Improvement: reduce LibreOffice to its minimum for Online use about officeonlin-install.sh HOT 14 CLOSED

I have been testing disabling different functionality with compiling and this is what i came up with. With-system-XXXX options gave varying results so I left them out. Compile with 3 cpu was done in less than 2 hours.

--without-help
--without-myspell-dicts
--without-java
--without-doxygen
--disable-cups
--disable-dconf
--disable-odk
--without-junit
--disable-dbus
--disable-firebird-sdbc
--disable-postgresql-sdbc
--disable-gltf
--disable-extensions
--disable-pdfimport
--disable-neon

from officeonlin-install.sh.

Totally agree.

My suggestions:

At first look there is some safe options to disable features not needed by headless service:

• --disable-avmedia
• --disable-database-connectivity
• --disable-lpsolve
• --disable-coinmp
• --disable-gtk
• --disable-gtk3
• --disable-systray
• --disable-dbus
• --disable-gui
• --disable-randr
• --disable-gstreamer-1-0
• --without-helppack-integration

And enable some optimizations (may build longer):

• --enable-lto
• --enable-eot
• --enable-release-build
• --with-system-bzip2
• --with-system-zlib
• --with-system-jpeg
• --with-system-expat
• --with-system-libxml
• --with-system-icu
• --with-system-poppler
• --with-system-curl
• --with-system-boost
• --with-system-libpng
• --with-alloc=jemalloc (need libjemalloc-dev)

There is may be more options. Can look into Ubuntu/Debian LibreOffice source package.

from officeonlin-install.sh.

Questionable options:

• --enable-python=no - do LooL need python?
• --disable-neon - do we need webdav here?
• --disable-cups - do we need printing here?
• --disable-gltf --disable-collada - need some 3d modeling import?
• --enable-introspection=no - not sure about this
• --disable-pdfimport - how often people import pdf into Draw?
• --disable-odk - ODK probably not needed
• --disable-extension-update - this probably not needed too
• --without-java - JAVA probably not needed

from officeonlin-install.sh.

So, not all go well.
I'll update working set of options soon.

from officeonlin-install.sh.

Thank you @Sergey, 👍
Do you know if it possible to build only some modules instead of all the project ? Like core, writer, table and draw ?

from officeonlin-install.sh.

I think not.
It's even not possible build LiO without GUI, OpenGL, DB drivers, other strange stuff.

At least we can reduce build time by using some system libraries.
And disable python, java, and small amount of other stuff.

from officeonlin-install.sh.

OK Thanks
I supposed it could be possible while reading the LiO's github Readme for they took the time to writes about what module are importants.
maybe we need to simply run the "make" from inside the module's folder... 😕

from officeonlin-install.sh.

Once I was tried to build python-uno separately. No luck.

from officeonlin-install.sh.

And something strange happens with systemd unit:

• loolwsd can't make forks after some time,
• systemd looses cgroup it maked for loolwsd

May be it's because I using OpenVZ + 2.6.32 (Proxmox 3.4). It may have no complete support for cgroups.
I'll try KVM with fresh Debian 8.7 soon.

from officeonlin-install.sh.

Some more options to disable.
--disable-lpsolve
--disable-coinmp
--disable-systray
--disable-randr
--disable-gstreamer-1-0
--without-helppack-integration
--disable-report-builder
--disable-coinmp
--disable-pdfium
--disable-collada

from officeonlin-install.sh.

Very nice idea.
Where exactly do I have to put these params?
In the 'lo_configure_opts' var?

from officeonlin-install.sh.

I have created a pull request so it is already in the script.
#106

from officeonlin-install.sh.

Very nice. Thanks. Without knowing it, I downloaded the last version just after your pull.

from officeonlin-install.sh.

update:
I've been using the options found in this file : https://github.com/LibreOffice/online/blob/distro/collabora/collabora-online-3-0/docker/l10n-docker-nightly.sh for Libreoffice build (except the disable cups) and result have been quite goods building from scratch.
I'll look for pushing them as default.
