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. If the test scripts and programs
- run ok, the defaults will usually be right. It will then proceed to
- make config.h, config.sh, and Makefile. You may have to explicitly
- say sh Configure to ensure that Configure is run under sh.
- If you're a hotshot, run Configure -d to take all the defaults and
- then edit config.sh to patch up any flaws and run Configure -S.
-
- Configure supports a number of useful options. Run Configure -h
- to get a listing. To compile with gcc, for example, you can run
- Configure -Dcc=gcc, or answer 'gcc' at the cc prompt. This is the
- preferred way to invoke an alternate compiler, since the hints
- files can then set appropriate defaults.
-
- If you change compilers or make other significant changes, you should
- probably _not_ re-use your old config.sh. Simply remove it or
- rename it, e.g. mv config.sh config.sh.old.
-
- By default, perl will be installed in /usr/local/{bin, lib, man}.
- You can specify a different prefix for the default installation
- directory, when Configure prompts you or by using something like
- Configure -Dprefix=/whatever.
-
- You can also supply a file config.over to over-ride Configure's
- guesses. It will get loaded up at the very end, just before
- config.sh is created.
-
- 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 toke.c, find the line in the switch structure for toke.c and
- put the command optimize='-g' before the ;;. 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.
-
- Many of the following hints are now done automatically by Configure.
- Some of the hints here were for Perl 4, and are probably obsolete.
- They're left here for the moment just to give you some ideas for
- what to try if you're having trouble.
-
- AIX/RT may need a -a switch and -DCRIPPLED_CC.
- Ultrix 3.[01] on MIPS needs to undefine WAITPID--the system call is busted.
- MIPS machines may need to undef d_volatile.
- MIPS machines may need to turn off -O on some files.
- Some MIPS machines may need to undefine CASTNEGFLOAT.
- Genix may need 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 appear to work with -O -B/usr/lib/big/ optimizer flags.
- A/UX may need -lposix to find rewinddir.
- A/UX may need -ZP -DPOSIX, and -g if big cc is used.
- UTS may need one or more of -DCRIPPLED_CC, -K or -g, and undef LSTAT.
- If you get syntax errors on '(', try -DCRIPPLED_CC.
- Machines with half-implemented dbm routines will need to #undef I_ODBM
- SCO prior to 3.2.4 may be missing dbmclose(). An upgrade to 3.2.4
- that includes libdbm.nfs (which includes dbmclose()) may be available.
- If you get duplicates upon linking for malloc et al, say -DHIDEMYMALLOC.
- If you get duplicate function definitions (a perl function has the
- same name as another function on your system) try -DEMBED.
- If you get varags problems with gcc, be sure that gcc is installed
- correctly. When using gcc, you should probably have i_stdarg='define'
- and i_varags='undef' in config.sh.
- If you wish to use dynamic loading on SunOS or Solaris, and you
- have GNU as and GNU ld installed, you may need to add -B/bin/ to
- your $ccflags and $ldflags so that the system's versions of as
- and ld are used.
-
-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.
-
- make install will also install the following:
- perl,
- perl5.nnn where nnn is the current release number. This
- will be a link to perl.
- suidperl,
- sperl5.nnn If you requested setuid emulation.
- a2p awk-to-perl translator
- cppstdin This is used by perl -P, if your cc -E can't
- read from stdin.
- c2ph, pstruct Scripts for handling C structures in header files.
- s2p sed-to-perl translator
- find2perl find-to-perl translator
- h2xs Converts C .h header files to Perl extensions.
- pod2html, Converters from perl's pod documentation format
- pod2latex, and to other useful formats.
- pod2man
-
- library files in $privlib and $archlib specified to
- Configure, usually under /usr/local/lib/perl5/.
- man pages in the location specified to Configure, usually
- something like /usr/local/man/man1.
-
- Perl's *.h header files and the libperl.a library are also
- installed under $archlib so that you may later build new
- extensions even if the Perl source is no longer available.
-
- make install may also offer to install perl in a "standard" location.
-
- Most of the documentation in the pod/ directory is also available
- in HTML format. Type
- cd pod; make html; cd ..
- to generate the html versions.
-
-7) Read the manual entries 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.
+
+The latest versions of perl are always available on the various CPAN
+(Comprehensive Perl Archive Network) sites around the world.

Just a personal note: I want you to know that I create nice things like this
