ydb/contrib/libs/libc_compat/README.md

This library implements a compatibility layer between various libc implementations.

The rationale for the library implementation is described in https://st.yandex-team.ru/IGNIETFERRO-1439.

The code is taken from multiple sources, thus both LICENSE() and VERSION() tags are not very representative.

During development one can make use of the following mapping of OS_SDK into glibc version.

Ubuntu	glibc
24.04	2.39
22.04	2.35
20.04	2.30
18.04	2.27
16.04	2.23
14.04	2.18
12.04	2.15
10.04	2.11

Use the following commands to update the table above:

1. ya make util -DOS_SDK=ubuntu-xx -G | grep OS_SDK_ROOT | head -n 1
2. cd ~/.ya/tools/v4/$RESOURCE_ID
3. readelf -V $(find . -name 'libc.so.6')
4. Take the latest version from .gnu.version_d section prior to GLIBC_PRIVATE
