Hello,
Am new to Linux. For a few days used Zenwalk Distribution. Now have switched over to Ubuntu. I installed Ubuntu 7.10(Gutsy Gibbon). When I try to compile my C programs, none of the header files are being recognized. Any suggestions??
Thank You.

What exactly is the error?

Have you installed build-essential?

Hello. Thanks for the reply and sorry for the delay. Well for a better picture I have included below both the program I typed and the errors it showed, as in the terminal. Could you please specify what "Build Essential" is? Shall try to find through Google if possible. Thank You.

PROGRAM:
#include<stdio.h>
main(void)
{
printf("Hello\n");
return(0);
}

ERROR MESSAGE IN TERMINAL:
anikethan@anikethan-desktop:~$ gcc 1.c
1.c:1:18: error: stdio.h: No such file or directory
1.c: In function ‘main’:
1.c:4: warning: incompatible implicit declaration of built-in function ‘printf’
anikethan@anikethan-desktop:~$

/usr/include/stdio.h is provided by the package libc6-dev. I think that if you install the virtual package build-essential as Mark suggested, this should be brought in as a dependency. i.e. open synaptic and install the package build-essential, and it will automatically install what you need.

Hello,
Thank you for the reply. Have got it working by installing Build Essential as suggested.
