Hope for --enable-clocale

[flaribbit]

Hi, thanks for your awesome build. I notice that there are locale files in share/locale, but clocale is not enabled in configuration. I tried to build it but ran into a lot of errors and failed. I think this feature might be helpful to non-English-native users. Could you add this feature?

According to https://gcc.gnu.org/onlinedocs/libstdc++/manual/configure.html there are different options I can choose from. Would --enable-clocale=generic be enough, or should I consider --enable-clocale=gnu?

[flaribbit]

Thanks for your reply, but I have no idea which one is better, as far as I know, Manjaro and old MinGW use --enable-clocale=gnu, and they work fine, so I prefer gnu.

[brechtsanders]

I will try to make a build with this option, so you can test it.
What exactly doesn't work without it, and do you have a reproducible scenario?

[flaribbit]

sorry I havn't met that yet😥

[brechtsanders]

Can you try the --enable-clocale=gnu build I just released here: https://github.com/brechtsanders/winlibs_mingw/releases/tag/10.3.1-snapshot20210410 and let me know if that works better for you?

[flaribbit]

Ah, I'm wrong, it doesn't work, and it even don't visit share/locale(monitored with Process Monitor). I would appreciate it if you continue to try generic, if it still don't work, forget about it.

Here are Manjaro and MinGW's config, their language can be changed by export LANG=xx or set LANG=xx:

Are you just loooking for gcc output in your language? In that case `--enable-nls` should do. I disabled it in the past as I was aiming for highest performance and I was assuming nobody really depends on the localized output as its harder to searcjmh for translated errors and warnings online.

[flaribbit]

Yes, that's what I'm loooking for. Sorry for misleading. Turned out it’s nls, no wonder I couldn’t find anything about changing the locale or language. I agree with what you concern, maybe I should give up this idea. Thank you for your patient reply.
