NAME
       PDL::Core::Dev - PDL development module

DESCRIPTION
       This module encapsulates most of the stuff useful for PDL
       development and is often used from within Makefile.PL's.

SYNOPSIS
          use PDL::Core::Dev;
          if ($^O =~ /win32/i) {
           warn "Win32 systems not yet supported. Will not build PDL::IO::Browser";
           write_dummy_make(unsupported('PDL::XXX','win32'));
           return;
          }


FUNCTIONS
       isbigendian

       Is the machine big or little endian?

         print "Your machins is big endian.\n" if isbigendian();

       returns 1 if the machine is big endian, 0 if little
       endian, or dies if neither.  It uses the "byteorder" ele-
       ment of perl's %Config array.

          my $retval = isbigendian();


       trylink

       a perl configure clone

         if (trylink 'libGL', '', 'char glBegin(); glBegin();', '-lGL') {
           $libs = '-lGLU -lGL';
           $have_GL = 1;
         } else {
           $have_GL = 0;
         }
         $maybe =
           trylink 'libwhatever', $inc, $body, $libs, {MakeMaker=>1, Hide=>0};

       Try to link some C-code making up the body of a function
       with a given set of library specifiers

       return 1 if successful, 0 otherwise

          trylink $infomsg, $include, $progbody, $libs [,{OPTIONS}];

       Takes 4 + 1 optional argument.

       o    an informational message to print (can be empty)

       o    any commands to be included at the top of the gener-
            ated C program (typically something like "#include
            "mylib.h"")

       o    the body of the program (in function main)

       o    library flags to use for linking. Preprocessing by
            MakeMaker should be performed as needed (see options
            and example).

       OPTIONS
            2
            MakeMaker
                Preprocess library in the way MakeMaker does
                things. This is advisable to ensure that your
                code will actually work after the link specs have
                been processed by MakeMaker.

            Hide
                Controls of linking output etc is hidden from the
                user or not.  On by default.
