boost :: filesystem :: path(std :: wstring)抛出异常 [英] boost::filesystem::path(std::wstring) throw exception

问题描述

此代码:

boost::filesystem::is_directory("/usr/include");

做得好.

这两个代码:

boost::filesystem::is_directory(L"/usr/include");

引发异常:

终止在抛出一个'std :: runtime_error'
的实例什么():语言环境::方面:: _ S_create_c_语言环境名称无效

terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid

推荐答案

1. 在Linux上不要使用宽字符串.您不需要它们.

2. 它尝试将宽字符串转换为普通字符串会发生什么情况，为此创建一个语言环境，并且该语言环境可能未在您的系统中配置.

1. Don't use wide strings on Linux. You don't need them..

2. What happens that it tries to convert wide string to normal one and for this creates a locale and probably this locale is not configured in your system.

输出命令:

locale 
locale -a

GCC-4.6尚未发布;-)，请检查这是否适用于普通编译器.libstdc ++可能无法很好地构建.

GCC-4.6 wasn't released yet ;-), check if this works with ordinary compiler. Probably libstdc++ wasn't build well.
