问 /usr/include/c++/8/cstdlib:75:15:致命错误: stdlib.h:没有这样的文件或目录

EN

我是linux的初学者，当我在我的raspberry pi上运行我的第一个程序"HELLOWORLD“时，出现了这个警告：

pi@raspberrypi:~/raspitest $ g++ test.cpp -o test
In file included from /usr/include/c++/8/ext/string_conversions.h:41,
                 from /usr/include/c++/8/bits/basic_string.h:6400,
                 from /usr/include/c++/8/string:52,
                 from /usr/include/c++/8/bits/locale_classes.h:40,
                 from /usr/include/c++/8/bits/ios_base.h:41,
                 from /usr/include/c++/8/ios:42,
                 from /usr/include/c++/8/ostream:38,
                 from /usr/include/c++/8/iostream:39,
                 from test.cpp:1:
/usr/include/c++/8/cstdlib:75:15: fatal error: stdlib.h: No No such file or directory
 #include_next <stdlib.h>
               ^~~~~~~~~~
compilation terminated.

我没有使用任何make工具，只是通过vim编写代码并运行以下命令： pi@raspberrypi:~/raspitest $ g++ test.cpp -o test

stdlib.h应该位于正确的路径中：

pi@raspberrypi:~/raspitest $ locate stdlib.h
/opt/Wolfram/WolframEngine/12.1/SystemFiles/Links/ArduinoLink/Resources/CSource/avr-libc/1.8.1/avr/include/stdlib.h
/usr/include/stdlib.h
/usr/include/arm-linux-gnueabihf/bits/stdlib.h
/usr/include/c++/8/stdlib.h
/usr/include/c++/8/tr1/stdlib.h
/usr/include/freetype2/freetype/config/ftstdlib.h

以下是我的原始代码：

#include<iostream>
#include<stdlib.h>
using namespace std;
int main()
    cout <<"hello,world" << endl;
    return 0;
}

下面是 g++ -v test.cpp 的输出

pi@raspberrypi:~/raspitest $ g++ -v test.cpp
