   1.6. Installing Under MacOS X

        1.6.1. Can I run Lire under MacOSX? 

   In this section, you will find answers to common installation problems
   on various platforms.

1.1. Installing Under Debian GNU/Linux

   1.1.1. What .deb packages are required by Lire?

   1.1.1. 

   What .deb packages are required by Lire?
   
   The Lire .deb has the proper Suggests and Depends tags that will give
   you the proper dependencies. But if you would like to install Lire
   from source, read on.

   To run a minimum Lire installation, you will need the following
   packages (those are from Woody):
     * libxml-parser-perl

   and its other dependencies.

   To run a Lire installation with all the output format supported, you
   will also need:
     * jade or openjade
     * docbook-xml
     * docbook-dsssl
     * docbook-xsl-stylesheets
     * xsltproc
     * jadetex
     * libgd-graph-perl

   and their other dependencies.

1.2. Installing Under Red Hat Linux

   1.2.1. What RPM packages should I install to run Lire? 

   1.2.1. 

   What RPM packages should I install to run Lire?
   
   To install a minimum Lire installation, you will need the following
   packages:
     * perl-XML-Parser

   along with its required dependencies.

   To run a Lire installation with all the output format supported, you
   will also need:
     * openjade
     * docbook-dtd412-xml
     * docbook-style-dsssl
     * docbook-style-xsl
     * libxslt
     * jadetex

   and their other dependencies.

   In order to generate charts, you will need to install the following
   perl modules from a CPAN mirror:
     * GD
     * GDGraph

   To compile those modules, in addition to the usual development
   packages, you will need:
     * gd
     * gd-devel

1.3. Installing Under SuSE Linux

   1.3.1. What RPM packages should I install to run Lire? 
   1.3.2. I have installed all the requirements but I get the following
          errors when trying to generate an HTML report:
          /usr/bin/jade:/home/lire/logreport/share/lire/sgml/stylesheet/d
          sssl/\ html.dsl+:1:73:W: cannot generate system identifier for
          public text\ "-//James Clark//DTD+DSSSL Style Sheet//EN What
          does this means ? 

   1.3.1. 

   What RPM packages should I install to run Lire?
   
   To install a minimum Lire installation, you will need the following
   packages that are available from your SuSE Linux installation CD:
     * perl-XML-Parser

   along with its required dependencies.

   To run a Lire installation with all the output formats supported, you
   will also need the following packages (all included on the
   installation CD):
     * openjade or jade_dsl
     * docbook_4
     * docbook-dsssl-stylesheets
     * docbook-xsl-stylesheets
     * jadetex

   and their other dependencies.

   You will also need to install an RPM for libxslt and libxml2 that
   aren't packaged with SuSE Linux. You can install the ones distributed
   by the author of libxslt and available from ftp://xmlsoft.org/

   In order to generate charts, you will need to install the following
   perl module from a CPAN mirror:
     * GDGraph.

   Before installing that module, you will have to install the following
   packages from the SuSE Linux CD:
     * perl-GD
     * gd
     * gd-devel

   1.3.2. 

   I have installed all the requirements but I get the following errors
   when trying to generate an HTML report:
/usr/bin/jade:/home/lire/logreport/share/lire/sgml/stylesheet/dsssl/\
 html.dsl+:1:73:W: cannot generate system identifier for public text\
 "-//James Clark//DTD+DSSSL Style Sheet//EN


   What does this means ?
   
   The SGML environment isn't properly set when using openjade under SuSE
   Linux. You will have to set the SGML_CATALOG_FILES environment
   variable to the following:
$ export SGML_CATALOG_FILES="/usr/share/sgml/CATALOG.db41xml:\
>/usr/share/sgml/CATALOG.docbook-dsssl-stylesheets:\
>/usr/share/sgml/openjade/catalog"


   Please report this as a packaging bug to SuSE Linux.

1.4. Installing Under OpenBSD

   1.4.1. Which ports should I install to run Lire? 

   1.4.1. 

   Which ports should I install to run Lire?
   
   All the software required to run Lire is available in the OpenBSD 3.1
   ports collection.

   To run a minimum Lire installation, you can install the following
   port:
     * p5-XML-Parser

   To run a Lire installation with all the output format supported, the
   following ports can be installed:
     * openjade
     * docbook-modular
     * jadetex
     * expat
     * libxslt
     * p5-GD-Graph
     * p5-MIME-tools (for lr_log2mail, a.o.)

   and their other dependencies.

   You will also need to install the DocBook XML DTD and Norman Walsh's
   DocBook XSL stylesheets from source.
   
   For OpenBSD 2.9 (and 2.10 too, probably) one can do with the following
   ports:

   To run a minimum Lire installation, you can install the following
   port:
     * p5-XML-Parser

   To run a Lire installation with all the output formats supported, the
   following ports can be installed:
     * openjade
     * docbook
     * docbook-modular
     * jadetex
     * p5-GD-Graph

   and their other dependencies.

   Although libxslt and libxml2 are included in the 2.9 ports collection,
   they are older versions which aren't supported by Lire.

   You will need to install libxslt 1.0.4 (or newer) from source.

   You will need to use GNU make to install libxml2 because it breaks
   with OpenBSD's native make.

   You will also need to install Norman Walsh's DocBook XSL stylesheets
   from source.

1.5. Installing Under Solaris

   1.5.1. Which packages should I install to run Lire? 
   1.5.2. Is it hard to install the needed libxslt?
   1.5.3. How do I install OpenJade?
   1.5.4. How do I install Jade? 
   1.5.5. While trying to generate an HTML report using lr_log2report -o
          html, I get the error following error all all
          lr_tag-20011013213208-983 lr_xml2html err docbook.dsl \ file ''

          Lire \ User's Manual for more informations. How do I fix this
          problem ? 

   1.5.6. I installed the necessary DocBook stuff, but generation of HTML
          reports still fails with the message: bogus message: cat:
          cannot open /usr/home/flacoste/tmp/lr_xml2html.6050/\
          lr_xml2html.html www combined lr_tag-20011013215447-6006
          lr_log2report err lr_xml2html failed How do I solve this
          problem? 

   1.5.1. 

   Which packages should I install to run Lire?
   
   Unfortunately, most of the required tools aren't available as Solaris
   packages. The only ones that you will find on SunFreeWare are:

   DB_File, db
          Needed if you want to anonymize logs before sending them an
          online responder.

   Fortunately, most development packages that you will need to build the
   other requirements are available as packages:
     * GNU make
       zlib
       gcc
       gd
       teTeX

   The following requirements will have to be compiled from source:
     * perl GD module
     * perl GDGraph module
     * libxslt
     * libxml2
     * jade
     * jadetex

   1.5.2. 

   Is it hard to install the needed libxslt?
   
   We successfully installed libxslt on a SPARCstation-20 running SunOS
   5.7, using GNU make and gcc 2.8.1. We used libxml2-2.4.5.tar.gz and
   libxslt-1.0.4.tar.gz.

   Apart from having to set our LD_LIBRARY_PATH to
   /usr/lib:/usr/local/lib (our libz from zlib-1.1.3, in
   /usr/local/lib/libz.a and /usr/local/lib/libz.so), and to set our PATH
   to include /usr/ccs/bin (to find ranlib), no issues arose.
   1.5.3. 

   How do I install OpenJade?
   
   There are some issues with OpenJade. In case you get hit by something
   like :
c++ -O2 -fno-implicit-templates -I. -I./../include -I./../generic \
  -DSTDC_HEADERS=1 -DHAVE_LIMITS_H=1 -DHAVE_ST_BLKSIZE=1 -DSIZEOF_SIZE_T=4 \
  -DSIZEOF_UNSIGNED_INT=4 -DSP_HAVE_BOOL=1 -DSP_HAVE_LOCALE=1 \
  -DSP_HAVE_GETTEXT=1 -DSP_ANSI_CLASS_INST=1 -DJADE_MIF=1 -DJADE_HTML=1 \
  -DSP_MULTI_BYTE=1 \
  -DDEFAULT_SCHEME_BUILTINS=\"/usr/local/share/builtins.dsl\" -c  -fPIC \
  -DPIC TranslateCodingSystem.cxx -o TranslateCodingSystem.lo
TranslateCodingSystem.cxx: In method \
 `TranslateDecoder::TranslateDecoder(class Decoder *, const class \
 ConstPtr&lt;CharMapResource&lt;short unsigned int&gt; &gt; &amp;)':
TranslateCodingSystem.cxx:28: Internal compiler error.
TranslateCodingSystem.cxx:28: Please submit a full bug report to \
 `bug-g++@prep.ai.mit.edu'.
make[2]: *** [TranslateCodingSystem.lo] Error 1


   there's a workaround, reported by Carlos Villegas on
   dssslist@lists.mulberrytech.com, which can be implemented by running:
$ CXXFLAGS=' ' ./configure
$ make
# make install


Note

   This problem may be specific to gcc 2.8.1.

   1.5.4. 

   How do I install Jade?
   
   In case you're running something like SunOS 5.7, you're advised to not
   install OpenJade, but Jade. OpenJade is reported to segfault. We've
   successfully installed Jade on such a machine. In order to build jade,
   we modified the Makefile to feature:
prefix=/usr/local
XDEFINES=-DSP_HAVE_GETTEXT -DSP_DECLARE_H_ERRNO
RANLIB=ranlib

   Test your installation by running:
$ jade -t rtf -d demo.dsl demo.sgm


   and inspecting the generated demo.rtf.
   1.5.5. 

   While trying to generate an HTML report using lr_log2report -o html, I
   get the error following error
all all lr_tag-20011013213208-983 lr_xml2html err docbook.dsl \
 file '' does not exist!
all all lr_tag-20011013213208-983 lr_xml2html err Please install \
 Norman Walsh's DocBook DSSSL Stylesheets.
all all lr_tag-20011013213208-983 lr_xml2html err Consult the Lire \
 User's Manual for more informations.


   How do I fix this problem ?
   
   You need to install the following software:
     * DocBook XML DTD 4.1.2. Available from
       http://www.docbook.org/xml/4.1.2/docbkx412.zip.

     * Norman Walsh's DocBook DSSSL Stylesheets. You can download these
       from
       http://prdownloads.sourceforge.net/docbook/docbook-dsssl-1.73.tar.
       gz.

     * Norman Walsh's DocBook XSL Stylesheets. You can download these
       from
       http://prdownloads.sourceforge.net/docbook/docbook-xsl-1.45.tar.gz

   You only have to unpack the files in a directory. Both the DocBook DTD
   distribution and the DSSSL stylesheets come with a OASIS catalog that
   you probably want to add to your SGML_CATALOG_FILES. (See next
   question for more informations.)

   Lire tries to find those components in `standard' places like
   /usr/share/sgml or /usr/lib/sgml. When configuring Lire, you should
   point it to the locations where you unpacked those files by using
   environmental variables:
$ DBK_XML_DTD="docbook_dtd_directory/docbookx.dtd" \
> DBK_DSSSL_STYLESHEETS="docbook_dsssl_directory" \
> DBK_XSL_STYLESHEETS="docbook_xsl_directory" \
./configure other-options


   1.5.6. 

   I installed the necessary DocBook stuff, but generation of HTML
   reports still fails with the message:
bogus message: cat: cannot open /usr/home/flacoste/tmp/lr_xml2html.6050/\
 lr_xml2html.html
www combined lr_tag-20011013215447-6006 lr_log2report err lr_xml2html failed


   How do I solve this problem?
   
   This is probably because jade cannot find the DocBook DTD or the DSSSL
   stylesheets. You can set the LR_DEBUG variable to 1 in your
   $HOME/.lire/etc/defaults file to make sure. If this is indeed the
   error, you will get the following in the messages output by Lire:
all all lr_tag-20011013215935-6210 lr_xml2html info /usr/local/bin/jade \
 says /usr/local/bin/jade:/usr/home/flacoste/lire-test/share/lire/sgml/\
 stylesheet/dsssl/html.dsl:1:73:W: cannot generate system identifier for \
 public text "-//James Clark//DTD DSSSL Style Sheet//EN"
all all lr_tag-20011013215935-6210 lr_xml2html info /usr/local/bin/jade \
 says /usr/local/bin/jade:/usr/home/flacoste/lire-test/share/lire/sgml/\
 stylesheet/dsssl/html.dsl:2:91:W: cannot generate system identifier for \
 public text "-//Norman Walsh//DOCUMENT DocBook HTML Stylesheet//EN"


   For jade to find the necessary `public identifiers', you will need to
   set your SGML_CATALOG_FILES to point to the necessary `OASIS
   catalogs'. This variable will need to contain at least the three
   following catalogs:
     * Catalog for DocBook XML DTD: it is in
       docbook_dtd_directory/docbook.cat.
     * Catalog that comes with Jade or OpenJade:
       jade_source_directory/dsssl/catalog.
     * Catalog that comes with Norman Walsh's DSSSL Stylesheets:
       docbook_dsssl_directory/catalog.

   So doing
$ export SGML_CATALOG_FILES="docbook_dtd_directory/docbook.cat:\
> docbook_dsssl_directory/catalog:\
> docbook_dsssl_directory/catalog"


   will probably fix the problem. Be sure to replace the
   docbook_dtd_directory and such with the actual directories where you
   installed the DocBook DTD.

1.6. Installing Under MacOS X

   1.6.1. Can I run Lire under MacOSX? 

   1.6.1. 

   Can I run Lire under MacOSX?
   
   Yes! Lire version 20011017 and later (some earlier versions too,
   probably) builds and runs under MacOSX 10.1. This has not been
   anywhere near fully tested and many features are dodgy at best.
   However, here's what you need to do to get the basic package cooking.
   This assumes some familiarity with the terminal application and
   command line interface. You'll also obviously need to have the
   developers tools installed.
     * Open a terminal window. Download and de-compress the latest lire
       package by typing the following:
$ curl http://www.logreport.org/pub/current.tar.gz
$ tar -xzvf current.tar.gz

       DO NOT decompress with StuffIt Expander. This will result in a
       broken package!
     * Then cd into the directory this creates (should be lire-20011205)
       and run the configuration utility with the --prefix option. Then
       make and make install. You can change this to wherever you want to
       install. This will create a logreport folder in your home
       directory which holds all the lire software. You might also try
       --prefix=$HOME/Applications/lire
$ ./configure --prefix=$HOME/logreport
<blah blah>
$ make
<blah blah>
$ make install

     * Now the software is in. The next step is to make your shell aware
       of it. Remember the prefix you picked above.
$ pico ~/.tcshrc

       Now add the following lines to the .tcshrc file (this is read by
       your shell whenever you log in). Then press ctrl+X to exit. Answer
       y for yes to save and hit return to write the file.
setenv PATH {$PATH}:$HOME/logreport/bin
setenv MANPATH {$MANPATH}:$HOME/logreport/man

     * Now close this shell and open a new one. You're ready to use lire.
       There are man pages to help, and a user manual is installed. The
       apache logs generated by default in OSX (in /var/log/httpd/) are
       readable by lire. You can analyze access_log as a www common file.
       This FAQ section will improve in the future as we are able to play
       with OS 10.1 more in the future.

2. Licensing

   2.1. I wanna contribute code, and would like it to get distributed as
          a part of Lire, what should I do, license-wise?

   2.2. Why is Lire licensed under the GPL?
   2.3. If I make a contribution to Lire do I have to put my code under
          the GPL? 

   2.4. We want to write a DLF converter for the users of our proprietary
          product, can we distribute it under the same proprietary terms
          as our other products? 

   2.5. Can I distribute my XML report specifications under other terms
          than the GPL? 

   2.6. I want to reuse your file formats (DLF format, XML report) in my
          project, but I want to release this project under a MIT X-like
          license, may I? 

   In this section, you will find answers to common questions about
   various aspects of Lire's licensing, e.g. questions which might arise
   if you plan to extend Lire with your own code.

   Be aware that the LogReport team is very happy to include and maintain
   contributed code. We want to make this as easy as possible. See the
   first question. If you write code to be used with or as a part of
   Lire, please consider contributing it. This will not only benefit
   Stichting LogReport Foundation, but also you: the LogReport team will
   maintain and distribute your code, and will take care of handling bug
   reports.

   2.1. 

   I wanna contribute code, and would like it to get distributed as a
   part of Lire, what should I do, license-wise?
   
   As with any software, it's a good thing to add a copyright notice to
   your code, like

    Copyright (C) 2001,2002 Joe Hacker joe@example.org

   . This makes it easy to find out who holds the copyright of this
   particular piece of code. Furthermore, you should add a license
   notice, like e.g. the modified BSD license which reads

    Redistribution and use in source and binary forms, with or without
    modification, are permitted provided that the following conditions ar
   e met:

   or a referal to the GPL, which reads

   This program is free software; you can redistribute it and/or modify
   it under the terms of the GNU General Public License as published by
   the Free Software Foundation; either version 2 of the License, or
   (at your option) any later version.

   This makes it clear what people are allowed to do with your code. See
   the questions below for other licenses you could use. If you sent us
   code along with a copyright notice ans license notice as above, we
   have no problems licence-wise with your contribution.
   2.2. 

   Why is Lire licensed under the GPL?
   
   The Stichting LogReport Foundation exists to develop, maintain and
   propagate tools as well as knowledge for log file processing and
   report generation (among other things). The Foundation's statutes
   mandate that all software owned by the Foundation should be made
   available under an open source license.

   The chosen license was the GNU General Public License (aka GPL)
   because it was one of most widespread "open source" licenses and it
   would allow integration of many existing code.

   You can find more about the Stichting LogReport Foundation on our
   website. Unfortunately, our articles of association are available in
   Dutch only at this time.
   2.3. 

   If I make a contribution to Lire do I have to put my code under the
   GPL?
   
   The short answer: no. As copyright holder of your contribution, you
   are free to choose whatever license terms please you. Be aware though
   that to be included in Lire, your contribution must be made available
   under terms compatible with the GPL. Examples of licenses that have
   compatible terms are the GNU GPL, the modified BSD license, the X11
   license or the Clarified Artistic License (a list is on
   http://www.gnu.org/licenses/license-list.html).

   The more adequate answer is that it depends of the nature of your
   contribution. Contributions that cannot really be considered
   independent of Lire's distribution and thus have to be considered as
   "derived work" must be distributed under the GPL. This would include
   most patches to Lire's internals or to programs or reports included in
   Lire, but not additions of superservices, services or reports.
   2.4. 

   We want to write a DLF converter for the users of our proprietary
   product, can we distribute it under the same proprietary terms as our
   other products?
   
   Yes. If your DLF converter doesn't include any code from Lire you are
   free to distribute it under the terms of your choice. Note that
   converters that use the publically defined DLF converter API include
   link to developer's documentation, aren't considered to be including
   or copying from Lire's code.

   Remember though that in this case, your DLF converter won't be able to
   be distributed as part of Lire.
   2.5. 

   Can I distribute my XML report specifications under other terms than
   the GPL?
   
   Yes. The Lire Report Specification Markup Language used to define
   those reports is publically defined and no patent is held over it, so
   you are free to choose whatever license terms please you for them.

   Remember though that if your license terms aren't compatible with the
   GPL, your report specifications cannot be included in Lire's
   distribution.
   2.6. 

   I want to reuse your file formats (DLF format, XML report) in my
   project, but I want to release this project under a MIT X-like
   license, may I?
   
   Yes. Those formats aren't protected by any patent so you are free to
   write software that read and write files in those formats if you find
   them convenient for your project.
