Hi,
I ve installed Kubuntu 8.0 on my system.I want to do some programming on my system in C.But the gcc is not working properly.For the following program:
h.c
****
#include <stdio.h>

int main()
{
printf("HelloWorld");
}

I get the output::
h.c:2:19: error: stdio.h: No such file or directory
h.c: In function âmainâ:
h.c:6: warning: incompatible implicit declaration of built-in function âprintfâ

My apt is also not working when i do "sudo apt-get install glibc" for any package it gives the following error::


Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package glibc


What should i do:;:here is my "etc/apt/sources.list" file :->

Please tell me what to do......

Thanks in advance!!!

Probably the package has a different name. Does running apt bring the GUI? If yes, search for "C", this will bring a list of packages from which the relevant one can be picked.

OT : Some distros like Mandriva, Opensuse, PC Linux have the GUI for app management, and that is comparatively an easier way to manage installation.

'sudo apt-get install build-essential' or use synaptic.
This will install the needed devel tools, included 'libc6-dev'
which is the name for glibc on Debian based distros, e.g. Ubuntu.

Rgds
PS.: headers (file.h) are usually in "package-name"-dev

Thanks for reply!!!
I tried sudo apt-get install build-essential but it doesnt work ..the error message was..

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package build-essential

I dont have synaptic package manager on my system
what should i do know...???

hi...
My friend...
It's better to use "g++" or "c++" compiler...
because it's more better than gcc and supports many librarys and C Language ...
I tested your program with g++ and had no problems while compiling and run...
first run adept-manager:

KMenu -> System -> Adept Manager

now in adept-manager window in "Adept" menu Press the "Fetch Updates" key and wait for it to download headers...
now you can use your command for installing packages... (like "sudo apt-get install libc6"

I Hope It Be Helpful...
Bye.

Sir,
I intend to say that i ve nt got standard c library in my system i think there is no problem with gcc.Secondly, i did what you said {fetch updates}.But it has no effect, it gives the following output


sudo apt-get install libc6
Reading package lists... Done
Building dependency tree
Reading state information... Done
libc6 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.




i have got some problem with my Adept package manager which i m not able to resolve.Please help me at this point.Because my Adept doesnt work for any package. I already mentioned the output it gives ,in the former post when i try to install something.

Hi...

i tested your program a lot with gcc...
and when i removed the << printf("HelloWorld"); >> line your program compiled successfuly .
i know printf function is in the stdio.h header but i dont know why it dont have this useful I/O function !!!!
but g++ have it...
you can use it as a good compiler...
it can compile standard C programs too...
but if you dont want to use it you have only one more way...
you have to download the newest gcc package and install it again...
you can search and download it as DEB binary file in this website easily...

http://packages.ubuntu.com

my friend ...
libc was an example ...
you have to replace it with the name of the package that you want ...
and for this result
it's because you have the newest version of libc (The Example package)

ok...
now test this code for glibc (something you want)

if you want to solve your adept-manager problem first boot in recovery mode (select it from grub)
then wait for some seconds ...
OK...
Now Recovery mode is Ready...
first you have to be as root user...
for do this enter this command and then enter your password...
now enter this command and accept everything that will asks you

and now this command:

by this commands you will remove packages are not installed correctly...

ok...
it's done
now you can restart your system by this command and boot your system in normal type.
OK... Your Adept Manager repaired.

I Hope It Be Helpful

Bye.

To compile programs you need development versions.
Try 'sudo apt-get update' (will add more packages using
"address list" /etc/apt/sources.list to your list of
install candidates)
And then 'sudo apt-get install libc6-dev'

And try again 'sudo apt-get install build-essential'
and if no result do
'sudo apt-get install g++-4.2'
(which also will get you libstdc++6)

Then you at least have some of the tools.
