c programming

[dsuresh]

hi,

how to compile c pragram in ubuntu. is it need any compiler or application.
help me briefly .. new to c program

[Lakshmipathi]

To compile,

#gcc filename.c

To run,

#./a.out

Edit:
gcc compiler comes as default in most distros.so you won't need any new compiler.

Another way is

$gcc -o prog prog.c
$./prog

[vijay_kernel]

You need to install the compiler first like,

sudo apt-get install gcc

if gcc is installed successfully then you can compile the program by using the "cc" or "gcc" like,

cc hello.c or gcc hello.c

And you need to install the library also.

To develop on Ubuntu, I recommend you install the "build-essential" metapackage:

sudo apt-get install build-essential

That includes gcc and a host of other things.

how to create .c file and where?


no info in ebook ...

[daark.child]

You just use an editor such as VI/M, Emacs, KATE, Gedit etc. Another option is to use an IDE like KDevelop, Anjuta, Geany, Eclipse etc. You can just sotre the files somewhere in your home directory.

i have created a hello.c in desktop . how to compile in terminal.

[Lakshmipathi]

Ok....In Fedora we used to Click on,
System Tools -- > Terminal ( i guess its should be same in ubuntu )
To get into terminal,
From there go to ur file directory say(i assume ur login name is oss),

cd /home/oss/Desktop 
gcc filename.c
./a.out

HTH

If you want your programs to have a name thats more meaningful than a.out, the use the -o flag in gcc e.g.

$gcc hello.c -o hello

You would then run the program by doing

$./hello
