NAME
README.machten - Perl version 5 on Power MachTen systems
DESCRIPTION
This document describes how to build Perl 5 on Power MachTen systems, and discusses a few wrinkles in the implementation.
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 dynami-
cally linked libraries. (See hints/machten.sh for more information.)
You should have at least 32 megabytes of free memory on your system before running the "make" command.
For much more information on building perl -- for example, on how to change the default installation directory -- see INSTALL.
Failures during "make test" on MachTen
op/lexassign.t
This test may fail when first run after building perl. It does not fail subsequently. The cause is unknown.
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 stat), resulting, among other things
in Perl's "-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.
Building external modules on MachTen
To add an external module to perl, build in the normal way, which is documented in ExtUtils::MakeMaker, or which can be driven automati-
cally by the CPAN module (see CPAN), which is part of the standard distribution. If you want to install a module which 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 "install Bundle::CPAN". When
installing a 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.
