7 README.machten - Perl version 5 on Power MachTen systems
11 This document describes how to build Perl 5 on Power MachTen systems,
12 and discusses a few wrinkles in the implementation.
14 =head2 Compiling Perl 5 on MachTen
16 To compile perl under MachTen 4.1.4 (and probably earlier versions):
23 This builds and installs a statically-linked perl; MachTen's dynamic
24 linking facilities are not adequate to support Perl's use of
25 dynamically linked libraries. (See F<hints/machten.sh> for more
28 You should have at least 32 megabytes of free memory on your
29 system before running the C<make> command.
31 For much more information on building perl -- for example, on how to
32 change the default installation directory -- see F<INSTALL>.
34 =head2 Failures during C<make test> on MachTen
40 This test may fail when first run after building perl. It does not
41 fail subsequently. The cause is unknown.
43 =item pragma/warnings.t
45 Test 257 fails due to a failure to warn about attempts to read from a
46 filehandle which is a duplicate of stdout when stdout is attached to a
47 pipe. The output of the test contains a block comment which discusses
48 a different failure, not applicable to MachTen.
50 The root of the problem is that Machten does not assign a file type to
51 either end of a pipe (see L<stat>), resulting, among other things
52 in Perl's C<-p> test failing on file descriptors belonging to pipes.
53 As a result, perl becomes confused, and the test for reading from a
54 write-only file fails. I am reluctant to patch perl to get around
55 this, as it's clearly an OS bug (about which Tenon has been informed),
56 and limited in its effect on practical Perl programs.
60 =head2 Building external modules on MachTen
62 To add an external module to perl, build in the normal way, which
63 is documented in L<ExtUtils::MakeMaker>, or which can be driven
64 automatically by the CPAN module (see L<CPAN>), which is part of the
65 standard distribution. If you want to install a module which
66 contains XS code (C or C++ source which compiles to object code
67 for linking with perl), you will have to replace your perl binary with
68 a new version containing the new statically-linked object module. The
69 build process tells you how to do this.
71 There is a gotcha, however, which users usually encounter immediately
72 they respond to CPAN's invitation to C<install Bundle::CPAN>. When
73 installing a I<bundle> -- a group of modules which together achieve
74 some particular purpose, the installation process for later modules in
75 the bundle tends to assume that earlier modules have been fully
76 installed and are available for use. This is not true on a
77 statically-linked system for earlier modules which contain XS code.
78 As a result the installation of the bundle fails. The work-around is
79 not to install the bundle as a one-shot operation, but instead to see
80 what modules it contains, and install these one-at-a-time by hand in
