Mass Deface
and C aren't provided
because the concept does not exist within Plan 9. Others,
such as some of the socket-related functions, simply
haven't been written yet. Many in the latter category
may be supported in the future.
The functions not currently implemented include:
chown, chroot, dbmclose, dbmopen, getsockopt,
setsockopt, recvmsg, sendmsg, getnetbyname,
getnetbyaddr, getnetent, getprotoent, getservent,
sethostent, setnetent, setprotoent, setservent,
endservent, endnetent, endprotoent, umask
There may be several other functions that have undefined
behavior so this list shouldn't be considered complete.
=head2 Signals in Plan 9 Perl
For compatibility with perl scripts written for the Unix
environment, Plan 9 Perl uses the POSIX signal emulation
provided in Plan 9's ANSI POSIX Environment (APE). Signal stacking
isn't supported. The signals provided are:
SIGHUP, SIGINT, SIGQUIT, SIGILL, SIGABRT,
SIGFPE, SIGKILL, SIGSEGV, SIGPIPE, SIGPIPE, SIGALRM,
SIGTERM, SIGUSR1, SIGUSR2, SIGCHLD, SIGCONT,
SIGSTOP, SIGTSTP, SIGTTIN, SIGTTOU
=head1 COMPILING AND INSTALLING PERL ON PLAN 9
WELCOME to Plan 9 Perl, brave soul!
This is a preliminary alpha version of Plan 9 Perl. Still to be
implemented are MakeMaker and DynaLoader. Many perl commands are
missing or currently behave in an inscrutable manner. These gaps will,
with perseverance and a modicum of luck, be remedied in the near
future.To install this software:
1. Create the source directories and libraries for perl by running the
plan9/setup.rc command (i.e., located in the plan9 subdirectory).
Note: the setup routine assumes that you haven't dearchived these
files into /sys/src/cmd/perl. After running setup.rc you may delete
the copy of the source you originally detarred, as source code has now
been installed in /sys/src/cmd/perl. If you plan on installing perl
binaries for all architectures, run "setup.rc -a".
2. After making sure that you have adequate privileges to build system
software, from /sys/src/cmd/perl/5.00301 (adjust version
appropriately) run:
mk install
If you wish to install perl versions for all architectures (68020,
mips, sparc and 386) run:
mk installall
3. Wait. The build process will take a *long* time because perl
bootstraps itself. A 75MHz Pentium, 16MB RAM machine takes roughly 30
minutes to build the distribution from scratch.
=head2 Installing Perl Documentation on Plan 9
This perl distribution comes with a tremendous amount of
documentation. To add these to the built-in manuals that come with
Plan 9, from /sys/src/cmd/perl/5.00301 (adjust version appropriately)
run:
mk man
To begin your reading, start with:
man perl
This is a good introduction and will direct you towards other man
pages that may interest you.
(Note: "mk man" may produce some extraneous noise. Fear not.)
