The K Desktop Environment

Chapter 3. Programok

Now that KDevelop installed successfully and the most commonly used options are set, you are probably wondering if it keeps what it promises. This Chapter gives you a guideline to how programs are created using the GNU tools in general and especially what part KDevelop plays in this game.

3.1. A Fordító

The Compiler is actually the program on your system that has to be installed as a minimum to create running programs; he is the one that compiles the source code into object files and creates the program.

Normally, you would start like this: Open an editor of your choice - don't use a word-processor. Type in something like this to create the source for your first program:

 #include <iostream.h>
 
 int main(){
 
 cout << "Hello World" << endl;
 
 }
Well, actually all the program will do is to print out the string "Hello World" to your standard output . But this is just the source code for the program to be build, not the program itself. Therefore, we need a Compiler , in this case a C++-Compiler like g++. Then we can save the file with the source code, as, let's say, myprogram.cpp and invoke the Compiler with the filename (on a console):

 g++ -o myprogram myprogram.cpp
Then we can start our program- just type myprogram on the console, and the program prints out the string; then exits.
