Compiling C with Emacs
 
Okay, i'm trying to compile with emacs and here is my code
Code:
#include <stdio.h>
int main()
{
printf("Hello World!\n");
exit(0);
}
I go to Tools > Compile and at the bottom is this
Quote:
Compile: command -k
What I need to know is, what goes after the -k ?

Thanks

:newbie:

i do

gcc {options} sourcefilename.c

sdpeelejr 04-05-2004 09:05 PM
Okay, so I typed

Compile command: make -k gcc {options} hello.c

and it returned
Quote:
make -k gcc {options} hello.c
make: *** No rule to make target `gcc'.
make: *** No rule to make target `{options}'.
make: Nothing to be done for `hello.c'.

What's wrong?

Sorry for being a newbie:newbie:

Thanks

either use make or gcc not both - i like gcc as a compiler so i use it

assuming your prog is called hello type

gcc hello.c

the {options} bit before is you can add options but if you dont kown what they do just leave them out!

else type

make -k hello.c

if it doesn't work you need to put the dir infront of the name of the file - when you opened emacs and started the buffer you typed C-x C-f to get a new buffer, just put the dir name in, ie

if i had hello.c in my /home/guest dir i would type (for gcc)

gcc /home/guest

i would then get a file called a.out in the same dir as the source file... to run the program just type

./a.out

when you are in the same dir as the file

and just to add - i am a total newbie aswell, i've only had redhat for about 4 days - just stick with it

good luck

Okay, I typed Compile command: make -k hello.c and it goes
Quote:
cd /home/stevie
make: -k hello.c
make: Nothing to be done for `hello.c'.

Compilation finsished at Wed Apr 7 09:19:13
What am I doing wrong? :confused:

All I need is for this to compile into an executable so I can run the program.

Thanks!

do make hello without the .c on the end

sdpeelejr 04-07-2004 10:07 AM
Compile command: make -k hello

returned

cd /home/stevie/
make -k hello
cc hello.c -o hello
make: cc: Command not found
make: *** [hello] Error 127

:cry:

sounds like you don't have "cc" linked to "gcc", but that's another issue

just put in the following as is (no make -k)

gcc hello.c -o hello

It's really worth learning to write makefiles so that you don't have to retype longer and longer gcc lines as you work on larger projects. here's a little tutorial that babies you through it:

The OP might want to check that he does have gcc installed: I thought it was pretty standard for gcc packages to link cc to gcc for you.
