下面的代码失败,我已经试过除了C
任何区域:
#include <locale>
int main() {
std::locale::global(std::locale(""));
return 0;
}
建有(-std=c++0x
似乎没有任何效果,还试图-ansi
具有相同的结果):
g++ -ggdb -Wall -std=c++0x solaris_locale.cc
g++ -ggdb -Wall solaris_locale.cc
失败:

我会承担的Solaris C++语言环境的支持是不完整/断。
什么是默认的语言环境? –
你能举例说明你得到的结果吗?例如,如果你输入“ä”(c3 a4),你得到的是哪个字符(和数值)而不是“Ä”(c3 84)? – SHR
我的默认语言环境是en_US.UTF-8。以下是在Solaris上了把语言环境的命令:LANG =的en_US.UTF-8 LC_CTYPE = “是en_US.UTF-8” LC_NUMERIC = “是en_US.UTF-8” LC_TIME = “是en_US.UTF-8” LC_COLLATE =“en_US.UTF-8” LC_MONETARY =“en_US.UTF-8” LC_MESSAGES =“en_US.UTF-8” LC_ALL = en_US.UTF-8 – user1565291
