=head1 INSTALLATION
=head2 UNIX
=over 4
=item Unpack the archive
=item perl Makefile.PL
You will be asked if you want to compile in support for Apache mod_perl. If
you say yes, the source of Apache is searched (for headerfiles). If
it can't found, please specify the basepath of your Apache sources or the
directory where the Apache include files are installed. Please make sure
mod_perl is already installed. If you have installed mod_perl-0.96 or
higher, Makefile.PL automatically suggests the same source path as was
used to build mod_perl.
=item make
=item make test
=item make install
=back
B<NOTE 1:> For using session handling you need
Apache::Session 1.53 and Apache::SessionX 2.00b3 or higher.
B<NOTE 2:> I<Embperl> runs without additional Perl modules, but the C<make test>
needs the following modules to work:
=over 4
=item * URI
=item * MIME::Base64
=item * HTML::Parser
=item * HTML::HeadParser
=item * Digest::MD5
=item * libnet
=item * libwww
=item * libwin32 (only Win32)
=back
B<NOTE 3:> I<EmbperlObject> needs the following modules to work:
=over 4
=item * File::Spec 0.8 or higher
=back
If you have already successfully build and tested C<mod_perl> all modules
will already be there.
=head2 Options for make test
C<make test> can take several options, which can be given with the C<TESTARGS>
parameter:
make test TESTARGS="--help"
will show you a list of available option. Most of them you will never need,
they are mainly nesseccary for debugging I<Embperl> itself.
=head2 XML and XSLT support
Starting with Embperl 2.0b4 it has a build in XSLT support. You can either
use the Apache Xerces-C and Xalan-C and/or Gnome libxml and libxslt.
Embperl is currently tested with Xalan 1.2 and libxslt 1.0.4+.
To install Xalan, download the Xalan archive for your OS from
http://xml.apache.org/dist/xalan-c/
For Linux it is Xalan-C_1_2-linux.tar.gz
For Solaris it is Xalan-C_1_2-solaris.tar.gz
Extract the archive and make the shared libraries available to the system,
either by adding the directories to LD_LIBRARY_PATH or by coping them to
a library directory, e.g. /usr/local/lib and run ldconfig -v. The two
ncessary libraries can be found under
xerces-c1_5_1-linux/lib/libxerces-c1_5_1.so
xml-xalan/c/lib/libxalan-c1_2.so
Now you only have to enter the basepath of where you have extraced the
Xalan archive, when Makefile.PL asks you for it and proceed as normal.
B<NOTE:> For special hints on compiling XALAN see below
To use libxml/libxslt, download them from http://xmlsoft.org/ and install
them on your system. Makefile.PL will automaticly detect the installed
libraries and linked them into Embperl. (you have to make sure
that xml2-config and xslt-config can be found and run by Makefile.PL)
=head2 Debian packages
The Debian packages are maintained by Angus Lees. Here are his
installation hints:
i've also setup an apt repository for those using stable (potato). to
use it, just add these lines to /etc/apt/sources.list (deb-src line is
only necessary if you want to download the source at some point):
deb http://www.cse.unsw.edu.au/~gusl/embperl stable/binary-$(ARCH)/
deb-src http://www.cse.unsw.edu.au/~gusl/embperl stable/source/
then run "apt-get update" followed by either
"apt-get install libhtml-embperl-perl" or just "apt-get upgrade" if
you already have embperl installed.
if you don't like apt, and want to do it the old fashioned way, i'm
sure you can work out how to download the .deb manually.
notes:
currently i only have i386 packages built for stable. if anyone wants
to build other archs and let me know, i can add them in (else, i can
probably get a sparc and alpha version compiled)
the package for unstable is compiled against perl5.6, so it has to
conflict with earlier mod_perl packages that are compiled against
perl5.5. unfortunately, there is no perl5.6 apache-perl package yet
(drow assures me he's uploading one soon), so you have to make do with
a DSO mod-perl (ie: apache + libapache-mod-perl) for now.
=head2 UNIX (without Apache Source)
If you have an UNIX with preinstalled Apache and mod_perl (e.g. a Linux
distribution), you need to locate the following files on your disk:
- httpd.h
- httpd
- mod_env.so
For example in SuSE Linux 7.1 they could be found at
- /usr/include/apache/httpd.h
- /usr/sbin/httpd
- /usr/lib/apache/mod_env.so
Now go to the Embperl directory and start
perl Makefile.PL
When get asked for the Apache sources, enter the directory where you
found C<httpd.h> (e.g. C</usr/include/apache>). For the Apache executable
enter the path to C<httpd>. If the Apache modules are loaded dynamicly,
you will get ask for C<mod_env.so>, enter it's directory. Now you can
continue as normal with
make test
make install
=head2 WIN 32 (non ActiveState Perl)
B<NOTE:> You need mod_perl >= 1.12 on win32
On Windows 95/98/ME/NT/2000/XP you have to do the following:
=over 4
=item perl Makefile.PL
=item nmake (you must have the c compiler in your path)
if you get an error about compiling Embperl.c. Edit Embperl.c and change
#line "Embperl.xs"
to
#line 1 "Embperl.xs"
now re-run nmake and it should compile.
=item nmake test
B<NOTE:> C<nmake test> needs libwin32, libwww and HTML::Parser installed to work
=item nmake install
=back
B<NOTE 1:> For using session handling you need
Apache::Session 1.53 and Apache::SessionX 2.00b3 or higher.
B<NOTE 2:> I<Embperl> runs without additional Perl modules, but the C<make test>
needs the following modules to work:
=over 4
=item * URI
=item * MIME::Base64
=item * HTML::Parser
=item * HTML::HeadParser
=item * Digest::MD5
=item * libnet
=item * libwww
=item * libwin32 (only Win32)
=back
B<NOTE 3:> I<EmbperlObject> needs the following modules to work:
=over 4
=item * File::Spec 0.8 or higher
=back
If you have already successfully build and tested C<mod_perl> all modules
will already be there.
=head2 WIN 32 with ActiveState Perl
First get and install ActiveState Perl from http://www.activestate.com
You can skip the installation of Apache and mod_perl, if you only want
to use Embperl offline or as CGI.
Next get the Apache binary (e.g. apache_1.3.22-win32-x86.msi) from
http://www.apache.org/dist/httpd/binaries/win32/ . (You may need to install the
windows MSI installer from the same page too). Now run the Apache installation.
Then run the ppm program to install mod_perl
ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/mod_perl.ppd
If you get asked for the Apache directory, enter the C<modules> subdirectory under the path
where you have installed your Apache, e.g.
\Program Files\Apache Group\Apache\modules
As last step you need to install Embperl itself:
ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/HTML-Embperl.ppd
If you want to use session management, you have additionaly to install
Apache::Session and Apache::SessionX
ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/Apache-Session.ppd
ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/Apache-SessionX.ppd
=head2 Compile Embperl from the sources on WIN 32 with ActiveState Perl
First install ActiveState Perl, Apache and mod_perl as described above.
(Of course when you want to use
Embperl only offline or as CGI you don't have to install Apache and mod_perl)
Then extract the Embperl distribution and go to the directory where you have extracted
Embperl. Start
perl Makefile.PL
Enter y or hit enter when you get ask "Build with support for Apache mod_perl?(y/n) [y]"
When get asked for the Apache source enter the Apache directory you have installed above.
e.g. \Program Files\Apache Group\Apache.
Now you can continue by running
nmake test
nmake install
=head2 WIN 32: Install Apache and non Apache version on the same system
Unlike Unix, Windows loads any needed DLL (dynamic libraries) at startup. This
causes trouble when Embperl is compiled for use with Apache and mod_perl, but
is used outside of Apache, because Windows tries to load F<ApacheCore.dll>.
To solve this problem Embperl 1.3.4+ can install a Apache and a non Apache
version. To do this first install the Apache version as decribed above
(including the C<nmake install> !) .
Afterwards rerun Makefile.PL, when ask for mod_perl support answer no, now
Makefile.PL detects that a mod_perl version was already compiled and asks
if you what a separate non Apache version. Just say yes here and compile
and install this version too. When Embperl is loaded it detects if runs in-
or outside of Apache and loads the correct library.
=head2 How to continue
You can view the documentation at any time from the Embperl source directory,
by using the following commands metioned below. After the installation you can
also view documention by specifying the full module name: e.g.
perldoc HTML::Embperl, perldoc HTML::Embperl::Intro etc.
To get familiar how Embperl works, read the L<"Intro"|"Intro.pod"> and
L<"IntroEmbperlObject"|"IntroEmbperlObject.pod"> documents.
To learn how to use and configure Embperl, read the L<"Embperl documentation"|"Embperl.pod">.

=head2 Compiling XALAN
Normaly you should be fine with the binary packages that are provided for
XALAN. If you want to compile XALAN from the sources there should be normaly
no problem as long as you use GNU gcc on Unix or Microsoft VC++ on Windows.
Here are some hints how to compile XALAN 1.2 with the sun C++ 5.1:
=over 4
=item * Get the sources for XERCES and XALAN
=item * Untar the files
Use GNU tar, solaris tar doesn't work! GNU tar can be found at
ftp://ftp.mcc.ac.uk/pub/gnu/tar/tar-1.13.tar.gz
=item * Set the root directories
export XERCESCROOT=/path/to/xerces-c-src1_5_1
export XALANCROOT=/path/to/xml-xalan/c
=item * Compile XERCES
cd xerces-c-src1_5_1/src
sh runConfigure -p solaris -c cc -x CC
make
=item * Patch XALAN
There must be one typecast inserted in the following three files:
"c/src/XSLT/ExtensionFunctionHandler.cpp", line 156
156c156
< return m_functions.find(function) != m_functions.end();
---
> return StringSetType::const_iterator(m_functions.find(function)) != m_functions.end();
"c/src/XSLT/ExtensionNSHandler.cpp", line 200
200c200
< return (m_elements.find(element) != m_elements.end());
---
> return (ExtensionSetType::const_iterator(m_elements.find(element)) != m_elements.end());
"c/src/XSLT/NamespacesHandler.cpp", line 366
366c366
< || m_extensionNamespaceURIs.find(theURI) != m_extensionNamespaceURIs.end()
---
> || ExtensionNamespaceURISetType::const_iterator(m_extensionNamespaceURIs.find(theURI)) != m_extensionNamespaceURIs.end()
=item * Compile XALAN
cd xml-xalan/c/src
sh runConfigure -p solaris -c cc -x CC -z "-D__GNUC__"
make
B<NOTE:> I found that only the above parameters to configure work.
Don't worry that __GNUC__ is defined. It works with sun C++ 5.1.
When using sun C++ 5.1 you don't need the STLPort template library.
=item * Make the libraries available
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/xerces-c-src1_5_1/lib:/path/to/xml-xalan/c/lib
=item * Now you can run Embperl's Makefile.PL as described above
