Can'；t编译和链接程序时发出叮当声

我最近在Ubuntu系统上编译了Clang2.9（来自）。我在编译和链接简单程序时遇到问题。有人知道如何解决这个问题吗？以下是我看到的输出：

a@ubuntu:~/Desktop$ clang add.c

叮当声：错误：链接器命令失败，退出代码为2（使用-v查看调用）

听起来您的链接器脚本有问题。但是上面的ld行不包含特定的链接器脚本，因此应该使用默认的链接器脚本（只需键入

ld-v

）

-L-L/../../../..

这看起来确实有点奇怪。虽然不知道它是从哪里来的，但在你的原始行中看不到它。也许你的装置坏了

执行一个

gcc-v add.c

并比较调用

/usr/bin/ld

的行。也许可以把它添加到问题中。

谢谢你的帮助。原来

/usr/bin/ld

被另一个文件覆盖了。我不确定这是怎么发生的，但是通过调查

gcc-v add.c

的输出，我能够做出这个决定。最后，我更换了/usr/bin/ld，使一切正常工作。
