I'm trying to teach myself C and I'm having trouble compiling my first
program. This is following the C Tutorial at
<http://www.physics.drexel.edu/courses/Comp_Phys/General/C_basics/c_tutorial.html>.
My first program, a simple "Hello World", is as follows
#include < stdio.h>
Remove the space character between the "<" and stdio and try again.
void main()
{
printf("\nHello World\n");
}
I go to a console and type gcc hello.c as stated in the tutorial and get
the following error spit out at me -
hello.c:1:20: stdio.h: No such file or directory
hello.c: In function `main':
hello.c:4: warning: return type of `main' is not `int'
well, I did a whereis on stdio.h and its in /usr/include - any ideas on the
problem? I know this might be a bit off-topic, and btw I'm running RH 8.
Thnx folks,
~Christopher
Also, gcc hello.c will generate an executable called a.out. If you want
the executable to be called "hello" you should use gcc -o hello hello.c
instead.
To execute you would type ./hello and press the enter key.
