Whenever anyone creates a chunk of Perl code that they think will be useful to the world, they register as a Perl developer at http://www.cpan.org/modules/04pause.html so that they can then upload their code to the \s-1CPAN\s0. The \s-1CPAN\s0 is the Comprehensive Perl Archive Network and can be accessed at http://www.cpan.org/ , and searched at http://search.cpan.org/ . .PP This documentation is for people who want to download \s-1CPAN\s0 modules and install them on their own computer. .SS "\s-1PREAMBLE\s0" .IX Subsection "PREAMBLE" First, are you sure that the module isn't already on your system? Try \&\f(CW\*(C`perl \-MFoo \-e 1\*(C'\fR. (Replace \*(L"Foo\*(R" with the name of the module; for instance, \f(CW\*(C`perl \-MCGI::Carp \-e 1\*(C'\fR. .PP If you don't see an error message, you have the module. (If you do see an error message, it's still possible you have the module, but that it's not in your path, which you can display with \f(CW\*(C`perl \-e "print qq(@INC)"\*(C'\fR.) For the remainder of this document, we'll assume that you really honestly truly lack an installed module, but have found it on the \s-1CPAN\s0. .PP So now you have a file ending in .tar.gz (or, less often, .zip). You know there's a tasty module inside. There are four steps you must now take: .IP "\fB\s-1DECOMPRESS\s0\fR the file" 5 .IX Item "DECOMPRESS the file" .PD 0 .IP "\fB\s-1UNPACK\s0\fR the file into a directory" 5 .IX Item "UNPACK the file into a directory" .IP "\fB\s-1BUILD\s0\fR the module (sometimes unnecessary)" 5 .IX Item "BUILD the module (sometimes unnecessary)" .IP "\fB\s-1INSTALL\s0\fR the module." 5 .IX Item "INSTALL the module." .PD .PP Here's how to perform each step for each operating system. This is <not> a substitute for reading the \s-1README\s0 and \s-1INSTALL\s0 files that might have come with your module! .PP Also note that these instructions are tailored for installing the module into your system's repository of Perl modules, but you can install modules into any directory you wish. For instance, where I say \f(CW\*(C`perl Makefile.PL\*(C'\fR, you can substitute \f(CW\*(C`perl Makefile.PL PREFIX=/my/perl_directory\*(C'\fR to install the modules into \&\f(CW\*(C`/my/perl_directory\*(C'\fR. Then you can use the modules from your Perl programs with \f(CW\*(C`use lib "/my/perl_directory/lib/site_perl";\*(C'\fR or sometimes just \f(CW\*(C`use "/my/perl_directory";\*(C'\fR. If you're on a system that requires superuser/root access to install modules into the directories you see when you type \f(CW\*(C`perl \-e "print qq(@INC)"\*(C'\fR, you'll want to install them into a local directory (such as your home directory) and use this approach. .IP "\(bu" 4 \&\fBIf you're on a Unix or Unix-like system,\fR .Sp You can use Andreas Koenig's \s-1CPAN\s0 module ( http://www.cpan.org/modules/by\-module/CPAN ) to automate the following steps, from \s-1DECOMPRESS\s0 through \s-1INSTALL\s0. .Sp A. \s-1DECOMPRESS\s0 .Sp Decompress the file with \f(CW\*(C`gzip \-d yourmodule.tar.gz\*(C'\fR .Sp You can get gzip from ftp://prep.ai.mit.edu/pub/gnu/ .Sp Or, you can combine this step with the next to save disk space: .Sp .Vb 1 \& gzip \-dc yourmodule.tar.gz | tar \-xof \- .Ve .Sp B. \s-1UNPACK\s0 .Sp Unpack the result with \f(CW\*(C`tar \-xof yourmodule.tar\*(C'\fR .Sp C. \s-1BUILD\s0 .Sp Go into the newly-created directory and type: .Sp .Vb 2 \& perl Makefile.PL \& make test .Ve .Sp or .Sp .Vb 1 \& perl Makefile.PL PREFIX=/my/perl_directory .Ve .Sp to install it locally. (Remember that if you do this, you'll have to put \f(CW\*(C`use lib "/my/perl_directory";\*(C'\fR near the top of the program that is to use this module. .Sp D. \s-1INSTALL\s0 .Sp While still in that directory, type: .Sp .Vb 1 \& make install .Ve .Sp Make sure you have the appropriate permissions to install the module in your Perl 5 library directory. Often, you'll need to be root. .Sp That's all you need to do on Unix systems with dynamic linking. Most Unix systems have dynamic linking. If yours doesn't, or if for another reason you have a statically-linked perl, \fBand\fR the module requires compilation, you'll need to build a new Perl binary that includes the module. Again, you'll probably need to be root. .IP "\(bu" 4 \&\fBIf you're running ActivePerl (Win95/98/2K/NT/XP, Linux, Solaris)\fR .Sp First, type \f(CW\*(C`ppm\*(C'\fR from a shell and see whether ActiveState's \s-1PPM\s0 repository has your module. If so, you can install it with \f(CW\*(C`ppm\*(C'\fR and you won't have to bother with any of the other steps here. You might be able to use the \s-1CPAN\s0 instructions from the \*(L"Unix or Linux\*(R" section above as well; give it a try. Otherwise, you'll have to follow the steps below. .Sp .Vb 1 \& A. DECOMPRESS .Ve .Sp You can use the shareware Winzip ( http://www.winzip.com ) to decompress and unpack modules. .Sp .Vb 1 \& B. UNPACK .Ve .Sp If you used WinZip, this was already done for you. .Sp .Vb 1 \& C. BUILD .Ve .Sp You'll need the \f(CW\*(C`nmake\*(C'\fR utility, available at http://download.microsoft.com/download/vc15/Patch/1.52/W95/EN\-US/nmake15.exe or dmake, available on \s-1CPAN\s0. http://search.cpan.org/dist/dmake/ .Sp Does the module require compilation (i.e. does it have files that end in .xs, .c, .h, .y, .cc, .cxx, or .C)? If it does, life is now officially tough for you, because you have to compile the module yourself (no easy feat on Windows). You'll need a compiler such as Visual \*(C+. Alternatively, you can download a pre-built \s-1PPM\s0 package from ActiveState. http://aspn.activestate.com/ASPN/Downloads/ActivePerl/PPM/ .Sp Go into the newly-created directory and type: .Sp .Vb 2 \& perl Makefile.PL \& nmake test \& \& \& D. INSTALL .Ve .Sp While still in that directory, type: .Sp .Vb 1 \& nmake install .Ve .IP "\(bu" 4 \&\fBIf you're using a Macintosh with \*(L"Classic\*(R" MacOS and MacPerl,\fR .Sp A. \s-1DECOMPRESS\s0 .Sp First, make sure you have the latest \fBcpan-mac\fR distribution ( http://www.cpan.org/authors/id/CNANDOR/ ), which has utilities for doing all of the steps. Read the cpan-mac directions carefully and install it. If you choose not to use cpan-mac for some reason, there are alternatives listed here. .Sp After installing cpan-mac, drop the module archive on the \&\fBuntarzipme\fR droplet, which will decompress and unpack for you. .Sp \&\fBOr\fR, you can either use the shareware \fBStuffIt Expander\fR program ( http://my.smithmicro.com/mac/stuffit/ ) or the freeware \fBMacGzip\fR program ( http://persephone.cps.unizar.es/general/gente/spd/gzip/gzip.html ). .Sp B. \s-1UNPACK\s0 .Sp If you're using untarzipme or StuffIt, the archive should be extracted now. \fBOr\fR, you can use the freeware \fBsuntar\fR or \fITar\fR ( http://hyperarchive.lcs.mit.edu/HyperArchive/Archive/cmp/ ). .Sp C. \s-1BUILD\s0 .Sp Check the contents of the distribution. Read the module's documentation, looking for reasons why you might have trouble using it with MacPerl. Look for \&\fI.xs\fR and \fI.c\fR files, which normally denote that the distribution must be compiled, and you cannot install it \*(L"out of the box.\*(R" (See \*(L"\s-1PORTABILITY\s0\*(R".) .Sp D. \s-1INSTALL\s0 .Sp If you are using cpan-mac, just drop the folder on the \&\fBinstallme\fR droplet, and use the module. .Sp \&\fBOr\fR, if you aren't using cpan-mac, do some manual labor. .Sp Make sure the newlines for the modules are in Mac format, not Unix format. If they are not then you might have decompressed them incorrectly. Check your decompression and unpacking utilities settings to make sure they are translating text files properly. .Sp As a last resort, you can use the perl one-liner: .Sp .Vb 1 \& perl \-i.bak \-pe \*(Aqs/(?:\e015)?\e012/\e015/g\*(Aq <filenames> .Ve .Sp on the source files. .Sp Then move the files (probably just the \fI.pm\fR files, though there may be some additional ones, too; check the module documentation) to their final destination: This will most likely be in \f(CW\*(C`$ENV{MACPERL}site_lib:\*(C'\fR (i.e., \&\f(CW\*(C`HD:MacPerl folder:site_lib:\*(C'\fR). You can add new paths to the default \f(CW@INC\fR in the Preferences menu item in the MacPerl application (\f(CW\*(C`$ENV{MACPERL}site_lib:\*(C'\fR is added automagically). Create whatever directory structures are required (i.e., for \f(CW\*(C`Some::Module\*(C'\fR, create \&\f(CW\*(C`$ENV{MACPERL}site_lib:Some:\*(C'\fR and put \&\f(CW\*(C`Module.pm\*(C'\fR in that directory). .Sp Then run the following script (or something like it): .Sp .Vb 4 \& #!perl \-w \& use AutoSplit; \& my $dir = "${MACPERL}site_perl"; \& autosplit("$dir:Some:Module.pm", "$dir:auto", 0, 1, 1); .Ve .IP "\(bu" 4 \&\fBIf you're on the \s-1DJGPP\s0 port of \s-1DOS\s0,\fR .Sp .Vb 1 \& A. DECOMPRESS .Ve .Sp djtarx ( ftp://ftp.delorie.com/pub/djgpp/current/v2/ ) will both uncompress and unpack. .Sp .Vb 1 \& B. UNPACK .Ve .Sp See above. .Sp .Vb 1 \& C.

All other periods in the filename should be replaced with underscores. For example, \&\f(CW\*(C`Your\-Module\-1.33.tar.gz\*(C'\fR should be downloaded as \&\f(CW\*(C`Your\-Module\-1_33.tgz\*(C'\fR. .Sp A. \s-1DECOMPRESS\s0 .Sp Type .Sp .Vb 1 \& gzip \-d Your\-Module.tgz .Ve .Sp or, for zipped modules, type .Sp .Vb 1 \& unzip Your\-Module.zip .Ve .Sp Executables for gzip, zip, and VMStar: .Sp .Vb 1 \& http://www.hp.com/go/openvms/freeware/ .Ve .Sp and their source code: .Sp .Vb 1 \& http://www.fsf.org/order/ftp.html .Ve .Sp Note that \s-1GNU\s0's gzip/gunzip is not the same as Info-ZIP's zip/unzip package.
