INSTALLATION

UNIX

To install on unix perform the following steps:

Prerequisite

Here are a lit of packages you should install for getting Embperl to work. mod_perl, Apache::Session, Apache::SessionX, libxml2, libxlst are optional and need only to be install when you require their functionality.

debian & ubunutu

debian comes with the package `libembperl-perl/stable 2.5.0-17 amd64`. So just run

sudo apt install libembperl-perl

and you are done. If you want to install a newer version from the source, continue to read. Install prerequistite

sudo apt update 
sudo apt -y install libextutils-xsbuilder-perl libapache2-mod-perl2-dev apache2-dev \
  libcgi-pm-perl libapache-sessionx-perl libextutils-pkgconfig-perl libxml2-dev libxslt1-dev

fedora

Not all module are available as precomipled packages, so you have to install some from cpan:

yum -y install mod_perl-devel perl-Apache-Session perl-ExtUtils-PkgConfig || exit 1
cpan LWP::UserAgent 
cpan ExtUtils::XSBuilder
cpan -f Apache::SessionX

almalinux

yum -y install epel-release # required for mod_perl
dnf --enablerepo=epel -y install mod_perl-devel perl-Apache-Session perl-ExtUtils-PkgConfig
cpan LWP::UserAgent
cpan ExtUtils::XSBuilder
cpan -f Apache::SessionX

amazon linux

yum -y install mod_perl-devel perl-Apache-Session perl-ExtUtils-PkgConfig || exit 1
cpan LWP::UserAgent 
cpan ExtUtils::XSBuilder
cpan -f Apache::SessionX

Installing from source

You can download Embperl from CPAN or from https://www.embperl.org/downloads

Beta Versions and release candidates are only available from https://www.embperl.org/downloads

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. 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:

  • URI

  • MIME::Base64

  • HTML::Parser

  • HTML::HeadParser

  • Digest::MD5

  • libnet

  • libwww

  • libwin32 (only Win32)

NOTE 3: EmbperlObject needs the following modules to work:

  • File::Spec 0.8 or higher

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 use Gnome libxml and libxslt. Embperl is currently tested with libxslt 1.0.4 and newer.

To use libxml/libxslt, download them from https://xmlsoft.org/ and install them on your system. Makefile.PL will automatically 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 "libhtml-embperl-perl" and "libembperl-perl" are are available from the usual Debian mirrors.

To compile Embperl you need to install apache2-dev and libapache2-mod-perl2-dev.

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, in case Makefile.PL does not find them automatically:

httpd.h
httpd
mod_env.so

For example they could be found at

/usr/include/apache/httpd.h
/usr/sbin/httpd
/usr/lib/apache/mod_env.so

In most cases it is sufficent to have to apache-dev and mod_perl-dev packages from your favourite Linux distribution installed.

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, the you will get ask for mod_env.so, enter it's directory. Now you can continue as normal with

make test
make install

Win32 (non ActiveState Perl)

NOTE: You need mod_perl >= 1.12 on win32

On Windows 95/NT 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:

  • URI

  • MIME::Base64

  • HTML::Parser

  • HTML::HeadParser

  • Digest::MD5

  • libnet

  • libwww

  • libwin32 (only Win32)

NOTE 3: EmbperlObject needs the following modules to work:

  • File::Spec 0.8 or higher

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

Win32 with ActiveState Perl and Apache 1.3.x

First get and install ActiveState Perl from https://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 (including the source e.g. apache_1.3.31-win32-x86-src.msi) from https://www.apache.org/dist/httpd/binaries/win32/ or a mirror. (You may need to install the windows MSI installer from the same page too, and be sure to read the README at the end of the file list for further requirements of some windows versions, especially Windows 95 and XP). Now run the installation.

Then install mod_perl. How to do this is described very detailed at https://perl.apache.org/docs/1.0/os/win32/install.html#PPM_Packages

In this file, you'll find a short summary of that page.

There are two ways to install mod_perl:

+ Easy version:

Download the perl script
https://perl.apache.org/docs/1.0/os/win32/mpinstall and execute it
with "perl mpinstall". It will interactively install you the right
mod_perl version.

+ Manual installation:

Run the ppm program to install mod_perl

- If you have Perl 5.8.x:

  ppm install https://theoryx5.uwinnipeg.ca/ppms/mod_perl-1.ppd

- If you have Perl 5.6.x:

  ppm install https://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 can install the Embperl ppd:

+ If you have Perl 5.8.x:

  ppm install https://theoryx5.uwinnipeg.ca/ppms/Embperl-1.ppd

This is an Embperl 2 ppd, the "-1" at the end of the package name
denotes that this ppd is for mod_perl 1.x. There is no Embperl 1 ppd
for Perl 5.8.x (yet).

+ If you have Perl 5.6.x:

- Embperl 1:

  ppm install https://theoryx5.uwinnipeg.ca/ppmpackages/HTML-Embperl.ppd

- Embperl 2:

  ppm install https://theoryx5.uwinnipeg.ca/ppmpackages/Embperl.ppd

Compile Embperl from the sources on Win32 with ActiveState Perl

First install ActiveState Perl, Apache and mod_perl as described above. Make sure you have an Apache version which includes the sources. (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.

Now you can continue by running

nmake test
nmake install

Win32: 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 (includeing 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 separte 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.

Win32: Apache 2.0

Embperl currently does not support Apache 2.0 on Windows (on UNIX is does). This is due to the fact the Embperl is not fully thread safe yet. Makeing Embperl thread safe and support for Apache 2.0 on Windows, is currently under development.

How to continue

IMPORTANT: Before using Embperl 2.0, make sure you have read the README.v2. The documentation is only partially updated to 2.0 yet!!

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 Embperl, perldoc 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".
