2 /* ppport.h -- Perl/Pollution/Portability Version 2.011
4 * Automatically Created by Devel::PPPort on Thu Apr 22 16:13:04 2004
6 * 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.
