README.machten - Perl version 5 on Power MachTen systems
This document describes how to build Perl 5 on Power MachTen systems, and discusses a few wrinkles in the implementation.
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 hints/machten.sh for more information.)
You should have at least 32 megabytes of free memory on your
system before running the
For much more information on building perl -- for example, on how to change the default installation directory -- see INSTALL.
make teston MachTen
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
-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.
To add an external module to perl, build in the normal way, which is documented in ExtUtils::MakeMaker, or which can be driven automatically 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.
