These repository give you an updated gdal version and a development version of qgis too (apt-get install qgis)

Install some depenndecies:

{{{
 
apt-get install libqt4-core libqt4-dev libqt4-gui libqt4-qt3support lsb-qt4 qt4-dev-tools qt4-doc qt4-qtconfig \
uim-qt gdal-bin libgdal1-dev libgeos-dev proj libgdal-doc libtiff4-dev subversion make g++ g++-4.1 gcc libgeotiff1.2 \
libgeotiff-dev libgeotiff-epsg cmake
 
}}}

Download and compile Openscenegraph from source :

{{{
svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.6.1 OpenSceneGraph
cd OpensceneGraph
mkdir build
cd build
ccmake .. # delete the not-find libraries from the cmake setting-lines
# press c to configure
# press g to generate makefile
make
sudo make install
}}}

Download and install ffmpeg (maybe the repository version of ffmpeg can be used too ... i'll check it) :

{{{
cd /home/sasha/GIS
mkdir DEP
cd DEP
svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
cd ffmpeg
./configure --disable-vhook --disable-mmx --disable-static --enable-shared
make
cd libswscale
make
sudo make install
cd ..
sudo make install

Download ossim from svn and compile it:

{{{
cd
mkdir -p GIS/ossim
cd /GIS/ossim
svn co https://svn.osgeo.org/ossim/trunk .

# Set the ossim environment variables :

echo "export OSSIM_DEV_HOME=/home/sasha/GIS/ossim" >> /home/sasha/.bashrc
echo "export OSSIM_HOME=/home/sasha/GIS/ossim/ossim" >> /home/sasha/.bashrc
echo "export OSSIM_QT_HOME=/home/sasha/GIS/ossim/ossim_qt" >> /home/sasha/.bashrc

echo "export OSSIM_INC_DIR=/home/sasha/GIS/ossim/ossim/include" >> /home/sasha/.bashrc
}}}

Add /usr/local/lib and /usr/local/lib64 (if you're on 64 bit machine) to you're /etc/ld.so.conf.d/:
 
{{{
sudo touch /etc/ld.so.conf.d/local.conf
sudo echo "/usr/local/lib" >> /etc/ld.so.conf.d/ossim.conf
sudo echo "/usr/local/lib64" >> /etc/ld.so.conf.d/ossim.conf
}}}

Compile Ossim core libs:

{{{
cd /home/sasha/GIS/ossim/ossim
 ./configure --with-geotiff=/usr/include/geotiff --prefix=/usr --with-jpeg=/usr --with-libtif
make
sudo make install
}}}

To build libwms on ubuntu 8.10 download these patch :

[http://www.geofemengineering.it/libwms.patch libwms_patch]

save the patch as libwms.patch and run : 

{{{ 
cd /home/sasha/GIS/ossim/libwms
patch -Np0 < /path/to/libwms.patch 
make
sudo make install
}}} 
 
 
To load the new libraries open a new terminal and type :

{{{
sudo ldconfig
cd /home/sasha/GIS/ossim/ossim_qt4
qmake ossim_qt4.pro
make
sudo make install
}}} 

Build ossimPredator libs:
{{{
cd /home/sasha/GIS/ossim/ossimPredator
mkdir lib
cd src
make
sudo -s
sudo OSSIM_DEV_HOME=$OSSIM_DEV_HOME OSSIM_HOME=$OSSIM_HOME make install
}}} 


Now build ossimplanet, fon ubuntu 8.10 download these patch:

[http://www.geofemengineering.it/ossimPlanet.patch ossim_planet_patch]

Save the patch as ossimPlanet.patch and run :

{{{
patch -Np0 < /path/to/ossim_planet.patch
OSSIMPREDATOR_LIB_DIR=/usr/local/lib make
sudo OSSIMPREDATOR_LIB_DIR=/usr/local/lib make install
cd /home/sasha/GIS/ossim/ossimPlanetQt/
qmake ossimPlanetQt.pro
make
sudo make install
sudo ldconfig
}}} 


To buid ossom_plugin, change the gdal setting in the file

/home/sasha/GIS/ossim/ossim_plugins/make.opt.in
/home/sasha/GIS/ossim/ossim_plugins/make.opt

To point where you have gdal's files (hhere i used gdal from the repository)
  
{{{
GDAL_HOME =/usr/
ifeq ($(origin GDAL_HOME), undefined)
    GDAL_INCLUDES =/usr/include/gdal/
    GDAL_LIBS =/usr/lib -lgdal
else 
    GDAL_INCLUDES = -I$(GDAL_HOME)/include/gdal/
    GDAL_LIBS = -L$(GDAL_HOME)/lib -lgdal
endif
}}}

{{{
cd /home/sasha/GIS/ossim/ossim_plugins/
make
}}}

Create a "data" directory readed from ossim at its sturtup and copy iside it the "ossim support data":
{{{
mkdir /home/sasha/.ossim
cp -r /home/sasha/GIS/ossim/ossim_package_support/fonts /home/sasha/.ossim/fonts
cp -r /home/sasha/GIS/ossim/ossim_package_support/geoids /home/sasha/.ossim/geoids
cp -r /home/sasha/GIS/ossim/ossim_package_support/images /home/sasha/.ossim/images
}}}
