But that doesn't work with the AUTOWRAP script that I have ... and I'm not able to come to an understanding of why that is so ... given my (now) current state of insobriety. Perhaps all will become clear to me tomorrow. In the meantime, here's 'autowrap.pl':

use warnings;

use Inline C => Config =>
    BUILD_NOISY => 1,
    TYPEMAPS => 'simple_typemap.txt',
    AUTO_INCLUDE => '#include "D:/C/simple.h"',
    CLEAN_AFTER_BUILD => 0,
    ENABLE => AUTOWRAP,
    LIBS => '-LD:/C -lsimple';

use Inline C => q{simple_double simple(simple_double); };

print simple(1.032);

and here's what happens when I run 'perl autowrap.pl' (using your amendments to C.pm):

Execution of Makefile.PL aborted due to compilation errors.

A problem was encountered while attempting to compile and install your

C code. The command that failed was:
  D:\perl58_M\5.8.8\bin\perl.exe Makefile.PL

The build directory was:
D:\pscrpt\inline\special\_Inline\build\autowrap_pl_e826

To debug the problem, cd to the build directory, and inspect the outpu
+t files.

'simple.h' looks like:

#define simple_double double
simple_double simple(simple_double d);
[download]

and 'simple_typemap.txt' looks like:

simple_double T_S_DOUBLE

INPUT
T_S_DOUBLE
          $var = (simple_double)SvNV($arg)

OUTPUT
T_S_DOUBLE
          sv_setnv($arg, (simple_double)$var);

Perhaps it's just a simple syntax error in the code you posted ... but I couldn't spot it. It's creating a Makefile.PL that looks like this:

use ExtUtils::MakeMaker;
my %options = (       
'TYPEMAPS'
[
  'D:\\perl58_M\\5.8.8\\lib\\ExtUtils\\typemap',
  'D:\\pscrpt\\inline\\special\\simple_typemap.txt'
]
'NAME'
'autowrap_pl_e826'
'INC'
'-ID:/pscrpt/inline/special'
'LIBS'
[
  '-LD:/C -lsimple'
]
'VERSION'
'0.00'
);
WriteMakefile(%options);

# Remove the Makefile dependency. Causes problems on a few systems.
sub MY::makefile { '' }

Gotta go to bed :-)
