Self Introduction : Who am I

3
Activities in the Team
Used to be QA Coordinator of OpenOffice.org Japanese
Team (2003-2004)
Join LibreOffice Activities from Sep. 2012
Staff : Mar. 2014 -

I Come from...
I live in Kakamigahara City ( 各務原市 ), Gifu Pref.
City’s name called “Hard to Read It”.
There is Military Airdrome used by JASDF.
(JASDF Gifu Air Base)
Also, there are many aircraft manufacturing companies
e.g. Kawasaki Heavy Industries

Example : Colorful Prototype ships “Viper Zero”

My Hobby
About 20 years of experience in Photography.
12 years passed since I had started to use Digital SLR

8
Introduction : Why we try to build it
As I wrote in the Abstract, Building LibreOffice
yourself is a first step of Development activity.

9
Build makes the software more active
For the Community :
Many persons join their activities e.g. development.
Increase the number of users
For you :
Skill up to use software, with complehending it.
Get skill to finding and fixing bugs.
And experience with new features, new software...

10
Another Reason : Just suitable for you
Recent version (e.g. 5.4.x) uses GTK3
Old version, such as 5.0.x TDF build was not used GTK3
Self Build
TDF Distributed

11
Next step : LibreOffice Online (LOOL), and so on
To build LOOL, building LibreOffice core is needed.
As improving LOOL, It might become much popular.
Advanced : LibreOffice for Mobile Devices
Android version’s source code is integrated.
On mac OS, for iOS will be able to build in the future.

12
On other environments
Shortly I’m going to introduce how to build
LibreOffice on Windows or mac OS.

13
On Windows system
There are some examples introduced in Japanese
Sometime talked on local “Study Parties” of LibreOffice
You need Microsoft’s Account to get VS2013 Community.
To get older versions becomes difficult than before.
And Cygwin is also need to build it.
To setup environment is much harder than others.
The hardest system, maybe.
Finishing setup the environment must be almost finished.

14
On macOS
See TDF Development Wiki.
First, you must install Xcode from App Store.
Using “LODE” environment is the easiest way.
Unfortunately, Current version is not finished cause of building
“firebird” sub block.

15
Linux is the most popular, the easiest...
You have already used it, haven’t you?
Popular distributions are recommended.
openSUSE is one of recommended distribution, of course!!

16
Case 1 : on openSUSE
Tutorial written in TDF wiki will lead you to success
easily on openSUSE.
Complementally how to use “Zypper” for
openSUSE beginners or other distributions users.

17
Read the wiki first
Open wiki.documentfoundation.org/Development/BuildingOnLinux

18
Read the wiki...
Run “Zypper” shown as below :
And cloning source tree, autogen.sh will complete suitable
settings.
Do not forget to install “git”.
% zypper si -d LibreOffice
% git clone git://anongit.freedesktop.org/libreoffice/core core
% zypper in git

19
Is it all, really?
Yes! It is just all procedure
(1) % zypper si -d libreoffice
(2) % ./autogen.sh
(3) % make build
You need only enough time to compile all of the source
I recommend you to sleep while make build
Next morning, you will get new one, probably.

20
If OS installation is not “Completed”.
“Incomplete install” may lead you to troubles
I had encountered the trouble without Gnome/KDE.
I want to use “Cinnamon” first...
Zypper will help you to install libraries needed.
For users not use openSUSE usually ;
Its option “search” (shorten “se”) shows package name
And it shows also already installed or not yet.

21
Example : “zypper search”
./autogen.sh is stoped not installed cups library.
% ./autogen.sh
....(snip)----
configure: error: Could not find CUPS. Install libcups2-dev or cups-devel
Error running configure at ./autogen.sh lin 293.
% zypper se cups-devel
S | Name | Summary | Type
--+--------------------+----------------------------------+--------
| cups-devel | Development Environment for CUPS | package
| libgnomecups-devel | GNOME CUPS library | package

22
In case of Ubuntu etc.
This procedure is important on next case.

23
In case of Ubuntu etc.
This procedure is important on next case.

24
I think it may be strange…! ?
On openSUSE, we can use zypper both as installation
command, package search command, etc.
We use on Debian or Ubuntu, “apt-get” as an installation tool.
What is package search command on their systems?
Use “apt-cache” as package search command.
Installation and Search commands have each different
command name. It may be difficult for beginners, I think.

25
Case 2 : on Linux Mint
The Case of “Does not run dependency Script”.
Install some libraries manually, and you can get
more experience and interest about the software.

26
Cinnamon / Mate may cause troubles to setup
Build dependency correction procedure does not work
Similar trouble on openSUSE caused when I ignored to
install Gnome/KDE environment.
Linux Mint :
Based on Ubuntu (there’s also Debian based one)
Cinnamon, or Mate is standard desktop environment
You can also choose KDE, Xfce version
How to solve :
Install libraries manually, in each time when autogen.sh
stopped.

27
What is the advantage to know that case
You can know what library needed by configure script.
You can advise preciously when other beginners encounter
their similar trouble.
“Rubber-Stump” experiences don’t make you better
I’m going to show the procedure step by step.

28
(Cinnamon version only) : There is not “aclocal”
“aclocal” has dependency between with autotool
You must “autotools-dev” first, and you can install “automake”
include “aclocal”.
Mate version has “aclocal”, you will encounter this trouble on
Cinnamon version only.
$ sudo apt-get install autotools-dev
$ sudo apt-get install automake

29
Run autogen.sh again and again...
Script’s stops show you what library insufficient.
- libcups2-dev
- libfontconfig1-dev
Library’s names are ase able to search with Web or apt-
cache.
$ sudo apt-get install libcups2-dev
$ sudo apt-get install libfontconfig1-dev

30
C++ compiler is not installed
You can use gcc, but some environment is not installed g++
at the first time.
Install It.
$ sudo apt-get install g++

31
OpenJDK is recommended
Of course you can install Oracle JDK
You must add PPA repository to install it.
You can also choose option “--without-java”.
I recommend to install OpenJDK
$ sudo apt-get install openjdk-8-jdk

32
Insufficient libraries / binaries (1)
28 libraries / binaries to complete autogen.sh
I’m going to show below and next page.
- gperf
- doxygen
- libxslt1-dev
- xsltproc
- libxml2-utils
- python3-dev
- python-dev
$ sudo apt-get install gperf
$ sudo apt-get install doxygen
...(snip)...

33
Kerberos library is needed (from 16.4)
Linux Mint 18.x are based Ubuntu 16.4 or 17.4 (current)
Libraries for Kerberos is needed.
This note was vanished in TDF wiki
But it remains in Japanese translated wiki.
We need two packages shown below:
- comerr-dev
- libkrb5-dev
$ sudo apt-get install comerr-dev
$ sudo apt-get install libkrb5-dev

34
Insufficient libraries / binaries (2)
Continue from the previous page.
- libx11-dev
- libxt-dev
- libxext-dev
- libxrender-dev
- libxrandr-dev
- libgtk-3-dev
- libdbus-glib-1-dev
- libgtk2.0-dev
$ sudo apt-get install libx11-dev
$ sudo apt-get install libxt-dev
...(snip)...

35
This is the rest 3 packages to finish script
OpenGL and build tool, test tool.
- libglew-dev
- ant
- junit4
$ sudo apt-get install libglew-dev
$ sudo apt-get install ant
$ sudo apt-get install junit4

36
Script was finished, but build will fail
You need one additional package to build LibreOffice
Script’s warning also resolve.
- nasm
- libgcrypt11-dev
$ sudo apt-get install nasm
$ sudo apt-get install libgcrypt11-dev

37
Tips building on Linux Mint
You can finish script with installation packages manually.
I recommend write what package needed

38
Conclusion
One night of experience will change your life.
Enjoy it!

39
Continue better habits for your life
You need only enough time to build it.
Only a few hours with current machines.
I’m sorry about Arm architectures, evaluation board, etc.
You must get “good sleep” for your health.
