Undefined Symbol ___gxx_personality_v0 on link

Question

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

Use

g++ test.cpp

instead, since this is c++ code.

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

gcc test.cpp -lstdc++

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

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