* Automatically Created by Devel::PPPort on Sun Jul 4 09:11:52 2004

* Do NOT edit this file directly! -- Edit PPPort.pm instead.
8
* Version 2.x, Copyright (C) 2001, Paul Marquess.
9
* Version 1.x, Copyright (C) 1999, Kenneth Albanowski.
10
* This code may be used and distributed under the same license as any
13
* This version of ppport.h is designed to support operation with Perl
14
* installations back to 5.004, and has been tested up to 5.8.1.
16
* If this version of ppport.h is failing during the compilation of this
17
* module, please check if a newer version of Devel::PPPort is available
18
* on CPAN before sending a bug report.
20
* If you are using the latest version of Devel::PPPort and it is failing
21
* during compilation of this module, please send a report to perlbug@perl.com
23
* Include all following information:
25
* 1. The complete output from running "perl -V"
29
* 3. The name & version of the module you were trying to build.
31
* 4. A full log of the build that failed.
33
* 5. Any other information that you think could be relevant.
36
* For the latest version of this code, please retreive the Devel::PPPort
42
* In order for a Perl extension module to be as portable as possible
43
* across differing versions of Perl itself, certain steps need to be taken.
44
* Including this header is the first major one, then using dTHR is all the
45
* appropriate places and using a PL_ prefix to refer to global Perl
46
* variables is the second.
51
/* If you use one of a few functions that were not present in earlier
52
* versions of Perl, please add a define before the inclusion of ppport.h
53
* for a static include, or use the GLOBAL request in a single module to
54
* produce a global definition that can be referenced from the other
57
* Function: Static define: Extern define:
58
* newCONSTSUB() NEED_newCONSTSUB NEED_newCONSTSUB_GLOBAL
63
/* To verify whether ppport.h is needed for your module, and whether any
64
* special defines should be used, ppport.h can be run through Perl to check
65
* your source code. Simply say:
67
* perl -x ppport.h *.c *.h *.xs foo/bar*.c [etc]
69
* The result will be a list of patches suggesting changes that should at
70
* least be acceptable, if not necessarily the most efficient solution, or a
71
* fix for all possible problems. It won't catch where dTHR is needed, and
72
* doesn't attempt to account for global macro or function definitions,
73
* nested includes, typemaps, etc.
75
* In order to test for the need of dTHR, please try your module under a
76
* recent version of Perl that has threading compiled-in.
