ANSI C Header Files

["Mark" <markh at cqm dot co dot uk>]

Hi,

This is probably a really simple problem to all C and linux experts out
there, but I don't have a clue how to solve it, and so that is why I've
posted here :)

In the past few days, I replaced a linux machine on the net.  The old
machine was an SX-25 running an install of Slackware Linux release 3.5
(kernel 2.0.36) with most program developement tools on it (gcc and all the
other stuff that goes along with program compilation and development).  I
had no problems compiling an eggdrop bot on this machine - the ./configure
script ran with no problems at all, and it all compiled nicely.

Now, the new machine is an Intel Celeron, with Slackware Linux 4.0 (kernel
2.3.33).  I have purposely installed ALL packages in the program
developement package of slackware 4.0 (appart from the svgalib package,
which isn't needed cause the machine is a server and just sits in the
corner).

I now attempt to compile eggdrop on this machine (running the ./configure
scripts to start with), and I get this error message:

configure: error:

  Your system must support ANSI C Header files.
  These are required for the language support.  Sorry.

So the obvious problem seems to be: I have no ANSI C header files installed.
However, I have no clue as to what these are, where to find them, where to
download them, and how they should be installed.. and the other question
that puzzles me is... why do I get this problem with Slackare 4.0 and not
Slackware 3.5 ?

Ok, I hope someone can point me the correct direction here... cause this
seems like such a simple problem, and yet I don't know how to solve it :(
