Unable to compile simple c program in Linux Mint 15

Question

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 

Answer 1

I was having the same problem, and simply installed the g++ package and that fixed the missing include file.

sudo apt-get install g++

Answer 2

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.
