Perl XS

System: Slackware Linux (version 14.0)
CPUs: Intel(R) Atom(TM) CPU N270 @1.60GHz

I found J. Keiser's article on Perl and C++ in an archive, and created
a Github repository, including also D. Roehrich's perlobject.map file.

Starting with Perl 5.16, you can embed typemaps into your XS code
instead of or in addition to typemaps in a separate file.

The -C++ flag has been a no-op for many versions of perl, at least
as far back as perl5.003_07.


sh-4.2$ perl --version | grep version
This is perl 5, version 16, subversion 1 (v5.16.1) built for i486-linux-thread-multi
sh-4.2$ cd /tmp
sh-4.2$ h2xs -A -n MyPackage
Defaulting to backwards compatibility with perl 5.16.1
If you intend this module to be compatible with earlier perl versions, please
specify a minimum perl version with the -b option.

Writing MyPackage/lib/MyPackage.pm
Writing MyPackage/MyPackage.xs
Writing MyPackage/Makefile.PL
Writing MyPackage/README
Writing MyPackage/t/MyPackage.t

Writing MyPackage/MANIFEST
sh-4.2$

Modify MyPackage.xs as follows.

#ifdef __cplusplus
extern "C" {
#endif

#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#ifdef __cplusplus
}
#endif


#include "ppport.h"


MODULE = MyPackage         PACKAGE = MyPackage

PROTOTYPES: ENABLE

One needs the repository's perlobject.map file and to create a typemap file.

sh-4.2$ cp perlobject.map MyPackage
sh-4.2$ cat << EOF > MyPackage/typemap
> TYPEMAP
> MyClass *         O_OBJECT

Modify Makefile.PL as follows.

use 5.016001;
use ExtUtils::MakeMaker;

my $CC = 'g++';
my $LD = '$(CC)';


# See lib/ExtUtils/MakeMaker.pm for details of how to influence
# the contents of the Makefile that is written.
WriteMakefile(

      (ABSTRACT_FROM  => 'lib/MyPackage.pm', # retrieve abstract from module
       AUTHOR         => 'Eric Lindblad <eric@slackware.lan>') : ()),

    DEFINE            => '', # e.g., '-DHAVE_SOMETHING'
    CC                    => $CC,
    LD                     => $LD,

    INC               => '-I.', # e.g., '-I. -I/usr/include/other'
             # Un-comment this if you add C files to link with later:
    # OBJECT            => '$(O_FILES)', # link all the C files too
    TYPEMAPS        => ['perlobject.map'],
);

Start emacs and type ‘M-x list-packages’, to initialise the package manager.

Next type ‘M-x package-install RET ebdb’ and then confirm when prompted.

Looks like 'ebdb' patching is needed for emacs-25.3.

ebdb-migrate.el fails to byte compile

Compiler-macro error for cl--block-wrapper: (wrong-number-of-arguments (3 . 5) 6) [3 times]

This was just a test today of the package manager library for ELPA.
