1. Install C (if it isn't already present).
Cut/paste this command:

Quote:

sudo apt-get install gcc g++ gdb make manpages-dev build-essential linux-headers-`uname -r`

2. Write a "hello world" test program:

Quote:

vi hello.c

Code:

#include <stdio.h>

int
main (int argc, char *argv[])
{
  printf ("hello world\n");
  return 0;
}

3. Compile:

Quote:

gcc -g -Wall -pedantic -o hello hello.c

4. Run:

Quote:

./hello

5. You'd use probably use tools like Eclipse or make to develop projects.

not quite sure why you want to install the kernel-headers for that. You maybe meant the glibc (c standard library), which is 'libc6-dev' and contains the headers like 'stdio.h'

Thanks a lot my dears.
You are first to reply me and wise also.
I tried the code but it does not work..uname is not found.Pls tell me from basic and explaining everything.also I have Gvim text editor so is it usefull in c programming?
pls reply.

uname is a std cmd: it's possible you used single quotes(') instead of backquotes (`).

you could try this format instead

Code:

sudo apt-get install gcc g++ gdb make manpages-dev build-essential linux-headers-$(uname -r)

Also you can select "synaptic Package Manager" through "System" menu and put gcc etc. in the search bar, the relevant packages will automatically get selected and then then...

No idea what is Gvim, but I suggest you to stick to Vim for a start, if you run into problems various people will be here to help you w.r.t Vim.
Vim is there by default.

Gedit is great for all languages.

Hi Piyush ,
I think gcc comes preloaded with Ubuntu.
Give 'which gcc ' so that you can ensure whether gcc is on place.
If no gcc present you can install it using package manager or can download,compile&install.

#include <stdio.h>
main ()
{
printf ("BOss My Generation from C \n");
}
Suppose your filename is print.c,take a terminal

Method I:

YOu can compile with gcc print.c,generates a file a.out,
to compile that give ./a.out in the directory where a.out is present.

Method II:

compile with gcc print.c -o output
then run ./output instead of a.out in previous case.
you can give whatever name instead of output,u like

No it doesn't, Ubuntu lacks even the "man pages" by default!, BTW welcome to LQ.

That can be an issue if you don't have an internet connection

appilu · 01-20-2011, 05:08 AM

its right anisha, for apt a netconnection is required.
From my experience am saying without net its bored to work on linux.
