       PDL::Core::Dev - PDL development module


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


          use PDL::Core::Dev;


       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" element of perl's %Config array.

          my $retval = isbigendian();

       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, $cflags,
               {MakeMaker=>1, Hide=>0, Clean=>1};

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

       return 1 if successful, 0 otherwise

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

       Takes 4 + 2 optional arguments.

       ·    an informational message to print (can be empty)

       ·    any commands to be included at the top of the generated C program (typically
            something like "#include "mylib.h"")

       ·    the body of the program (in function main)

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

       ·    compilation flags. For example, something like "-I/usr/local/lib".  Optional
            argument. Empty if omitted.

       ·    OPTIONS

                Preprocess library strings 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.

                Controls if linking output etc is hidden from the user or not.  On by default
                except within the build of the PDL distribution where the config value set in
                perldl.conf prevails.

                Remove temporary files. Enabled by default. You might want to switch it off
                during debugging.
