编译stdio.h / iostream时无效的参数错误

Question

由于标头内部出现某些错误，我突然无法编译包含这些标头文件的任何内容。我以前从未遇到过这个问题，我什至不知道该错误意味着什么。任何帮助表示赞赏！

该代码只是下面显示的hello world程序，但是编译时，出现gcc和g ++的以下错误：

// test.c
#include <stdio.h>

int main(int argc, const char *argv[]) {
    printf("%Hello, world!\n");
  return 0;
}

// test.cpp
#include <iostream>

int main(int argc, const char *argv[]) {
  std::cout << "Hello, world!" << '\n';
  return 0;
}

gcc test.c
In file included from test.c:1:0:
/usr/include/stdio.h:27:10: fatal error: /usr/include/x86_64-linux-gnu/bits/libc-header-start.h: Invalid argument
 #include <bits/libc-header-start.h>
          ^~~~~~~~~~~~~~~~~~~~~~~~~~

这实际上是一个奇怪的错误，请尝试重新安装库，即libc6-dev-i386：

sudo apt-get install gcc-multilib

或

sudo apt-get install libc6-dev:i386
