Dr. Mu has asked for the wisdom of the Perl Monks concerning the following question:

I've recently installed Inline::C on Gutsy Gibbon (Ubuntu 7.10) and have written a test program: 
use strict;
use Inline (
    C => 'DATA'
);

print add(3, 5);

1;

__DATA__
__C__
int add(int x, int y) {
    return x + y;
}

When run, it gives me the following output in STDERR:

    Looks like you need to install the C header files.

    Try 

    sudo apt-get install linux-headers-`uname -r` build-essential

    Before you go messing with Inline::C I suggest you make sure you can compile a basic C program off the command line. Can you compile hello world?

      Thanks! Installing the headers worked like a champ! Kilobytes of error messages have been reduced to a single digit: 8.

      "Before you go messing with Inline::C I suggest you make sure you can compile a basic C program off the command line. Can you compile hello world?"

      Well, no. But I'm not interested in doing anything particularly complicated — just speeding up some Perl bit-twiddling subroutines. As you suspect, this C stuff is pretty much rote imitation for me at this point. But, with this obstacle removed, I'm confident I can slog through it.

      Thanks again for your help!

        Glad it worked. The suggestion to try a command line compile was simply to make sure you had a working setup - you do so all is well. You will find an extensive C tutorial here

        As anonymous monk asks above, how did you actually install Inline::C? As a binary package? Anyway now you have C working the usual methods described in A Guide to Installing Modules should work for just about everything.

        As you note your C compiler will often spew a scary long list of errors. It pays to concentrate on fixing just the first error (or chunk or errors) as once the compiler chokes most of the rest of the output is more or less meaningless. As soon as you fix the initial problem things will either work or you will have a whole new long list of errors!
