I am a Linux Mint 15 User.
i wanted to write simple program in C.
Below is my code.(hw.c)
#include<stdio.h>
#include<conio.h>
int main()
{
printf("Hello World");
}
But, when i try to compile it with gcc
gcc -o hw hw.c
it gives me an error
hw.c:1:18: fatal error: stdio.h: No such file or directory
compilation terminated.
I googled and found some solutions which say to install build-essential
and tried to install it
sudo apt-get install build-essintial
but it gives an error again. The error is
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
build-essential : Depends: libc6-dev but it is not going to be installed or
libc-dev
Depends: g++ (>= 4:4.4.3) but it is not going to be installed
Depends: dpkg-dev (>= 1.13.5) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
So what is wrong? What is the problem?
How to solve it?
PS.
The result of locate stdio.h is
/usr/lib/perl/5.14.2/CORE/nostdio.h
/usr/lib/syslinux/com32/include/stdio.h
I was having the same problem, and simply installed the g++ package and that fixed the missing include file.
sudo apt-get install g++
I had this situation before:
rleclerc@fvrwbp01:~# gcc -o tokens tokens.c
tokens.c:1:19: fatal error: stdio.h: No such file or directory
compilation terminated.
You wrote:
sudo apt-get install build-essintial
There's a typo. Try this instead (I guess you already did something similar):
sudo apt-get install --no-install-recommends gcc
and:
sudo apt-get install --no-install-recommends build-essential
Sometimes, proof-reading makes some difference:
The following NEW packages will be installed:
build-essential dpkg-dev g++ g++-4.7 libc-dev-bin libc6-dev libdpkg-perl libstdc++6-4.7-dev libtimedate-perl linux-libc-dev make
(...)
This fixed the error.
FWIW, Mint 17 just needs build-essential to compile C programs:
# apt-get install build-essential
Reading package lists... Done
Building dependency tree

The following extra packages will be installed:
dpkg-dev g++ g++-4.8 libc-dev-bin libc6-dev libstdc++-4.8-dev
Suggested packages:
debian-keyring g++-multilib g++-4.8-multilib gcc-4.8-doc libstdc++6-4.8-dbg
glibc-doc libstdc++-4.8-doc
Recommended packages:
libalgorithm-merge-perl
The following NEW packages will be installed:
build-essential dpkg-dev g++ g++-4.8 libc-dev-bin libc6-dev
libstdc++-4.8-dev

The package name for the C standard library is libc6. Its header files are in the development package: libc6-dev. Some Linux distributions do not have the development package installed. You need to install it yourself:
sudo apt-get install libc6-dev
Why the installation of build-essentials does not resolve the dependencies I don't know. But I think the question wasn't about the installation of build-essentials and maybe it isn't needed at all.
References:
This problem may come when you are trying from wrong directory...
I suggest you to check for directory.
Update the OS by: sudo apt-get update.
The final option is to remove the exixting gcc compiler and install the new one.
You can also try this:
g++ -o [fileName] [executable name]
