If necessary, compile
again until you get a fresh prompt with no feedback. GCC delivers only bad news; if
things work, it just does its thing.
If you look in the directory you will see a new file called hello with no extension. Now
you can run the program:
./hello
Hello, World.
What did you do? You saved the source code with a .c extension to note what language
this code is written in. The compiler created the executable hello (the name specified by
the ??“o option), and then you executed the program. Because the program is not located
in one of the standard executable directories, usr/bin or /usr/local/bin, you must use
the dot-slash execute command in the directory where the program is located.
Additional GCC language front ends exist for Pascal, Modula-2, Modula-3, Mercury,
VHDL, and PL/I; these are developed by teams separate from the GCC team and are not
available via YaST. The Objective-C++ component is also missing from SUSE. You can
access these languages at http://gcc.gnu.org/frontends.html.
CHAPTER 28 Programming Tools 582
Managing Collective Software Development with
CVS and Subversion
The original revision control system (rcs) utility has features to manage small application
projects, but when an application grows larger or is maintained by several developers, a better
tool is needed.
