compiling c code
greetings commrades, is there anybody who understands how to compile code using the gcc compiler built in to fc1. i assumed that the compiler itself had to be added from the cd so ofcourse i tried to add it.
greetings commrades,
is there anybody who understands how to compile code using the gcc compiler built in to fc1. i assumed that the compiler itself had to be added from the cd so ofcourse i tried to add it...but, low and behold an error ocurred while trying to install one of the rpm packages and i have no idea what packages i do and dont need(theres a load of em as u know). if anybody could even vaguely run me thru the steps of setting up and using the gcc compiler, i'd appreciate it

If you are new to Linux, I suggest you install everything. Barring that, rerun the install and perform an update. You will see development tools ... add them. As RC uses a RPM system for installation, the installer will resolve the dependencies for you.
Now to compile a program. Open a terminal window. I suggest that you then set yourself up with a place to experiment:
name>mkdir source (a place where you will put source)
name>cd source
source>mkdir firsttest (your first project)
source>cd firsttest
firsttest>touch program1.c (your first program, for example)
firsttest>gedit program1.c (good editor - knows c and hilights)
*** Put a simple program in like the famous ...
#include <stdio.h>
main(void)
{
printf("Hello World, this is my first compilation");
}
*** Save the file and exit
firsttest> gcc -o program1 program1.c (This will compile / link)
firsttest>./program1 (Well, you know what you will see)
Thats all there is to it. You can type gcc --help to see a list of what the compiler switches are. Note, this is a very simple example and will help you determine if you got all the compiler stuff loaded.
I strongly urge you to let the installer do the install for you. There are really a number of packages you need and it would be very frustrating to try to do it piecemeal if you are not familiar with the Linux programming environment.
