Locales activation on buildroot based on gclibc

Question

Could anyone help to activate locales on gclibc-buildroot? My system works fine, but there is problem. I don't see any russian letters (I need ru_RU of UTF-8 and CP1251).

I did:

System configuration -> Generate local data (en_US, ru_RU)
(*) Copy gconv libraries -> <empty> (all)

Some time before I successfully built buildroot on uclibc, where I used uclibc-menuconfig for settings of locales. But there is no gclibc-menuconfig for gclibc...

Answer 1

The problem appeared due to glibc upgrade to 2.27 version. There were changes in locale (alt names support). Buildroot's host version of localedef utility, which is used to compile locales, is uncompatible with locale definitions in new glibc.

You could downgrade glibc back to 2.26 for the workarond:
