#9016 — std::locale problem on Mac OSX

I get a runtime_error while porting a program to Mac OSX 10.6 with
std::locale.

#include <locale>
int main ( int argc, char *argv [] ) {
    std::locale mylocale("");
    return 0;
}

Returns an error for any locale diferent than "C":
bash-3.2$ LANG=es_ES.UTF-8 ./locale
terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid
Abort trap


Is that a Mac OSX bug? Am I doing something wrong?

Sounds like a bug. The C locale and the "" locale (user's default) 
should be supported. Anything else you can't count on, but those two 
need to be supported if I recall correctly, which I'm pretty sure I do.

Cheers & hth.,

That assumes that the user's default locale is a valid locale. The OS
won't prevent you from setting LANG etc to an invalid locale.

Which locales are valid may vary between individual systems, even for the
same architecture and OS.

This happens when GCC is not configured with locale support. See
<http://gcc.gnu.org/onlinedocs/libstdc++/manual/configure.html>, the
--enable-clocale option.

It might be that MacOS X does not support what GNU libstdc++ needs/wants to
implement fully functional std::locale. I cannot tell as I do not use that OS.
