-Perl is a language that combines some of the features of C, sed, awk and shell.
-See the manual page for more hype. There's also a Nutshell Handbook published
-by O'Reilly & Assoc. Their U.S. number is 1-800-338-6887 (dev-nuts) and
-their international number is 1-707-829-0515. E-mail to nuts@ora.com.

-Perl will probably not run on machines with a small address space.
+Perl is a language that combines some of the features of C, sed, awk
+and shell. See the manual page for more hype. There are also many Perl
+books available, covering a wide variety of topics, from various publishers.
+See pod/perlbook.pod for more information.
Please read all the directions below before you proceed any further, and
then follow them carefully.
Installation
-1) Run Configure. This will figure out various things about your system.
- Some things Configure will figure out for itself, other things it will
- ask you about. It will then proceed to make config.h, config.sh, and
- Makefile. If you're a hotshot, run Configure -d to take all the
- defaults and then edit config.sh to patch up any flaws.
-
- You might possibly have to trim # comments from the front of Configure
- if your sh doesn't handle them, but all other # comments will be taken
- care of.
-
- (If you don't have sh, you'll have to copy the sample file config.H to
- config.h and edit the config.h to reflect your system's peculiarities.)
-
-2) Glance through config.h to make sure system dependencies are correct.
- Most of them should have been taken care of by running the Configure script.
-
- If you have any additional changes to make to the C definitions, they
- can be done in cflags.SH. For instance, to turn off the optimizer
- on eval.c, find the line in the switch structure for eval.c and
- put the command $optimize='-g' before the ;;. You will probably
- want to change the entry for teval.c too. To change the C flags
- for all the files, edit config.sh and change either $ccflags or $optimize.
-
-3) make depend
-
- This will look for all the includes and modify Makefile accordingly.
- Configure will offer to do this for you.
-
-4) make
-
- This will attempt to make perl in the current directory.
-
- If you can't compile successfully, try adding a -DCRIPPLED_CC flag.
- (Just because you get no errors doesn't mean it compiled right!)
- This simplifies some complicated expressions for compilers that
- get indigestion easily. If that has no effect, try turning off
- optimization. If you have missing routines, you probably need to
- add some library or other, or you need to undefine some feature that
- Configure thought was there but is defective or incomplete.
-
- Some compilers will not compile or optimize the larger files without
- some extra switches to use larger jump offsets or allocate larger
- internal tables. You can customize the switches for each file in
- cflags.SH. It's okay to insert rules for specific files into
- Makefile.SH, since a default rule only takes effect in the
- absence of a specific rule.
-
- Most of the following hints are now done automatically by Configure.
-
- The 3b2 needs to turn off -O.
- Compilers with limited switch tables may have to define -DSMALLSWITCHES
- Domain/OS 10.3 (at least) native C 6.7 may need -opt 2 for eval.c
- AIX/RT may need a -a switch and -DCRIPPLED_CC.
- AIX RS/6000 needs to use system malloc and avoid -O on eval.c and toke.c.
- AIX RS/6000 needs -D_NO_PROTO.
- SUNOS 4.0.[12] needs -DFPUTS_BOTCH.
- SUNOS 3.[45] should use the system malloc.
- SGI machines may need -Ddouble="long float" and -O1.
- Vax-based systems may need to hand assemble teval.s with a -J switch.
- Ultrix on MIPS machines may need -DLANGUAGE_C.
- Ultrix 4.0 on MIPS machines may need -Olimit 2900 or so.
- Ultrix 3.[01] on MIPS needs to undefine WAITPID--the system call is busted.
- MIPS machines need /bin before /bsd43/bin in PATH.
- MIPS machines may need to undef d_volatile.
- MIPS machines may need to turn off -O on cmd.c, perl.c and tperl.c.
- Some MIPS machines may need to undefine CASTNEGFLOAT.
- Xenix 386 needs -Sm11000 for yacc, and may need -UM_I86.
- SCO Xenix may need -m25000 for yacc. See also README.xenix.
- Genix needs to use libc rather than libc_s, or #undef VARARGS.
- NCR Tower 32 (OS 2.01.01) may need -W2,-Sl,2000 and #undef MKDIR.
- A/UX may appears to work with -O -B/usr/lib/big/ optimizer flags.
- A/UX needs -lposix to find rewinddir.
- A/UX may need -ZP -DPOSIX, and -g if big cc is used.
- FPS machines may need -J and -DBADSWITCH.
- UTS may need one or more of -DCRIPPLED_CC, -K or -g, and undef LSTAT.
- dynix may need to undefine CASTNEGFLOAT (d_castneg='undef' in config.sh).
- Dnix (not dynix) may need to remove -O.
- IRIX 3.3 may need to undefine VFORK.
- HP/UX may need to pull cerror.o and syscall.o out of libc.a and link
- them in explicitly.
- If you get syntax errors on '(', try -DCRIPPLED_CC or -DBADSWITCH or both.
- Machines with half-implemented dbm routines will need to #undef ODBM & NDBM.
- If you have GDBM available and want it instead of NDBM, say -DHAS_GDBM.
- C's that don't try to restore registers on longjmp() may need -DJMPCLOBBER.
- (Try this if you get random glitches.)
-
-5) make test
-
- This will run the regression tests on the perl you just made.
- If it doesn't say "All tests successful" then something went wrong.
- See the README in the t subdirectory. Note that you can't run it
- in background if this disables opening of /dev/tty. If "make test"
- bombs out, just cd to the t directory and run TEST by hand to see if
- it makes any difference. If individual tests bomb, you can run
- them by hand, e.g., ./perl op/groups.t
-
-6) make install
-
- This will put perl into a public directory (such as /usr/local/bin).
- It will also try to put the man pages in a reasonable place. It will not
- nroff the man page, however. You may need to be root to do this. If
- you are not root, you must own the directories in question and you should
- ignore any messages about chown not working.
-
-7) Read the manual entry before running perl.
-
-8) IMPORTANT! Help save the world! Communicate any problems and suggested
- patches to me, lwall@netlabs.com (Larry Wall), so we can
- keep the world in sync. If you have a problem, there's someone else
- out there who either has had or will have the same problem.
-
- If possible, send in patches such that the patch program will apply them.
- Context diffs are the best, then normal diffs. Don't send ed scripts--
- I've probably changed my copy since the version you have. It's also
- helpful if you send the output of "uname -a".
-
- Watch for perl patches in comp.lang.perl. Patches will generally be
- in a form usable by the patch program. If you are just now bringing up
- perl and aren't sure how many patches there are, write to me and I'll
- send any you don't have. Your current patch level is shown in patchlevel.h.
+1) Detailed instructions are in the file "INSTALL", which you should
+read if you are either installing on a system resembling Unix
+or porting perl to another platform. For non-Unix platforms, see the
+corresponding README.
+
+2) Read the manual entries before running perl.
+
+3) IMPORTANT! Help save the world! Communicate any problems and suggested
+patches to perlbug@perl.com so we can keep the world in sync.
+If you have a problem, there's someone else out there who either has had
+or will have the same problem. It's usually helpful if you send the
+output of the "myconfig" script in the main perl directory.
+
+If you've succeeded in compiling perl, the perlbug script in the "utils"
+subdirectory can be used to help mail in a bug report.
+
+If possible, send in patches such that the patch program will apply them.
+Context diffs are the best, then normal diffs. Don't send ed scripts--
+I've probably changed my copy since the version you have.
+
