I have installed Clang by using apt-get in Ubuntu, and I can successfully compile C files using it. However, I have no idea how to compile C++ through it. What do I need to do to compile C++?
我已经在Ubuntu中使用apt-get安装了Clang，我可以使用它成功编译C文件。但是，我不知道如何通过它编译c++。我需要做什么来编译c++ ?

The command clang is for C, and the command clang++ is for C++.
命令clang是C的，命令clang++是c++的。

Also, for posterity -- Clang (like GCC) accepts the -x switch to set the language of the input files, for example,
同样，对于后代——Clang(像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这个问题的答案。当您想要编译c++程序时，最好使用clang++。例如，以下对我来说是适用的:
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测试，您可以使用./test运行该文件。
Or you can just use clang++ test.cc to compile the program. It will produce a default executable file named a.out. Use ./a.out to run the file.
也可以用clang++ test。cc编译程序。它将生成一个名为a.out的默认可执行文件。使用。/。出去运行文件。
The whole process is a lot like g++ if you are familiar with g++. See this post to check which warnings are included with -Wall option. This page shows a list of diagnostic flags supported by Clang.
如果你熟悉g++，整个过程很像g++。请参阅本文以检查在-Wall选项中包含哪些警告。这个页面显示了Clang支持的诊断标志的列表。

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).
在从源代码构建Clang时，我遇到了类似的问题(但是没有sudo apt-get安装)。这可能取决于你正在运行的Ubuntu版本)。
It might be worth checking if clang++ can find the correct locations of your C++ libraries:
如果clang++ +能找到您的c++库的正确位置，这可能是值得检查的:
Compare the results of g++ -v <filename.cpp> and clang++ -v <filename.cpp>, under "#include < ... > search starts here:".
比较g+ -v <文件名的结果。cpp> 和clang+ -v <文件名。cpp> ，在"#include <…">搜索从这里开始:”。
