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; if ($^O =~ /win32/i) { warn "Win32 systems not yet supported. Will not build PDL::IO::Browser"; write_dummy_make(unsupported('PDL::XXX','win32')); return; }
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, {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.
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")
#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).
OPTIONS
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.
Controls of linking output etc is hidden from the user or not. On by default.
