View Full Version : problem compiling Hello World!

January 2nd, 2007, 12:30 AM
lol...so yeah im a n00b to ubuntu!! i just tried to get my very first hello world program to compile using gcc, and here is the code:

#include <stdio.h>

int main() {
printf("Hello World!");
return 0;

and I tried compiling it using 'gcc -o test test.c' but it complained that it couldn't find stdio.h....i think i need to specify where the includes are, but where are they? i dont know myself! someone pls. hellllllllllppppppppppppp

Try to remove the .h on the include, so it looks like:
#include <stdio>
that should fix it. I dont believe that you need the .h at the end in Linux.

thanks for that...so i did the updates and it works!! many many fanks...and i guess we do have to add the ".h" because otherwise it complains that it cannot find the file

You keep the .h in the header, but make sure you install the package


which will actually install the missing headers. The only time you drop the .h is for certain standard C++ includes, never for a C include.

It sounds like you all only installed the compiler, but no other necessary files for building and compiling software.

sudo apt-get install build-essentialwill install all the important files for you.
