macOS Help beginner programer, can't get my terminal to compile.

[sg001]

Hi could someone please have a look at the following steps to see if there is something I'm missing.

1/ I have d/lded xcode (current) and installed command line tools.

2/ for some reason edit is not opening in my terminal window.

ie I type "gedit hello.c"

output:- bash:gedit: command not found

but I just use pico and it seams to work i.e.

"pico hello.c"

and it opens a pico editing window.

secondly the compiler does not seem to work in terminal.

ie/

i create a new file "mkdir hello.c"

"cd hello.c"

now i am in hello.c

next step

"pico hello.c"

and i type this simple code

#include <stdio.h>

int main(int argc, char * argv[]){

printf("Hello World!\n");
printf("Goodbye World!\n");
return 0;
}


now I save by

^o

and save file "hello.c"

now back to terminal still in file hello.c

"gcc -Wall -Werror -O -o hello hello.c"

output:

i686-apple-darwin11-llvm-gcc-4.2: hello.c: No such file or directory
i686-apple-darwin11-llvm-gcc-4.2: no input files"

???

This is really annoying me I feel I have tried everything

please please help. Thanks

right before you try

gcc -Wall -Werror -O -o hello hello.c

please type

pwd
ls *.c

and post the results here it doesn't look like you are in the right working directory when you issue the gcc command.

Gedit is the official text editor of the GNOME desktop environment. It doesn't come standard on OS X. You can get/compile it yourself with MacPorts, Homebrew or other alternatives.
Gedit Mac OS X packages : http://ftp.gnome.org/pub/GNOME/binaries/mac/gedit/3.2/

hello.c helloworld.c

123.c:
iapple

hellohello.c:
123.c hellohello.c

iapple.c:


pls note I have tried doing this with a few different file names as I have tried to get it working a few times.

Thanks.

Open Terminal and cd into your directory where your .c file is and type :

gcc -Wall -Werror -O -o hello

then press tab to see if you see your hello.c file. If you do see it press h and tab again. Bash will autocomplete.

balamw asked for the result of the pwd command. The result will be a POSIX style path using the slash / as the separator for directories eg /path/to/some/folder.

Example :

/Users/test/Desktop/hello.c

You're not helping yourself by giving your folders the same name as source files. In general that can be a bad idea. If you want to reinforce that the folder has a C file in it, you could call it "hello_c" but don't call it "hello.c" that is a surefire path to confusion.

Ok I figured it out now thanks for the help.

I think thats what I was confused about.. I thought the folders had to be the same name as the c file.
