链接上的未定义符号 ___gxx_personality_v0
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.
