/ usr / bin / ld：client：隐藏符号`__dso_handle' [英] /usr/bin/ld: client: hidden symbol `__dso_handle'

问题描述

命令我用过： g ++ -o client Client.cpp - L.

 <$ c  
在/usr/lib/gcc/i486-linux-gnu/4.4.3/crtbegin.o中的$ c> / usr / bin / ld：client：隐藏符号`__dso_handle'被DSO引用
 / usr / bin / ld：最终链接失败：输出的非代表性部分
 collect2：ld返回1退出状态
  

如何解决这个错误？

解决方案

隐藏符号`__dso_handle'位于/ usr / lib /gcc/i486-linux-gnu/4.4.3/crtbegin.o被DSO引用

推测 libprint.so 是引用DSO。您可以确认：

  nm ./libprint.so | grep __dso_handle 
  

如果产生 U __dso_handle 输出，您的 libprint.so 构建不正确（很可能您使用 ld -shared 来链接它。这样做，请使用编译器驱动程序，例如 g ++ -shared ... ）。

I am trying to link with a shared lib in my C++ program.

command I used: g++ -o client Client.cpp -L. -lprint

Following is the error:

/usr/bin/ld: client: hidden symbol `__dso_handle' in /usr/lib/gcc/i486-linux-gnu/4.4.3/crtbegin.o is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status

How can I resolve this error?

解决方案

hidden symbol `__dso_handle' in /usr/lib/gcc/i486-linux-gnu/4.4.3/crtbegin.o is referenced by DSO

Presumably libprint.so is that referencing DSO. You can confirm with:

nm ./libprint.so | grep __dso_handle

If that produces a U __dso_handle output, your libprint.so was built incorrectly (most likely you used ld -shared to link it. Don't do that, use the compiler driver, e.g. g++ -shared ... instead).
