Ok, Mathieu, i have begun the installation and i am at the step 3 :

1 : Install Ruby. Make sure it contains ruby.h and intern.h and  
related files. It's also recommended to have libruby.so. Those extra  
files may be in a package called ruby-dev if you are using RPM or DEB/ 
FINK. If you are building Ruby yourself, it's better to configure  
ruby with --enable-shared, else you won't have libruby.so (but you  
will still have libruby.a). If you need to have two Rubies at once,  
for example Ruby 1.8 for running Rails and Ruby 1.9 for running  
GridFlow, you may build Ruby 1.9 with the option --program-suffix=19  
which will help distinguish the two Rubies. It's also possible to  
have two Rubies installed without that option, but it might be  
complicated. If you install into a system directory, you may have to  
run ldconfig after installing Ruby.

	OK, i have downloaded it with Fink (install binary package)

2 : Download GridFlow from the website and uncompress it, or get it  
from the CVS server.


3 : Run ./configure from the gridflow directory. Make sure it detects  
all the components you want to use with GridFlow. If your OS is  
Debian or Ubuntu you would run ruby1.9 configure instead so that it  
doesn't use ruby 1.8. In MacOS you would normally use FINK to install  
those extra components: libjpeg libjpeg-shlibs libpng-shlibs libpng3  
libpng3-shlibs libmpeg libmpeg-shlibs

	OK, i have downloaded them with Fink (install binary package)
	In terminal : /gridflow-0.9.0 rybn12$ ./configure
	i get :

You should install gcc 3.x; gcc 2.9.x is no longer supported
(you might use --force-gcc3 to pretend at your own risk)

4 : Note: you may have to set CPLUS_INCLUDE_PATH to indicate where to  
find *.h files, and you may have to set both LIBRARY_PATH and  
LD_LIBRARY_PATH to indicate where to find *.so or *.aor *.dylib or  
*.bundle or *.dll or *.lib files.
5 : Note: you can do ./configure --help to get a list of supported  
options. You can use them to ignore the presence of troublesome  
libraries and select debugging level. With --use-compiler you should  
use a version of g++, not directly a version of gcc, else you get  
undefined symbol problems. Some versions of gcc/g++ are troublesome.
6 : Run make to produce the executables gridflow.so and  
gridflow.pd_linux or similar
7 : With a text editor, create ~/.gridflow_startup and write  
something like GridFlow.data_path << "/pd/extra/gridflow/images" to  
tell GridFlow where to find additional folders containing images or  
movies you want to use with GridFlow.
8 : Ltilib (optional, linux only): The LTI-Lib is an object oriented  
library with algorithms and data structures frequently used in image  
processing and computer vision.
1 : Download and install ltilib version 1.9.15 from http:// 
2 : in optional/rblti do: make
9 : Loading GridFlow:
1 : PureData : With a text editor, modify or create ~/.pdrc and write  
-lib gridflow.
2 : ImpureData : In the ".pdrc editor", add gridflow to the list of  
3 : plain Ruby : the command require "gridflow" will load gridflow.so.
Note that on MacOS the dot-files are invisible in the Finder but you  
do cd ~/Desktop; ln -s ../.pdrc "PureData Configuration" to make an  
alias on the Desktop. Note also that on Windows the dot-files are  
even more trouble.
