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
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
