How to compile this simple program in GNU emacs

[ravi]

Hi,

I typed in the following code "newone.c" in emacs
#include <stdio.h>
int main()
{
  int i;
  printf("enter i");
  scanf("%d",&i);
  printf("\nthe value entered is %d",i);
  return 0;
}

Then i did M-x compile
gave the command : gcc -o newone newone.c
Then again M-x compile and ./newone

Now emacs displayed another buffer in "compilation mode" like this

-*- mode: compilation; default-directory: "~/Desktop/new/" -*-
Compilation started at Mon Jan 28 07:19:01

./newone
enter i


I have entered 45.

Now here I when I press <RETURN>, it is saying "No error here". But
how do I send in the value 45,  without pressing <RETURN>

enter i45<unable to press enter>

I am also unable to press <SPACE>, <BACKSPACE>

Please help me. I looked in compilation mode manual and emacs manual
but could not figure out.

Should I be pressing in some key sequence ?

Please let me know.

Thanks & Regards,
ravi.

To run your program after compilation, I think it's better to open an
OS shell and run it there. Either "M-x shell" to get a shell in Emacs,
or just access the command line in the usual way of your OS.

Don't.  M-x compile is not intended for running interactive programs,
it's intended for compilers, Grep, and other similar tools that
produce output, such as error messages, in well-known format, which is
parsed by Emacs in order to display the portion of the file which
produced the error message.

Just look up gdb in the manual and use that. The multi-window gdb is
very good inside emacs IMO.

Try this Makefile

run: newone
<tab>  echo -e "45\n" | ./$@

newone: newone.c
<tab>  gcc -o $@ $<

put it in directory where your newone.c and type M-x compile.
