See the - GNU General Public License for more details. +Perl is a general-purpose programming language originally developed for +text manipulation and now used for a wide range of tasks including +system administration, web development, network programming, GUI +development, and more. - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. +The language is intended to be practical (easy to use, efficient, +complete) rather than beautiful (tiny, elegant, minimal). Its major +features are that it's easy to use, supports both procedural and +object-oriented (OO) programming, has powerful built-in support for text +processing, and has one of the world's most impressive collections of +third-party modules. --------------------------------------------------------------------------- +For an introduction to the language's features, see pod/perlintro.pod. -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. -Perl will probably not run on machines with a small address space. -Please read all the directions below before you proceed any further, and -then follow them carefully. +INSTALLATION +============ -After you have unpacked your kit, you should have all the files listed -in MANIFEST. +If you're using a relatively modern operating system and want to +install this version of Perl locally, run the following commands: -Installation + ./Configure -des -Dprefix=$HOME/localperl + make test + make install -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. +This will configure and compile perl for your platform, run the regression +tests, and install perl in a subdirectory "localperl" of your home directory. - 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 run into any trouble whatsoever or you need to install a customized +version of Perl, you should read the detailed instructions in the "INSTALL" +file that came with this distribution. Additionally, there are a number of +"README" files with hints and tips about building and using Perl on a wide +variety of platforms, some more common than others. - (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.) +Once you have Perl installed, a wealth of documentation is available to you +through the 'perldoc' tool. To get started, run this command: -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. + perldoc perl - If you have any additional changes to make to the C definitions, they - can be done in the Makefile, or in config.h. Bear in mind that they will - get undone next time you run Configure. -3) make depend +IF YOU RUN INTO TROUBLE +======================= - This will look for all the includes and modify Makefile accordingly. - Configure will offer to do this for you. +Perl is a large and complex system that's used for everything from +knitting to rocket science. If you run into trouble, it's quite +likely that someone else has already solved the problem you're +facing. Once you've exhausted the documentation, please report bugs to us +using the 'perlbug' tool. For more information about perlbug, either type +'perldoc perlbug' or just 'perlbug' on a line by itself. -4) make +While it was current when we made it available, Perl is constantly evolving +and there may be a more recent version that fixes bugs you've run into or +adds new features that you might find useful. - 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. It's okay to insert rules for specific files into - Makefile.SH, since a default rule only take effect in the - absence of a specific rule. - - The 3b2 needs to turn off -O. - AIX/RT may need a -a switch and -DCRIPPLED_CC. - SUNOS 4.0.[12] needs #define fputs(str,fp) fprintf(fp,"%s",str) in perl.h - SGI machines may need -Ddouble="long float". - Ultrix (2.3) may need to hand assemble teval.s with a -J switch. - Ultrix on MIPS machines may need -DLANGUAGE_C. - SCO Xenix may need -m25000 for yacc. - Xenix 386 needs -Sm10000 for yacc. - 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. - Machines with half-implemented dbm routines will need to #undef ODBM & NDBM. - 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. - -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@jpl-devvax.jpl.nasa.gov (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. - - 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.
