It is written in the POD format (see pod/perlpod.pod) which is +specially designed to be readable as is. + +=head1 NAME + +README.machten - Perl version 5 on Power MachTen systems + +=head1 DESCRIPTION + +This document describes how to build Perl 5 on Power MachTen systems, +and discusses a few wrinkles in the implementation. + +=head2 Compiling Perl 5 on MachTen + +To compile perl under MachTen 4.1.4 (and probably earlier versions): + + ./Configure -de + make + make test + make install + +This builds and installs a statically-linked perl; MachTen's dynamic +linking facilities are not adequate to support Perl's use of +dynamically linked libraries. (See F<hints/machten.sh> for more +information.) + +You should have at least 32 megabytes of free memory on your +system before running the C<make> command. + +For much more information on building perl -- for example, on how to +change the default installation directory -- see F<INSTALL>. + +=head2 Failures during C<make test> + +=over 4 + +=item op/lexassign.t + +This test may fail when first run after building perl. It does not +fail subsequently. The cause is unknown. + +=item op/taint.t + +This test emits various complaints such as "Operation not permitted", +but passes. The cause is an incomplete implementation of System V +inter-process communication in MachTen 4.1.4. In versions prior to +4.1.4, the implementation was so incomplete that the hints file +disables its incorporation into perl; in 4.1.4, the facilities are +useable with care. + +=item pragma/warnings.t + +Test 257 fails due to a failure to warn about attempts to read from a +filehandle which is a duplicate of stdout when stdout is attached to a +pipe. The output of the test contains a block comment which discusses +a different failure, not applicable to MachTen. + +The root of the problem is that Machten does not assign a file type to +either end of a pipe (see L<stat>), resulting, among other things +in Perl's C<-p> test failing on file descriptors belonging to pipes. +As a result, perl becomes confused, and the test for reading from a +write-only file fails. I am reluctant to patch perl to get around +this, as it's clearly an OS bug (about which Tenon has been informed), +and limited in its effect on practical Perl programs. + +=back + +=head2 Using external modules + +If warnings are enabled with Perl's C<-w> command-line flag, you are +likely to see warnings when using external modules containing XS +(compiled) code: + + Subroutine DynaLoader::dl_error redefined at /usr/local/lib/perl5/5.6.0/powerpc-machten/DynaLoader.pm line 93. + +This is a harmless consequence of the static linking used for MachTen +perl. You can suppress the warnings by using the more modern +C<-Mwarnings> instead of the traditional C<-w>. (See L<perllexwarn>.) + +=head2 Building external modules + +To add an external module to perl, build in the normal way, which +is documented in L<ExtUtils::MakeMaker>, or which can be driven +automatically by the CPAN module (see L<CPAN>), which is part of the +standard distribution. If wou want to install a +module contains XS code (C or C++ source which compiles to object code +for linking with perl), you will have to replace your perl binary with +a new version containing the new statically-linked object module. The +build process tells you how to do this. + +There is a gotcha, however, which users usually encounter immediately +they respond to CPAN's invitation to C<install Bundle::CPAN>. When +installing a I<bundle> -- a group of modules which together achieve +some particular purpose, the installation process for later modules in +the bundle tends to assume that earlier modules have been fully +installed and are available for use. This is not true on a +statically-linked system for earlier modules which contain XS code. +As a result the installation of the bundle fails. The work-around is +not to install the bundle as a one-shot operation, but instead to see +what modules it contains, and install these one-at-a-time by hand in +the order given. + +=head1 AUTHOR + +Dominic Dunlop <domo@computer.org> + +=head1 DATE + +Version 1.0 2000-03-22 diff --git a/pod/perl.pod b/pod/perl.pod index 221f7f4c23..59ca0e0368 100644 --- a/pod/perl.pod +++ b/pod/perl.pod @@ -85,6 +85,7 @@ sections: perlcygwin Perl notes for Cygwin perldos Perl notes for DOS perlhpux Perl notes for HP-UX + perlmachten Perl notes for Power MachTen perlos2 Perl notes for OS/2 perlos390 Perl notes for OS/390 perlvms Perl notes for VMS diff --git a/win32/Makefile b/win32/Makefile index 12adc38082..f1aea7564b 100644 --- a/win32/Makefile +++ b/win32/Makefile @@ -963,6 +963,13 @@ utils: $(PERLEXE) $(X2P) cd ..\utils $(MAKE) PERL=$(MINIPERL) cd ..\pod + copy ..\README.amiga .\perlamiga.pod + copy ..\README.cygwin .\perlcygwin.pod + copy ..\README.dos .\perldos.pod + copy ..\README.hpux .\perlhpux.pod + copy ..\README.machten .\perlmachten.pod + copy ..\README.os2 .\perlos2.pod + copy ..\vms\perlvms.pod .\perlvms.pod copy ..\README.win32 .\perlwin32.pod $(MAKE) -f ..\win32\pod.mak converters cd ..\win32 diff --git a/win32/makefile.mk b/win32/makefile.mk index 7dd2902f86..fdaeba39e5 100644 --- a/win32/makefile.mk +++ b/win32/makefile.mk @@ -1182,7 +1182,14 @@ doc: $(PERLEXE) utils: $(PERLEXE) $(X2P) cd ..\utils && $(MAKE) PERL=$(MINIPERL) - copy ..\README.win32 ..\pod\perlwin32.pod + copy ..\README.amiga ..\pod\perlamiga.pod + copy ..\README.cygwin ..\pod\perlcygwin.pod + copy ..\README.dos ..\pod\perldos.pod + copy ..\README.hpux ..\pod\perlhpux.pod + copy ..\README.machten ..\pod\perlmachten.pod + copy ..\README.os2 ..\pod\perlos2.pod + copy ..\README.os2 ..\pod\perlos2.pod + copy ..\vms\perlvms.pod ..\pod\perlvms.pod cd ..\pod && $(MAKE) -f ..\win32\pod.mak converters $(PERLEXE) $(PL2BAT) $(UTILS) |
