链接上的未定义符号 ___gxx_personality_v0

2021-12-18 00:00:00 gcc c g++ c++

我一直在用这个命令行构建这个未定义的符号:

I've been getting this undefined symbol building with this command line:

$ gcc test.cpp
Undefined symbols:
  "___gxx_personality_v0", referenced from:
  etc...

test.cpp 很简单,应该可以很好地构建.什么交易?

test.cpp is simple and should build fine. What is the deal?

推荐答案

使用

g++ test.cpp

相反,因为这是 C++ 代码.

instead, since this is c++ code.

或者,如果您真的想使用 gcc,请将 -lstdc++ 添加到命令行,如下所示:

Or, if you really want to use gcc, add -lstdc++ to the command line, like so:

gcc test.cpp -lstdc++

针对每个场景下产生的 a.out 运行 md5 表明它是相同的输出.

Running md5 against the a.out produced under each scenario shows that it's the same output.

但是,是的,g++ 可能会让你的世界变得更简单.

But, yeah, g++ probably makes your world a simpler place.
