Boost-filesystem std::runtime_error: locale::facet::_S_create_c_locale name not valid failure on Xamarin.Android

[Shirley Gong <sgong@…>]

On Xamarin.Android with boost 1.52.0, I'm getting locale::facet::_S_create_c_locale name not valid when calling system_complete where the locale is set to locale -c.

This failure occurs both when using Xamarin binding with .jar library and when using PInvoke mechanism to call native C library directly.

Is this related to #8930 boost::path::root_directory() throws locale::facet::_S_create_c_locale name not valid? or #8352 Boost-filesystem std::runtime_error: locale::facet::_S_create_c_locale name not valid failure on OpenBSD?

Replying to viboes:

This is very similar to #8930 except it's happening on Android (particularly, when developing Android apps with Xamarin).

Calling std::setlocale(LC_ALL, "C"); does not solve the problem. I had to call setenv("LANG", "C", 1); to get rid of the exception.

Sorry I meant similar to #8352.

Hi Shirley,

1.56.0, which should ship in a few days, has numerous fixes for Android and Filesystem. Is it possible for you to test against it? The files for 1.56.0 RC3 are available at ​http://boost.cowic.de/rc/ (Look down near the bottom of the list).

Thanks,

I'm marking this "fixed" since it appears to be the same as reported in several other tickets that have been fixed for Boost 1.57.0, and have been tested on Linux.

If this is still failing in the 1.57.0 release, please reopen the ticket and supply a simple test program that fails.

Thanks,
