Have you considered using an IDE such as Code::Blocks. That way the task of compiling multiple file projects would be somewhat simpler :)

EDIT: Or were you specifically wanting to do it from the command line?

Use the concept of Makefile for this...although you can do without it but its worth you know that...other wise use as below

Assuming all files are present in same directory:
g++ -c -I. MyHeader.cpp -o MyHeader.o
g++ -c -I. main.cpp -o main.o
g++ -o Output main.o MyHeader.o

Hope this solves your problem
