You did it right the first time. If you want to compile (link) a C++
program, you use g++. gcc is used to compile (link) C programs.

gcc will call the C++ compiler to turn your .cpp file into a .o file,
but when it runs the linker, it links as though you have a C program. It
does this because you told it to (by running gcc, not g++). If you call
it as g++ it will link in the C++ libraries.
