Knoppix doesn't have gcc installed?
Or you might want to try something like sabayon.

why dont u buy a new hdd it is cheaper these days

or if u hv usb u can get ur hands on win xp usb edition no need for an hdd

[MetalheadGautham]

^^sabayon is too heavy to be run live. I recomend he try installing knoppix on the pendrive.

and I think it already has GCC installed. Why not try typing GCC in the terminal and see if the program responds with the oh so boring <you need to choose the following options> <blah blah blah> message ?

You ever used Sabayon? Do you know it comes with fluxbox?

@OP:utilize a pendrive for the time being(if u have) few distros can be booted from usb pendrive.

On Ubuntu 7.10, launch it live and in case there is no gcc by default in it, issue the command:

sudo apt-get install build-essential

This should install the packages required for C, C++ and Fortran languages and Make, etc.

@ratandeep:
below link may help installing Ubuntu on usb.get build-essential installed later.

Guys, I think he wants to know how to compile C/C++ programs in *nix.

If that is what you need. Then I think knoppix comes with gcc. So, you just write the program in any text editor. Save it wherever you want. Open the terminal. Go to the path where you saved the file. Then type

gcc <filename.c>

to compile it. Then use

./a.out

to run it.

./a.out

what is "a" here..
or its just a command..?
not having linux installed at this particular time..
so just curious about it..

also one more thing i want to ask is that when we compile a program in windows say in TC, .exe file is created.
what happens in linux??

[Pathik]

a.out is the default (executable) output file name by gcc. and you execute it using ./

Windows has a habit of making all executable files have a compulsory .exe to execute I suppose.

On Linux, any file with a +x permission is enough to be executed. Extension, name or any other property doesn't matter. (+r for readable, +w for writable and +x for executable, its as simple as this)

So a compiled file may be called XY, or XY..XZ or XX.YY.ZZ, it doesnt matter, it should have the +x permission set and it can be executed.

assembler.output
I believe it's an elf binary though the name suggests otherwise. See http://en.wikipedia.org/wiki/A.out_(file_format)

[Manshahia]

so..
tried to compile my first program in Linux..
i want to knw that format of C/C++ remains same whether it is done in linux or windows..
second thing i made a simple program and when tried to compile using GCC it said cudnt find conio.h, iostream.h, blah blah blah....

[aditya.shevade]

The syntax remains the same as long as you use standard C/C++ code and compilers.

[Faun]

Turbo C program needs some polishing before trying on ANSI C compliant GCC compiler

Read any ANSI C book and u will find urself right at home with GCC

[FilledVoid]

i want to knw that format of C/C++ remains same whether it is done in linux or windows..

The Format / Syntax C/C++ doesn't change based on the Operating System you use but rather the Compiler you use.

second thing i made a simple program and when tried to compile using GCC it said cudnt find conio.h, iostream.h, blah blah blah....

Because conio.h is not part of the C standard. I'm not sure about iostream though.

[aditya.shevade]

^^ Isn't TurboC (Borland Compiler) compatible with ANSI C and GCC with ISO C/C++?

As far as I know, people use ISO standard these days....

@Manshahia, iostream.h is no longer iostream.h according to ISO standards (which are used by GCC, MingW32, etc) but it is plain iostream now. remove the .h extension.

[QwertyManiac]

Btw,you shouldn't be using gcc for compiling a C++ program. Use g++ for that purpose, else it'll spew out some garbage.

[aditya.shevade]

Isn't g++ part of GCC? (I read in the repository that the package name was gcc-g++-x.x.x.x)

[mehulved]

Well, what Harsh meant was gcc=GNU C Compiler
GCC=GNU Compiler Collection
There's a difference between gcc as a program and GCC suite of compilers.

One more "did not work" person. Like we are GOD.
Can you please tell what did not work?
I hope you didn't expect a full blown IDE to pop up when you typed gcc at the command prompt.

[Ratnadeep]

hello friends,

I am really thankful for your advice and i am now capable of compiling all my c programms in knoppix.
From last 4 moths i am using my pc without hard disk and with no problem or limitation in my work.
Thanks Knoppix.
Now, I am fan of KDE and I liked it most.

Again THANKS Friends.
