Re: Trouble with Locale

[Kenneth Adam Miller <kennethadammiller at gmail dot com>]

I should also add that the reason I believe I need it is to check the
libc tests that rust provides in order to know that libc is operating
correctly. Please

I'm adding a uclibc cross compile target for the rust compiler. I am
using the 1.0.9 version, the most up to date that crosstool allows. It
isn't so much embedded device support that is desired as it is that we
want to reduce our trusted computing base as much as possible. Musl
was another possibility, but I haven't had time to explore that route.

Can a uclibc cross compiler be compiled with locale support at all?
