The command clangis for C, and the command clang++is for C++.
命令clang用于 C，命令clang++用于 C++。

Also, for posterity -- Clang (like GCC) accepts the -xswitch to set the language of the input files, for example,
此外，对于后代 - Clang（如 GCC）接受-x开关来设置输入文件的语言，例如，
$ clang -x c++ some_random_file.txt

I do not know why there is no answer directly addressing the problem. When you want to compile C++ program, it is best to use clang++. For example, the following works for me:
我不知道为什么没有直接解决问题的答案。当你想编译 C++ 程序时，最好使用clang++. 例如，以下对我有用：
clang++ -Wall -std=c++11 test.cc -o test
If compiled correctly, it will produce the executable file test, and you can run the file by using ./test.
如果编译正确，它将生成可执行文件test，您可以使用./test.
Or you can just use clang++ test.ccto compile the program. It will produce a default executable file named a.out. Use ./a.outto run the file.
或者你可以只用它clang++ test.cc来编译程序。它将生成一个名为a.out. 使用./a.out运行该文件。
The whole process is a lot like g++ if you are familiar with g++. See this postto check which warnings are included with -Walloption. This pageshows a list of diagnostic flags supported by Clang.
如果你熟悉 g++，整个过程很像 g++。请参阅此帖子以检查-Wall选项中包含哪些警告。此页面显示了 Clang 支持的诊断标志列表。

I've had a similar problem when building Clang from source (but not with sudo apt-get install. This might depend on the version of Ubuntu which you're running).
我在从源代码构建 Clang 时遇到了类似的问题（但不是使用sudo apt-get install. 这可能取决于您正在运行的 Ubuntu 版本）。
It might be worth checking if clang++can find the correct locations of your C++ libraries:
可能值得检查是否clang++可以找到 C++ 库的正确位置：
Compare the results of g++ -v <filename.cpp>and clang++ -v <filename.cpp>, under "#include < ... > search starts here:".
比较的结果g++ -v <filename.cpp>和clang++ -v <filename.cpp>，在“这里的#include <...>开始搜索”。
