Unless there is money attached? I'll respond urgently for cold hard cash

Seriously though, can you execute these commands from the shell (in the directory where your file is) and paste the results. Please do not quote them in part - paste the whole output:

Code:

ls -l filename.c
which gcc
gcc --version

Finally, if it is not too long, please insert the contents of the filename.c file.

Please enclose all these things in [code] tags to aid readability.

And please provide the exact error. Futher there is a dedicated programming section at LQ, where your question might have fit better.

Hi, chris
Thanks for the help.
i am the first in my college to execute any c program on Linux but The problem is i am not able to use the function of other library such as <conio.h>
and not even the scanf();
it is saying that no detail is given for it.
please help me.

conio.h does not exist under linux in any widely acknowledged state. you need to use suitable equivalents, e.g. the ncurses library for some of that functionality

Wim Sturkenboom · 11-09-2007, 12:01 AM

For scanf, you have to include stdio.h

Code:

#include <stdio.h>
int main (int argc, char * argv[])
{
int i;

    printf("Enter a number: ");
    scanf("%d",&i);
    printf("You entered: %d\n",i);

    return 0;
}

Compile with gcc -Wall myfile.c -o myfile and run with ./myfile.

Code:

wim@desktop1:~$ ./myfile
Enter a number: 55
You entered: 55
wim@desktop1:~$

If the compiler complains about stdio.h, your configuration is broken in some way.

PS
There is a conio for linux, but it seems to be a wrapper around ncurses. Search for linux conio

Thanks for the help but i have one more problem.
i am not able to use the simple code like
getch();
in my program.
same error messege is comming no defination is given for the getch();
what must be done to avoid the same.

acid_kewpie · 11-11-2007, 05:38 AM

i think you need to start looking at documentation a little more... http://www.hmug.org/man/3/getch.php

Erh.. in the interest of science.. what college are you in?

Moved to Fedora forum where this is more suitable and changed the title to something more suitable as well, instead of "Urgent" which doesn't describe your post or question whatsoever.

Mohammed Akram · 11-13-2007, 06:26 AM

I am from Allana college pune.
May i know something about u...... ?

wet · 11-13-2007, 10:55 AM

if you have a problem with some function, just type

Code:

man function

should provide you with alot of info about the function - which #includes you need, arguments, return values, behavior etc
(and dont tell me man pages are ugly!

)

Hi!

This is because getch() is defined in conio.h, which is not an ANSI C library.
If you include #include <stdio.h> you can use getchar()
There are some differences between getch() and getchar() but I think this can help you.
