C++ Linker Errors from GCC Compiler

The following errors come from compiling a simple C++ program using the command:

gcc simple-cpp-program.cpp -o scppp

The error typically looks like:

Undefined symbols for architecture x86_64: "__ZNKSt7__cxx1112basic_stringIcSt11char", referenced from: __ZStplIcSt11char_S9_ in ccBDqkud.o . . . [a lot more here] . . . "___gxx_personality_v0", referenced from: Dwarf Exception Unwind Info (__eh_frame) in ccBDqkud.o ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status

If you really used the "gcc" command as shown above, then the first thing to try is to use g++ instead of "gcc":

g++ simple-cpp-program.cpp -o scppp

Following is a non-exhaustive list of the nonsense labels (they are appropriately called C++ mangled names) that I get just by using stdio to files and the screen.
