helloworld.c无法使用100+；错误

我相信我正在处理某种腐败的图书馆。我编写了以下代码：

//helloworld.c                                                                  

#include <stdio.h>

int main()
{
  printf("Hello, world!\n");

  return 0;
}

我犯了很多错误。以下是一个示例：

FWIW，我正在运行Ubuntu11.10；最近的安装。我猜想在安装时我没有做到一些事情，但我以前从未遇到过这个问题。如果您有任何建议，我将不胜感激，并能回答您可能需要帮助我澄清/缩小问题范围的任何问题。再次感谢

编辑：谢谢你们的建议，伙计们，但我还是迷路了。我已经卸载/重新安装了libc dev bin、libc6 dev、gcc和dpkg。有人建议我问包经理crt1.o和crti.o在哪里，但我恐怕不知道怎么做

---

除了重新安装Ubuntu之外，有没有一种可靠的、暴力的方式来完全重建所有的库和头文件？如果没有，我可能会决定重新安装。

您几乎必须有一组损坏的头文件。要确认，请尝试以下操作：

extern int printf(char *, ...);
int main() {
    printf("hello world!\n");
    return 0;
}

---

如果编译得很干净，可能会导致

stdio.h

或其中一个文件损坏。如果输出二进制文件运行并产生预期的输出，那么乍一看，库本身看起来是正常的。

在11.10的干净安装上不会发生这种情况（刚刚选中）。我将删除并重新安装gcc和头文件。使用您发布的代码，我得到以下信息：hellotest.c:在函数“main”中：hellotest.c:2:警告：“main”的返回类型不是“int”/usr/bin/ld:找不到crt1.o:没有这样的文件或目录/usr/bin/ld:找不到crti.o:没有这样的文件或目录collect2:ld返回1退出状态我将main更改为int并添加了返回0；最后，get:/usr/bin/ld:找不到crt1.o:没有这样的文件或目录/usr/bin/ld:找不到crti.o:没有这样的文件或目录collect2:ld返回了1个退出状态，那么对此有什么适当的修复方法？我已经非常确定这个问题。第一个警告来自编译器，说我的main声明有点不正确。（我很快就会解决这个问题。）其余的对我来说意味着，除了损坏的头，您似乎也有损坏的库。我真的不知道该建议什么。你能强制重新安装一些基本的libc软件包吗？也许你的编译器也是如此？@FrankHarris：还有一些想法。如果你找不到

crt1.o

，有些事情很奇怪，但它解释了为什么其他程序可以工作。它们已经被链接到

crt1.o

上，或者是当它们来自的包被构建时，或者是在这之前编译它们时。您最近是否升级了系统或安装/升级了任何软件包？试着询问软件包经理哪些软件包提供了

crt1.o

和

crti.o

，并考虑重新安装。接受……如果可能晚了很多个月。上学期末，我在$PATH中添加了一些东西，基本上提供了一个额外的crt1.o。我把它从我的路径上移除，问题就解决了。

extern int printf(char *, ...);
int main() {
    printf("hello world!\n");
    return 0;
}
