INSTALLATION ^

UNIX

Unpack the archive
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.

make
make test
make install

NOTE 1: For using session handling you need Apache::Session 1.53 and Apache::SessionX 2.00b3 or higher.

NOTE 2: Embperl runs without additional Perl modules, but the make test needs the following modules to work:

NOTE 3: EmbperlObject needs the following modules to work:

If you have already successfully build and tested mod_perl all modules will already be there.

Options for make test

make test can take several options, which can be given with the 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 Embperl itself.

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.

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)

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.

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 httpd.h (e.g. /usr/include/apache). For the Apache executable enter the path to httpd. If the Apache modules are loaded dynamicly, you will get ask for mod_env.so, enter it's directory. Now you can continue as normal with

 make test
 make install

WIN 32 (non ActiveState Perl)

NOTE: You need mod_perl >= 1.12 on win32

On Windows 95/98/ME/NT/2000/XP you have to do the following:

perl Makefile.PL
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.

nmake test

NOTE: nmake test needs libwin32, libwww and HTML::Parser installed to work

nmake install

NOTE 1: For using session handling you need Apache::Session 1.53 and Apache::SessionX 2.00b3 or higher.

NOTE 2: Embperl runs without additional Perl modules, but the make test needs the following modules to work:

NOTE 3: EmbperlObject needs the following modules to work:

If you have already successfully build and tested mod_perl all modules will already be there.

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 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

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  

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 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 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.

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 "Intro" and "IntroEmbperlObject" documents. To learn how to use and configure Embperl, read the "Embperl documentation".

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:
