C++ clang应用程序的问题

我正在使用clang库构建一个应用程序，我运行到 如果有人能给出一些方向，这将非常有帮助

./a.out/home/nmahew/Desktop/algorithms/array.cpp给出

我的包含搜索目录如下

包括。。。搜索从这里开始： 包括搜索从这里开始： /usr/include/linux /usr/lib/gcc/i686 redhat linux/4.4.3/include /usr/include/c++/4.4.3 /usr/include/c++/4.4.3/backward /usr/include/c++/4.4.3/i686-redhat-linux /usr/本地/包括 /usr/包括 搜索列表结束。 而char_traits.h在/usr/include/c++/4.4.3/bits/中，我使用 Fedora 12 32位系统。

我的代码列在下面

错误显示模板类char_traits不存在。这一个实际上是在char_traits.h中定义的，不包括在array.cpp中

尽管在该文件中，它的内容如下：

/** @file char_traits.h
*  This is an internal header file, included by other library headers.
*  You should not attempt to use it directly.
*/

---

但您仍然可以尝试将其包括在内，让叮当高兴。

欢迎使用堆栈溢出，@nmahew！我尽我所能重新格式化代码。代码应缩进四个空格；您不需要使用会弄乱格式的。而且，一般来说，比起HTML标记，更喜欢标记语法；结果可能不会那么令人惊讶：

/** @file char_traits.h
*  This is an internal header file, included by other library headers.
*  You should not attempt to use it directly.
