

It seems bumping libapr to 1.7.0 can fix this issue - https://open.oceanbase.com/blog/1794247424

[tisonkun]

Successfully compiled by replacing libapr with 1.7.3.

I may try to write this troubleshooting somewhere (Wiki pages are hard to cooperate with).

You guys may investigate whether we can upgrade libapr to 1.7.3 (the only dependency is coming from deps/oblib/src/lib/restore)

For anyone stuck in this issue: You can download a copy of the source code of the libapr and recompile it, then replace the ../deps/3rd/usr/local/oceanbase/deps/devel/lib/libapr-1.a with archive file you've compiled.

oceanbase supports ubuntu24.04?
