Upstream issue opened at tttapa/docker-arm-cross-toolchain#5
from kiwix-build.

I'm looking to recompile the toolchain from https://github.com/tttapa/docker-arm-cross-toolchain
The current version already have CT_GLIBC_V_2_27=y
I haven't found a option for GLIBCXX.
Maybe we should open a issue upstream, it seems to me a bug that we need glibc3.4 as it is a deliberate choice to have glibc2.27 (see tttapa/docker-arm-cross-toolchain#2 (comment))
from kiwix-build.

I've seen that comment and the release notes which mentions 2.27 as well.
GLIBCXX comes with stdlib which comes with GCC.
This toolchain properly uses glibc 2.27 but how those GLIBCXX symbols are brought in is beyond my understanding.

A objdump -p libzim.so.8.2.1 on the aarch64_bionic release shows me:

So we properly set GLIBC to 2.17
The problem is GLIBCXX
Can you share me your working libzim (rebuild with previous toolchain) ?

So we have mostly the same version of GLIBCXX.
Do you have more information of how auditwheel checks symbols and what is expected ?

From this line : https://github.com/pypa/auditwheel/blob/ebd4bc0de49394adcad557532eb19fe6598cd886/src/auditwheel/policy/manylinux-policy.json#L286
It seems we many linux 2_28 accept GLIBCXX up to 3.4.24 on aarch64.
Broken libzim has GLIBCXX 3.4.26 and 3.4.29

Faulty symbols are:
_ZNSt7__cxx1118basic_stringstreamIcSt11char_traitsIcESaIcEEC1Ev@GLIBCXX_3.4.26
_ZNSt7__cxx1119basic_ostringstreamIcSt11char_traitsIcESaIcEEC1Ev@GLIBCXX_3.4.26
