Manual setup for all systems

Configuring xsltproc
Configuring local DocBook XSL and DTD distributions
Configuring Doxygen for Documentation Extraction
Configuring Apache FOP

This section describes how to manually configure Boost Boost version 2 (BBv@) for BoostBook. If you can use the automatic setup script, you should. All configuration will happen in the BBv2 user configuration file, user-config.jam. If you do not have a copy of this file in your home directory, you should copy the one that resides in tools/build/v2 to your home directory. Alternatively, you can edit tools/build/v2/user-config.jam directly or a site-wide site-config.jam file.

Configuring xsltproc

To configure xsltproc manually, you will need to add a directive to user-config.jam telling it where to find xsltproc. If the program is in your path, just add the following line to user-config.jam:

using xsltproc ;

If xsltproc is somewhere else, use this directive, where XSLTPROC is the full pathname to xsltproc (including xsltproc):

using xsltproc : XSLTPROC ;

Configuring local DocBook XSL and DTD distributions

This section describes how to configure Boost.Build to use local copies of the DocBook DTD and XSL stylesheets to improve processing time. You will first need to download two packages:

  • Norman Walsh's DocBook XSL stylesheets, available at the DocBook sourceforge site. Extract the DocBook XSL stylesheets to a directory on your hard disk (which we'll refer to as the DOCBOOK_XSL_DIR).

  • The DocBook DTD, available as a ZIP archive at the OASIS DocBook site. The package is called "DocBook XML 4.2". Extract the DocBook DTD to a directory on your hard disk (which we'll refer to as the DOCBOOK_DTD_DIR). You will want to extract this archive in a subdirectory!

Add the following directive telling BBv2 where to find the DocBook DTD and XSL stylesheets:

#  BoostBook configuration
using boostbook 
  : DOCBOOK_XSL_DIR
  : DOCBOOK_DTD_DIR
  ;

Whenever you change this directive, you will need to remove the bin.v2 directory that BBv2 generates. This is due to longstanding bug we are trying to fix.

At this point, you should be able to build HTML documentation for libraries that do not require Doxygen. To test this, change into the directory $BOOST_ROOT/libs/function/doc and run the command bjam --v2: it should produce HTML documentation for the Boost.Function library in the html subdirectory.

Configuring Doxygen for Documentation Extraction

Doxygen is required to build the documentation for several Boost libraries. You will need a recent version of Doxygen (most of the 1.3.x and 1.4.x versions will suffice). BBv2 by adding the following directive to user-config.jam:

using doxygen : DOXYGEN ;

DOXYGEN should be replaced with the name of the doxygen executable (with full path name). If the right doxygen executable can be found via the path, this parameter can be omitted, e.g.

using doxygen ;

Important

The relative order of declarations in user-config.jam / site-config.jam files is significant. In particular, the using doxygen line should come after the using boostbook declaration.

Configuring Apache FOP

In order to generate PDF and PostScript output using Apache FOP, you will need a Java interpreter and Apache FOP (version 0.20.5 is best). Unpack Apache FOP to some directory. The top level directory of the FOP tool should contain a main script called fop.sh on Unix and fop.bat on Windows. You need to specify the location of that script and Java location to Boost.Build. Add the following to your user-config.jam or site-config.jam:

using fop : FOP_COMMAND 
          : JAVA_HOME 
          ;

replacing FOP_COMMAND with the full path to the FOP main script, and replacing JAVA_HOME with the directory where Java is installed. If the JAVA_HOME environment variable is already set, you don't need to specify it above.

To test PDF generation, switch to the directory $BOOST_ROOT/libs/function/doc and execute the command bjam --v2 pdf. In the absence of any errors, Apache FOP will be executed to transform the XSL:FO output of DocBook into a PDF file.
