Ok, for now I am probably stuck with this one, it needs much of reading
from endless strace logs for various gtkware. I got it to include
*gettext syms and now gtk stack calls them, but that's a dead end: even
if I set all LC_/LANG properly I still get English and my debugging
musl which have locale functions with inserted printfs at beginning
show only setlocale(0, "") and that's all. Only few called with proper
arguments. I see .mo's from proper path (containing name of desired
locale, thus = "*/ru/*") are mmaped.
As for now I have no much time to test it (likely I will continue on
this one in next month or so), so I only want to resolve one issue which
still stays: is it permitted to change strftime in a way that "%x" will
return NOT American date with month in beginning, but preferred date
like "%d.%m.%Y" or similar? Will not it break any existing apps?
Thanks.
