fedora上的gcc链接器错误：未定义引用 [英] gcc linker errors on fedora: undefined reference

问题描述

我试图在Fedora / gcc上编译/运行我的程序（这在Windows / MSVC上正常工作）。编译是好的现在，链接似乎是一个问题。根据症状和此后未定义的引用`__gxx_personality_sj0 ，在我看来问题可能在编译器/链接器结构类型中有些不匹配。

• 我刚刚卸载了我发现的所有 yum list | egrep gcc | g ++ | c ++ 使用 yum remove 和


• 然后运行 yum安装gcc gcc-c ++ 。

注意：

• 您在下面看到的所有输出都是之后的步骤。


• gcc输出的最后一行是： collect2：ld返回1 exit




• 代码是编译清洁，没有警告/错误。
几乎所有未定义的引用都是 namespace std

• 我只有一个源文件 Main.C ）。

我试图提供所有我能想到的信息，如果您需要更多信息，请告诉我。 p>

不要这样做：
  gcc -std = c ++ 0x Main.cpp 
  
 $> 
 
 $ b c> g ++ -std = c ++ 0x Main.cpp 
  
 > 
 
 
  gcc Main.cpp -lstdc ++ 
  
 
 b $ b 
底线是：请确保您在链接阶段使用g ++或-lstdc ++ 。您可以在编译阶段使用前端。
 
I'm trying to compile/run my program (which is working fine on Windows/MSVC) on Fedora/gcc. Compilation is fine now, linking seems to be a problem. Based on symptoms and this post undefined reference to `__gxx_personality_sj0, it seemed to me that the problem might be some mismatch in compiler/linker arch type. Anyway, I'm no expert so


I just uninstalled everything I found with yum list | egrep gcc|g++|c++ using yum remove and
then ran yum install gcc gcc-c++.


NOTES:


All output you see below is AFTER steps above.
Last line of gcc output is: collect2: ld returned 1 exit status
Code is compile clean, no warnings/errors.
Almost all undefined references are to names in namespace std
I have only one source file Main.C (and 2 headers).


I've tried to provide all the info I could think of, let me know if you need anymore info.

解决方案
Don't do this:
gcc -std=c++0x Main.cpp
Do this instead:
g++ -std=c++0x Main.cpp
Or do this instead:
gcc Main.cpp -lstdc++
The bottom line is: make sure that you either use "g++" or "-lstdc++" at the link stage. You can use either front end during the compile stage.
