I recently installed gcc version 3.3 on Redhat 7.3 kernel 2.4.18-3. I am taking an introductory c++ class this fall and I wanted to get a head start on compiling my c++ programs. I compiled my program (without error) with the following command: g++ first.cpp It produced a file called a.out. Is this the object file? How do I convert this file into an executable file? Is linking the process used to create an executable from an object file? Forgive my ignorance surrounding this question. Any help would be greatly appreciated.
