LibrePilot/make/3rdparty/osgearth

This document describes how to build osg and osgEarth.


Building osgEarth requires:
* osgEarth (http://osgearth.org/)
* OpenSceneGraph (http://www.openscenegraph.org/)
* GDAL (http://www.gdal.org/)
* zlib, png, etc...


Make sure all LibrePilot SDKs are up to date as the osgEarth build relies on them.


More details can be found in osgearth.mk.

Linux prerequisites
----------------------------------

$ sudo apt-get install libzip-dev libpng-dev lipjpeg-dev libtiff5-dev libcurl4-openssl-dev
$ sudo apt-get install  libgeos++-dev libgdal-dev


Alternative (not tested recently but could work):


$ sudo apt-get build-dep openscenegraph


Tested with:


$ curl --version
curl 7.35.0 (i686-pc-linux-gnu) libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3


$ gdal-config --version
1.10.1

OSX prerequisites
----------------------------------

brew install cmake
brew install gdal

Windows prerequisites
----------------------------------

Windows requires many libraries to be build.

See osg_win.sh for more details.


Building
----------------------------------

$ make all_osg


This will:
- clone git repositories in ./3rdparty
- build osg and osgEarth libraries in ./build/3rdparty
- install osg in ./build/3rdparty/install
- create distribution files (tar & md5) in ./build/3rdparty/install
