.Vb 1
\&  unzip perl_man.zip \-d f:/perllib/man

.Sp
This directory should better be on \f(CW\*(C`MANPATH\*(C'\fR. You need to have a
working \fIman\fR to access these files.
.IP "Manpages for Perl modules" 3

.Vb 1
\&  unzip perl_mam.zip \-d f:/perllib/man
.Ve

This directory should better be on \f(CW\*(C`MANPATH\*(C'\fR. You need to have a

.IP "Source for Perl documentation" 3
.IX Item "Source for Perl documentation"
.Vb 1
\&  unzip perl_pod.zip \-d f:/perllib/lib
.Ve
.Sp
This is used by the \f(CW\*(C`perldoc\*(C'\fR program (see perldoc), and may be used to
generate \s-1HTML\s0 documentation usable by \s-1WWW\s0 browsers, and
documentation in zillions of other formats: \f(CW\*(C`info\*(C'\fR, \f(CW\*(C`LaTeX\*(C'\fR,
\&\f(CW\*(C`Acrobat\*(C'\fR, \f(CW\*(C`FrameMaker\*(C'\fR and so on.  [Use programs such as
\&\fIpod2latex\fR etc.]

This directory should better be on \f(CW\*(C`BOOKSHELF\*(C'\fR.
.IP "Pdksh" 3
.IX Item "Pdksh"
.Vb 1
\&  unzip perl_sh.zip \-d f:/bin
.Ve
.Sp
This is used by perl to run external commands which explicitly
require shell, like the commands using \fIredirection\fR and \fIshell
metacharacters\fR. It is also used instead of explicit \fI/bin/sh\fR.
.Sp
Set \f(CW\*(C`PERL_SH_DIR\*(C'\fR (see \*(L"\s-1PERL_SH_DIR\s0\*(R") if you move \fIsh.exe\fR from
the above location.
.Sp
\&\fBNote.\fR It may be possible to use some other sh-compatible shell (untested).
.PP
After you installed the components you needed and updated the
\&\fIConfig.sys\fR correspondingly, you need to hand-edit
\&\fIConfig.pm\fR. This file resides somewhere deep in the location you
installed your perl library, find it out by
.PP
.Vb 1
\&  perl \-MConfig \-le "print $INC{\*(AqConfig.pm\*(Aq}"
.Ve
.PP
You need to correct all the entries which look like file paths (they
currently start with \f(CW\*(C`f:/\*(C'\fR).
.Sh "\fBWarning\fP"
.IX Subsection "Warning"
The automatic and manual perl installation leave precompiled paths
inside perl executables. While these paths are overwriteable (see
\&\*(L"\s-1PERLLIB_PREFIX\s0\*(R", \*(L"\s-1PERL_SH_DIR\s0\*(R"), some people may prefer
binary editing of paths inside the executables/DLLs.
.SH "Accessing documentation"
.IX Header "Accessing documentation"
Depending on how you built/installed perl you may have (otherwise
identical) Perl documentation in the following formats:
.Sh "\s-1OS/2\s0 \fI.INF\fP file"
.IX Subsection "OS/2 .INF file"
Most probably the most convenient form. Under \s-1OS/2\s0 view it as
.PP
.Vb 4
\&  view perl
\&  view perl perlfunc
\&  view perl less
\&  view perl ExtUtils::MakeMaker
.Ve
.PP
(currently the last two may hit a wrong location, but this may improve
soon). Under Win* see \*(L"\s-1SYNOPSIS\s0\*(R".
.PP
If you want to build the docs yourself, and have \fI\s-1OS/2\s0 toolkit\fR, run
.PP
.Vb 1
\&        pod2ipf > perl.ipf
.Ve
.PP
in \fI/perllib/lib/pod\fR directory, then
.PP
.Vb 1
\&        ipfc /inf perl.ipf
.Ve
.PP
(Expect a lot of errors during the both steps.) Now move it on your
\&\s-1BOOKSHELF\s0 path.
.Sh "Plain text"
.IX Subsection "Plain text"
If you have perl documentation in the source form, perl utilities
installed, and \s-1GNU\s0 groff installed, you may use
.PP
.Vb 3
\&        perldoc perlfunc
\&        perldoc less
\&        perldoc ExtUtils::MakeMaker
.Ve
.PP
to access the perl documentation in the text form (note that you may get
better results using perl manpages).
.PP
Alternately, try running pod2text on \fI.pod\fR files.
.Sh "Manpages"
.IX Subsection "Manpages"
If you have \fIman\fR installed on your system, and you installed perl
manpages, use something like this:
.PP
.Vb 3
\&        man perlfunc
\&        man 3 less
\&        man ExtUtils.MakeMaker
.Ve
.PP
to access documentation for different components of Perl. Start with
.PP
.Vb 1
\&        man perl
.Ve
.PP
Note that dot (\fI.\fR) is used as a package separator for documentation
for packages, and as usual, sometimes you need to give the section \- \f(CW3\fR
above \- to avoid shadowing by the \fI\fIless\fI\|(1) manpage\fR.
.PP
Make sure that the directory \fBabove\fR the directory with manpages is
on our \f(CW\*(C`MANPATH\*(C'\fR, like this
.PP
.Vb 1
\&  set MANPATH=c:/man;f:/perllib/man
.Ve
.PP
for Perl manpages in \f(CW\*(C`f:/perllib/man/man1/\*(C'\fR etc.
.Sh "\s-1HTML\s0"
.IX Subsection "HTML"
If you have some \s-1WWW\s0 browser available, installed the Perl
documentation in the source form, and Perl utilities, you can build
\&\s-1HTML\s0 docs. Cd to directory with \fI.pod\fR files, and do like this
.PP
.Vb 2
\&        cd f:/perllib/lib/pod
\&        pod2html
.Ve
.PP
After this you can direct your browser the file \fIperl.html\fR in this
directory, and go ahead with reading docs, like this:
.PP
.Vb 1
\&        explore file:///f:/perllib/lib/pod/perl.html
.Ve
.PP
Alternatively you may be able to get these docs prebuilt from \s-1CPAN\s0.
.ie n .Sh "\s-1GNU\s0 ""info"" files"
.el .Sh "\s-1GNU\s0 \f(CWinfo\fP files"
.IX Subsection "GNU info files"
Users of Emacs would appreciate it very much, especially with
\&\f(CW\*(C`CPerl\*(C'\fR mode loaded. You need to get latest \f(CW\*(C`pod2texi\*(C'\fR from \f(CW\*(C`CPAN\*(C'\fR,
or, alternately, the prebuilt info pages.
.Sh "\fI\s-1PDF\s0\fP files"
.IX Subsection "PDF files"
for \f(CW\*(C`Acrobat\*(C'\fR are available on \s-1CPAN\s0 (may be for slightly older version of
perl).
.ie n .Sh """LaTeX"" docs"
.el .Sh "\f(CWLaTeX\fP docs"
.IX Subsection "LaTeX docs"
can be constructed using \f(CW\*(C`pod2latex\*(C'\fR.
.SH "BUILD"
.IX Header "BUILD"
Here we discuss how to build Perl under \s-1OS/2\s0. There is an alternative
(but maybe older) view on <http://www.shadow.net/~troc/os2perl.html>.
.Sh "The short story"
.IX Subsection "The short story"
Assume that you are a seasoned porter, so are sure that all the necessary
tools are already present on your system, and you know how to get the Perl
source distribution.  Untar it, change to the extract directory, and
.PP
.Vb 7
\&  gnupatch \-p0 < os2\ediff.configure
\&  sh Configure \-des \-D prefix=f:/perllib
\&  make
\&  make test
\&  make install
\&  make aout_test
\&  make aout_install
.Ve
.PP
This puts the executables in f:/perllib/bin.  Manually move them to the
\&\f(CW\*(C`PATH\*(C'\fR, manually move the built \fIperl*.dll\fR to \f(CW\*(C`LIBPATH\*(C'\fR (here for
Perl \s-1DLL\s0 \fI*\fR is a not-very-meaningful hex checksum), and run
.PP
.Vb 1
\&  make installcmd INSTALLCMDDIR=d:/ir/on/path
.Ve
.PP
Assuming that the \f(CW\*(C`man\*(C'\fR\-files were put on an appropriate location,
this completes the installation of minimal Perl system.  (The binary
distribution contains also a lot of additional modules, and the
documentation in \s-1INF\s0 format.)
.PP
What follows is a detailed guide through these steps.
.Sh "Prerequisites"
.IX Subsection "Prerequisites"
You need to have the latest \s-1EMX\s0 development environment, the full
\&\s-1GNU\s0 tool suite (gawk renamed to awk, and \s-1GNU\s0 \fIfind.exe\fR
earlier on path than the \s-1OS/2\s0 \fIfind.exe\fR, same with \fIsort.exe\fR, to
check use
.PP
.Vb 2
\&  find \-\-version
\&  sort \-\-version
.Ve
.PP
). You need the latest version of \fIpdksh\fR installed as \fIsh.exe\fR.
.PP
Check that you have \fB\s-1BSD\s0\fR libraries and headers installed, and \- 
optionally \- Berkeley \s-1DB\s0 headers and libraries, and crypt.
.PP
Possible locations to get the files:
.PP
.Vb 4
\&  ftp://hobbes.nmsu.edu/os2/unix/
\&  ftp://ftp.cdrom.com/pub/os2/unix/
\&  ftp://ftp.cdrom.com/pub/os2/dev32/

It is reported that the following archives contain enough utils to
build perl: \fIgnufutil.zip\fR, \fIgnusutil.zip\fR, \fIgnututil.zip\fR, \fIgnused.zip\fR,
\&\fIgnupatch.zip\fR, \fIgnuawk.zip\fR, \fIgnumake.zip\fR, \fIgnugrep.zip\fR, \fIbsddev.zip\fR and
\&\fIksh527rt.zip\fR (or a later version).  Note that all these utilities are
known to be available from \s-1LEO:\s0
.PP
.Vb 1
\&  ftp://ftp.leo.org/pub/comp/os/os2/leo/gnu
.Ve
.PP
Note also that the \fIdb.lib\fR and \fIdb.a\fR from the \s-1EMX\s0 distribution
are not suitable for multi-threaded compile (even single-threaded
flavor of Perl uses multi-threaded C \s-1RTL\s0, for
compatibility with XFree86\-OS/2). Get a corrected one from
.PP
.Vb 1
\&  http://www.ilyaz.org/software/os2/db_mt.zip
.Ve
.PP
If you have \fIexactly the same version of Perl\fR installed already,
make sure that no copies or perl are currently running.  Later steps
of the build may fail since an older version of \fIperl.dll\fR loaded into
memory may be found.  Running \f(CW\*(C`make test\*(C'\fR becomes meaningless, since
the test are checking a previous build of perl (this situation is detected
and reported by \fIlib/os2_base.t\fR test).  Do not forget to unset
\&\f(CW\*(C`PERL_EMXLOAD_SEC\*(C'\fR in environment.
.PP
Also make sure that you have \fI/tmp\fR directory on the current drive,
and \fI.\fR directory in your \f(CW\*(C`LIBPATH\*(C'\fR. One may try to correct the
latter condition by
.PP
.Vb 1
\&  set BEGINLIBPATH .\e.
.Ve
.PP
if you use something like \fI\s-1CMD\s0.EXE\fR or latest versions of
\&\fI4os2.exe\fR.  (Setting \s-1BEGINLIBPATH\s0 to just \f(CW\*(C`.\*(C'\fR is ignored by the
\&\s-1OS/2\s0 kernel.)
.PP
Make sure your gcc is good for \f(CW\*(C`\-Zomf\*(C'\fR linking: run \f(CW\*(C`omflibs\*(C'\fR
script in \fI/emx/lib\fR directory.
.PP
Check that you have link386 installed. It comes standard with \s-1OS/2\s0,
but may be not installed due to customization. If typing
.PP
.Vb 1
\&  link386
.Ve
.PP
shows you do not have it, do \fISelective install\fR, and choose \f(CW\*(C`Link
object modules\*(C'\fR in \fIOptional system utilities/More\fR. If you get into
link386 prompts, press \f(CW\*(C`Ctrl\-C\*(C'\fR to exit.
.Sh "Getting perl source"
.IX Subsection "Getting perl source"
You need to fetch the latest perl source (including developers
releases). With some probability it is located in
.PP
.Vb 2
\&  http://www.cpan.org/src/5.0
\&  http://www.cpan.org/src/5.0/unsupported
.Ve
.PP
If not, you may need to dig in the indices to find it in the directory
of the current maintainer.
.PP
Quick cycle of developers release may break the \s-1OS/2\s0 build time to
time, looking into
.PP
.Vb 1
\&  http://www.cpan.org/ports/os2/
.Ve
.PP
may indicate the latest release which was publicly released by the
maintainer. Note that the release may include some additional patches
to apply to the current source of perl.
.PP
Extract it like this
.PP
.Vb 1
\&  tar vzxf perl5.00409.tar.gz
.Ve
.PP
You may see a message about errors while extracting \fIConfigure\fR. This is
because there is a conflict with a similarly-named file \fIconfigure\fR.
.PP
Change to the directory of extraction.
