无法在Ubuntu中编译简单的c ++程序

Question

我试图在终端中构建一个简单的程序.

#include <stdio.h>
#include <stdlib.h>
int main()
{
        printf("TESTING");
        return 1;
}

我跑了g ++ -o test test.cpp

错误:

/usr/include/features.h:356:25: error: sys/cdefs.h: No such file or directory

列表以这种方式继续.我希望有人可以指出我没有做过这项工作.

解决方案：由于之前的一些尝试，我的路径是空的。我使用以下命令创建了一条干净的路径：

export PATH= /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

编译后我的问题是程序不会显示任何结果。这是因为作为一个新的 Linux 用户，我没有意识到我需要调用前面带有 ./ 的程序。这也可以通过调用在路径中设置：

export PATH: $PATH:./
