# Compiling latest GRASS source code on a 64-bit machine (with an ATI graphic card) under Ubuntu 7.10 64-bit with support for:
# 64-bit, SQLite, OpenGL, PYTHON, FFMPEG
#
# Based on script for Ubuntu 7.06 by David 

# Assuming it is the first time installing SVN, PROJ, GDAL/OGR



*** PREPARATION ***

sudo apt-get update && sudo apt-get upgrade


# installing SVN

sudo apt-get install subversion


# installing dependencies for compiling (in general)
# and dependencies for GRASS: PROJ, GDAL/OGR

sudo apt-get install grass build-essential flex bison libncurses5-dev zlib1g-dev \
    libjpeg62-dev libgdal1-dev libtiff4-dev ligcc++ bpng12-dev tcl8.4-dev tk8.4-dev fftw-dev \
	libfreetype6-dev libavcodec-dev libxmu-dev gdal-bin libreadline5 libreadline5-dev \
	make


# installing SQLite

sudo apt-get install sqlite3 libsqlite3-dev


# download latest source code from GRASS SVN repository

svn checkout https://svn.osgeo.org/grass/grass/trunk grass_trunk
  
# in case of a subsequent update: use the command "svn up" (without quotes)



# before attempting to compile GRASS
# READ section (C) in the INSTALL file located in the main directory of GRASS source code
# entitled: (C) COMPILATION NOTES for 64bit platforms" section



*** FFTW ***

# installing FFTW3 if not already on system

sudo apt-get install fftw3 fftw3-dev

# not sure if the "-dev" is realy necessary!



*** FFMPEG ***

# from: http://stream0.org/2008/01/install-ffmpeg-on-ubuntu-gutsy.html

# checkout svn source code

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg


# install dependencies

sudo apt-get install liblame-dev libfaad2-dev libfaac-dev libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev libdts-dev checkinstall build-essential subversion


# guide to ffmpeg directory

cd ffmpeg


# if necessary "make distclean" (without quotes)

./configure --enable-gpl --enable-pp --enable-libvorbis --enable-libtheora --enable-liba52 --enable-libdc1394 --enable-libgsm --enable-libmp3lame --enable-libfaad --enable-libfaac --enable-libxvid --enable-pthreads --enable-libx264 --enable-shared


# compilation

make


# installation on /usr/local/bin -- important to know when configuring GRASS' source code for compilation

sudo checkinstall


* go for GRASS!

cd /to/wherever/your/GRASS/source/code/is


# configuration

CFLAGS="-g -Wall" LDFLAGS="-s" ./configure     --enable-64bit     --with-libs=/usr/lib64     --with-cxx     --with-freetype=yes     --with-postgres=no     --with-sqlite=yes     --enable-largefile=yes     --with-tcltk-includes=/usr/include/tcl8.4     --with-freetype-includes=/usr/include/freetype2     --with-opengl-libs=/usr/include/GL     --with-readline --with-python=yes --with-ffmpeg=yes --with-ffmpeg-includes=/usr/local/include/ffmpeg


# if OpenGL fails then maybe it is necessary to link glxATI.h with glx.h and re-run configuration

# (1) cd /usr/include/GL
# (2) sudo ln glxATI.h glx.h
# (3) back to "configuration"


# compilation

make


# compilation is expected to end with a "no errors statement":

# Started compilation: Wed Feb 27 00:24:36 CET 2008
# --
# Errors in:
# No errors detected.


# installation

sudo make install


# launch 64-bit GRASS.6.3.sv

grass63



*** NOTES ***

# in case of errors in future compilation attempts, remember to remove program binaries with

make clean

# and the files created with the "configuration" from previous compilations with

make distclean
