Cross-compiling LibreOffice
===========================
The cross-compilation experimentation is going on for four platforms:
Windows, iOS, Android and PowerPC Mac OS X. It happens in the master
branch of LibreOffice. Some people have talked about setting up a
separate branch for Android work, or even separate clones at github,
but that is not necessary.
Cross-compilation of LibreOffice completely is not possible yet. Much
work has been done, "baby steps" for some platforms, much more for
others, but a lot remains. For iOS and Android this work is highly
experimental, originally done in spare time just for the hacking
pleasure. No promise, explicit or implied, is given that it will ever
be finished.
Searching for information about cross-compilation of OpenOffice.org
(the predecessor of LibreOffice) you will find information about what
actually was not cross-compilation, but using QEMU.
Cross-compilation work has been done, to various degrees, for four
platforms: Windows, iOS, Android and PowerPC Mac OS X.
General
-------
In GNU Autoconf terminology, "build" is the platform on which you are
running a build on some software and "host" is the platform on which
running a build of some software and "host" is the platform on which
the software you are building will run. Only in the specific case of
building compilers and other programming tools is the term "target"
used to indicate the platform for which the tools your are building

It seems that with the latest iOS SDK one has to do:
sudo ln -s i686-apple-darwin10 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/usr/include/c++/4.2.1/i686-apple-darwin11
or g++ won't find its headers like <bits/c++config.h>
The --with-system-nss doesn't mean that any Mozilla NSS would be used,
it's just a trick to bypass some tests in the configure script.

From a technical point of view the core Android OS is Linux, but
everything else is different. Unlike iOS, an Android app can use

dynamic linker on the number of libraries you can dlopen. Note that
this is a limitation of user-level code, not the kernel. Here are
various ways around this problem that are being examined.
As for the GUI, the same holds as said above for iOS.
