Building 2.x (680er/300er series) under Windows with 4NT

This document describes the requirements and actions that you need to build on Windows.

Commands you have to type on the keyboard follow this syntax throughout this document:

D:\my\source> winenv.bat

In this example, the script winenv.bat is executed in the directory D:\my\source under a 4NT shell. Unless stated otherwise, all commands appearing in this document should be entered from a 4NT shell (the exception is the configure script which has to be run from a cygwin bash shell). $SRC_ROOT will denote the directory in which the source code of is stored.

Table of Contents


This section is meant as a reminder or checklist for those who have some experience in building Everybody else should jump to the Build Requirements section.

Even experienced builders are well advised to check the release notes at and the section Build Requirements in this document to inform yourself about changes since the previous releases.

Detailed step-by-step build descriptions are given from the next section on.

Overview of Performing a Full Build

To perform a full build, you need to follow these steps:

  1. Get the source code, either from the download webpage ( or alternatively via a check-out from the cvs tree against a release tag, e.g. OpenOffice_3_1_0.
  2. Run the configure script in a cygwin bash shell to check all requirements and to create the script winenv.bat.
  3. Run the winenv.bat (under 4NT) script to set all environment variables.

    Please see the last screen from the configure script for more specific information on setting up for your platform.

  4. Build typing dmake in $SRC_ROOT, or build --all in the instetoo_native module, or build followed by deliver in the individual modules.
For detailed build instructions, see the section Building a Full Build of the Office Suite in this document. The installation procedure is described at the end of this document.

Build Requirements

Before you start building, you must ensure that your system satisfies the recommended software and hardware requirements for the type of system you are working on. For Windows, these are as follows:

see Windows Build Requirements

Get the source code

You have two options to get the source code:

Generating the Build Environment and Build Tools

Ideally, in keeping with the principles of open source, you would use an open source shell to build on a computer running a Win32 operating system. However, you decided to use a non-open source shell to build on a computer running a Win32 operating system: the 4NT command shell.

On the other hand, the bash shell from the cygwin tools is needed to run the configure script which generates the build environment. The configure script checks that all software, hardware, and system requirements for the build are satisfied, and it creates a configuration file called winenv.bat that sets all necessary build environment variables and builds the dmake.exe. See the example below.

This configuration file is created in the SRC_ROOT directory. A top-level makefile script are moved into SRC_ROOT as well. This is due to technical reasons: The SRC_ROOT directory in the cvs tree can only hold directories. On the other hand, the top-level should logically be placed in the top-level directory SRC_ROOT. The cvs tree holds these files in config_office and configure copies them up.

The following should demonstrate in detail what steps have to be done to set up the environment:

As 4nt is not the only possible shell, you have to enable the use of 4NT with --with-use-shell=4nt You should exit the bash shell. Now you can run the environment settings file winenv.bat from your 4NT shell.

Note the change in pathname notation. Since the cygwin bash shell won't accept backslashes, paths have to be typed in a cygwin bash notation which is /cygdrive/c/path/to/file, instead of C:\path\to\file. This may appear confusing at the moment, but sticking to this notation will work.

There are a number of further options that you can use with the configure script. To display these options, type the following command:

config_office> bash configure --help

After running configure you have to execute the configuration file which sets all environment variables. The generated file is called winenv.bat.

If you experiment with the newest sources from the cvs-tree, mind that updates to the configure process may not happen via updates of configure (the script file) but via the files and The configure script itself is created from using the autoreconf command. The perl script set_soenv is created when you run configure from

If you need to modify or create a correct configure you would run commands like the following:

$SRC_ROOT> cd config_office
config_office> cvs update
get a bash shell
config_office>bash autoconf
exit the bash shell
To update the configure script. If you only use code from the snapshot releases on the web, you don't need to be concerned about this.

Build Instructions

Building a Full Build of the Office Suite

Now you are ready to build To build the entire suite, all you have to do (after having created the environment as described above) is to run dmake from the top-level directory. This may take several hours.
$SRC_ROOT> dmake

If you wish to control the build more you can perform a build with local install sets or tarballs.

	cd instetoo_native
	build --all

If you decide to rebuild a module or build each module individually (mind dependencies!), you will have to use the build tool. A subsequent deliver will copy all created binaries, libraries etc. into the solver tree:

$SRC_ROOT/(module)> build
$SRC_ROOT/(module)> deliver

The following table shows the time required to build on a system with a particular specification. You can use these details to estimate the time required to build on your system.

Architecture Intel
Processor Athlon XP1700
Processor speed 1466 MHz
RAM 512 MB
Hard Disk 160 GB 7200 RPM IDE
Time (for SRC680_m86) ~17 h

Building a Project with Debug Information

To rebuild a complete project with debug information, remove all object files by removing the directory. Then run build with the debug option set to true:

$SRC_ROOT/(module)> rm -rf
$SRC_ROOT/(module)> build debug=true

Instructions to Build an Installation Set

The build process (started with a top-level dmake or build --all in $SRC_ROOT/instsetoo_native) will create an installation sets in English. A simple build in $SRC_ROOT/instsetoo_native will also create the installation sets, provided all other modules are already built.

If you have built an installation set earlier and want to re-build it, please delete the local outpath first:

$SRC_ROOT/instsetoo_native> rm -rf

The English installation set will be located at $SRC_ROOT/instsetoo_native/ Execute the setup binary to install:

$SRC_ROOT> cd instsetoo_native/
en-US> setup.exe
The en-US in the path names indicates that the localization is American English. This value corresponds to the language tags defined by RFC 1766 (Tags for the Identification of Languages). The German installation set will be located in a de subdirectory. This scheme holds true for all localizations you may have chosen explicitly (see next section Building Localized Versions of

For a network installation, use the -net option to setup. Details on the network installation process can be found at in the installation project webpage.

For information on creating an automated installation script and create a response file.

Building Localized Versions of

Running the configure script with the --with-lang option will introduce the build of additional language resources. This switch accepts one or more RFC 1766 language tags as arguments, unfortunately not all languages are supported. Check the value of the completelangiso macro in $SRC_ROOT/solenv/inc/ for all the currently supported language tags.

Example: --with-lang="de fr" enables the build of the localized german and french version.

The environment variable WITH_LANG will then contain the language tags of the additional (en-US will always be build) languages.

Building Localized Language Packs

If you build additional localized languages it is possible to generate Language Packs that contain only the changes needed to add the additional language to an of a different language.

The following commands will generate language packs languages that were specified with the --with-lang switch during the configure phase. Note that you can only build the language packs after you have build the complete office with all selected languages.

$SRC_ROOT> cd instsetoo_native/util; dmake ooolanguagepack
