我目前正在尝试使用 Anjuta 来熟悉 C++。我尝试Hello World在 -file 中运行一个简单的程序main.cc：
#include <iostream>
int main()
{
std::cout << "Hello world!" << std::endl;
return 0;
}
但它没有成功完成，我收到了以下内容config.log：
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by foobar_cpp configure 0.1, which was
generated by GNU Autoconf 2.69. Invocation command line was

解决方法是安装g++。
sudo apt install g++
这是必要的，因为 IDE 仅仅提供了查看代码的界面，最后它运行一个 C++ 编译器来编译程序。
