The LibreOffice 7.4 SDK comes with
a set of development tools, base libraries, header
files and helper class files that can be used to
develop Java/C++ components, to embed the
LibreOffice 7.4 application in your
own programs, or to use the API (scripting or
remote control the office). For a complete working
environment, we have some additional
requirements:
|
| LibreOffice 7.4
installation |
The SDK works on top of an
existing LibreOffice installation and uses the same
libraries as the LibreOffice installation.
Download the SDK from the same
source as your LibreOffice packages.
- If you have installed an official The
Document Foundation LibreOffice release,
download and install the corresponding SDK
release for your platform from
https://www.libreoffice.org/download
- If you have installed a downstream LibreOffice
release via your operating system's package
management tools, use the same package
management tools to install the corresponding
downstream SDK package(s).
Note: Do not mix and match The Document
Foundation LibreOffice releases with downstream
SDK packages or vice versa! |
 |
| JDK (1.5 or higher) |
A JDK is necessary for developing Java components
or applications. An appropriate Java SDK can be
found on
http://java.sun.com/products.
Recommendation is to use Java 7 or later for
64bit, and Java 6 for 32bit.
Note: The Java compiler is
optional! |
|
| C++ compiler |
A C++ compiler is necessary for
developing C++ components or applications. UNO
depends on a compiler dependent language binding, so
that we use the appropriate compiler where a
language binding exists:
| Linux |
GNU C++ compiler, gcc version
4.1 or later |
| macOS |
Xcode |
| Windows |
Microsoft C++ Compiler,
Microsoft Visual Studio 2010 or later, or the
Express edition thereof |
Note: The C++ compiler is
optional! If you use the Express
edition you have to ensure that the
Microsoft Visual Studio 2008 Redistributable Package
is also installed. You can download this package
from Microsoft directly. |
|
| Microsoft .NET Framework SDK version 1.0 or
higher |
The SDK is required for building
CLI applications. That is, programs written in
languages, such as C# or VB.NET.
Note: The .NET Framework is
optional! |
|
| GNU make (3.79.1 or higher) |
GNU make is used to build the examples of the
SDK. GNU make is available from
http://www.gnu.org.
It can be ftped via
ftp://ftp.gnu.org/gnu/make
Note: Windows user can find an executable
of gnu make under
http://www.mingw.org/wiki/Getting_Started
(see the mingw32-make link under "Manual
Installation"). Do not use the Cygwin make,
because it does not work well. On Solaris gnu make
can be found often under
/usr/sfw/bin/gmake, but keep in mind
that you have to use 'gmake' then. Or you
can find gnu make also under
http://www.sunfreeware.com/. |
|
| zip tool (2.3 or higher) |
The zip tool is used to create
UNO packages. zip is a new requirement to make the
SDK independent of a Java SDK.
If you do not have these already, you can download
them from
http://www.info-zip.org.
Note: The cygwin zip.exe does not work for the build
under the 4NT shell. You have to use the native w32
version. |
|
| cat and sed tools |
The cat and set tools are used
to create some extensions.
Note for Windows users: If you do not have
these already, you can download them from
http://sourceforge.net/projects/unxutils/files/latest/download.

|
The SDK provides a
mechanism which configures the SDK build
environment to your personal needs the first time
you use the SDK environment. This configuration
step creates a new setsdkenv_XXX script in the
user's home directory:
- $HOME/$OO_SDK_NAME/setsdkenv_unix.sh ->
for Unix-like systems
- C:\Documents and Settings\<username>\Application Data\%OO_SDK_NAME%\setsdkenv_windows.bat ->
for Windows
To start the configure script, change into the SDK root directory and
run:
- ./setsdkenv_unix ->
for Unix-like systems
- setsdkenv_windows.bat ->
for Windows
The configure script
requests relevant information
and directories (SDK, LibreOffice, GNU make, Java,
C++), in order to prepare a working SDK
environment. (On Unix-like systems, the configure script recursively
starts a new interactive shell with the relevant environment variables
set; this is not needed on Windows.)
After completing the configure script
once, the newly created script is always used to
set the necessary environment variables for using
the SDK and the required tools.
On Unix-like systems, the configure script
uses Perl. Linux systems should have installed a
working Perl version, and on Solaris you can find
a working Perl version under
http://www.sunfreeware.com/
if necessary. On Windows, the configure script
uses Windows Script and a JScript. If you have
problems with Windows Script, you can download a
newer version of
Windows Script.
If you use the template batch file, edit and set
the following variables:
| OFFICE_HOME |
Path to an existing
LibreOffice installation, e.g.
"/opt/libreoffice8". |
| OO_SDK_NAME |
The configuration uses the
directory name of the SDK, but you can use
another name as well. It is important that the
name does not contain spaces, because of a
limitation of gnu make which cannot handle
spaces correctly. This name is, for example,
used to create an output directory in the
users home directory for any generated output
when you use the SDK build environment. |
| OO_SDK_HOME |
Path to the SDK root
directory, e.g.
"/opt/libreoffice/sdk" |
| OO_SDK_JAVA_HOME |
Path to a JDK root directory.
The JDK is optional and only necessary
if you like to run the Java examples or if you
like to use the SDK environment to develop
your own Java solution. |
| OO_SDK_CPP_HOME |
Path to the C++ compiler (on
Windows, the directory where the
"vcvar32.bat" file can be
found). The C++ compiler is optional
and only necessary for building the C++
examples. |
| OO_SDK_CLI_HOME |
Path to the C# compiler and
VB.NET compiler (on Windows, this directory
can be found under the system directory (e.g.
c:\WINXP\Microsoft.NET\Framework\v1.0.3705).
The compilers are optional and only
necessary for building the CLI examples.
Note: Windows only! |
| OO_SDK_MAKE_HOME |
Path to GNU make. |
| OO_SDK_ZIP_HOME |
Path to the 'zip' tool. |
| OO_SDK_CAT_HOME |
Path to the 'cat' tool. |
| OO_SDK_SED_HOME |
Path to the 'sed' tool. |
| OO_SDK_OUTPUT_DIR |
Path to an existing directory
where the example output is generated. The
output directory is optional, by
default the output is generated in the SDK
directory itself. If an output directory is
specified, the output is generated in an SDK
dependent subdirectory in this directory (e.g.
<OO_SDK_OUTPUT_DIR> /LibreOffice
7.4/LINUXExample.out) |
| SDK_AUTO_DEPLOYMENT |
If this variable is set, the
component examples are automatically deployed
into the LibreOffice installation referenced
by OFFICE_HOME. See also section
"Extension Manager - unopkg"
from the Developer's Guide. |
You must run the setsdkenv_XXX script
every time you want to use the configured SDK
environment. The settings are local for the
current shell on Windows or the new started shell
on Unix-like systems. On Unix-like systems you can now source the prepared
environment script file
("setsdkenv_unix.sh") to prepare your
current shell instead of starting a new shell.

Manual Setting
If you do not want to use the script to set your
working environment, you must set the appropriate
environment variables yourself. The script sets
the following environment variables:
Common Environment Variables
| OO_SDK_NAME |
See description
above. |
| OO_SDK_URE_BIN_DIR |
The path within the chosen
LibreOffice URE installation where binary
executables are located. |
| OO_SDK_URE_LIB_DIR |
The path within the chosen
LibreOffice URE installation where dynamic
libraries are located. |
| OO_SDK_URE_JAVA_DIR |
The path within the chosen
LibreOffice URE installation where Java JARs
are located. |
| CLASSPATH |
=$OO_SDK_URE_JAVA_DIR/libreoffice.jar;
$OO_SDK_URE_JAVA_DIR/unoloader.jar;
$CLASSPATH
The classpath will be set or extended to
the necessary jar files of the specified
LibreOffice installation.
|
| OFFICE_PROGRAM_PATH |
=$OFFICE_HOME/program
This variable is used to find, for example,
the office type library and the UNO package
deployment tool.
|
| UNO_PATH |
=$OFFICE_PROGRAM_PATH
This variable is used to ensure that the
new C++ UNO bootstrap mechanism uses the
configured LibreOffice installation of the
SDK. Normally the bootstrap mechanism finds
the default office installation for the user
on the system. This variable is optional but
is set from the scripts to ensure a
homogeneous environment. Especially useful
during development where you might have more
than one office installation installed.
|
Environment Variables for Unix-like systems
Solaris
| LD_LIBRARY_PATH |
=$OO_SDK_URE_LIB_DIR:
$OO_SDK_HOME/(solsparc|solintel)/lib:
$LD_LIBRARY_PATH
The LD_LIBRARY_PATH will be set or will be
extended by the office/URE library path, the
platform dependent lib directory for several
additional libraries.
|
| PATH |
=$OO_SDK_HOME/(solsparc|solintel)/bin:$OO_SDK_MAKE_HOME:
$OO_SDK_ZIP_HOME: [$OO_SDK_CPP_HOME:]
[$OO_SDK_JAVA_HOME/bin:]
$OO_SDK_URE_BIN_DIR: $PATH
The PATH variable will be extended by the
paths for the SDK development tools, the
compiler, the JDK, GNU make, the zip tool
and the OO_SDK_URE_BIN_DIR, where the
compiler or the JDK are optional.
|
| The script
additionally creates symbolic links to the
public dynamic libraries of the URE in
$OO_SDK_HOME/(solsparc|solintel)/lib,
which are needed for linking. |
Linux
| LD_LIBRARY_PATH |
=$OO_SDK_URE_LIB_DIR:
$SDK_HOME/linux/lib:
$LD_LIBRARY_PATH
The LD_LIBRARY_PATH will be set or will be
extended by the office/URE library path, the
platform dependent lib directory for some
additional libraries.
|
| PATH |
=$OO_SDK_HOME/linux/bin:$OO_SDK_MAKE_HOME:
$OO_SDK_ZIP_HOME: [$OO_SDK_CPP_HOME:]
[$OO_SDK_JAVA_HOME/bin:]
$OO_SDK_URE_BIN_DIR: $PATH
The PATH variable will be extended by the
paths for the SDK development tools, the
compiler, the JDK, GNU make, the zip tool
and the OO_SDK_URE_BIN_DIR, where the
compiler and the JDK are optional.
|
| The script
additionally creates symbolic links to the
public dynamic libraries of the URE in
$OO_SDK_HOME/linux/lib, which are
needed for linking. |
Environment Variables for Windows
| PATH |
=%OO_SDK_HOME%\windows\bin;
%OO_SDK_MAKE_HOME%; %OO_SDK_ZIP_HOME%;
[%OO_SDK_CLI_HOME%;] [%OO_SDK_CPP_HOME%;]
[%OO_SDK_JAVA_HOME%\bin;]
%OO_SDK_URE_BIN_DIR%; %PATH%
The PATH variable will be extended by the
paths for the SDK development tools, the
compiler, the JDK, GNU make, the zip tool
and the OO_SDK_URE_BIN_DIR.
|
| LIB |
=%OO_SDK_HOME%\windows\lib;
%LIB%
The LIB variable will be extended by the
path to the import libraries that are
necessary for Windows.
|
| In addition to
setting these environment variables, the
script calls the
"vcvar32.bat" batch file
which is provided by the Microsoft Developer
Studio to set the necessary environment
variables for the compiler. |
