OK, it seems that GF is a powerfull tool. But why there is no basic
tutorial for beginner to install it ?
Because :
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.
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
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://
ltilib.sourceforge.net/
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
libraries.
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.
- Where to DL Ruby and how to install it (macosx) ?
- OK
- With Macosx, how to use Fink (what we do with it ?) what can we do
with Fink to configure GF ?
4) Set CPLUS_INCLUDE_PATH : where is it and what is it ? Where to
find *.h files : where is it ans what is it ? And you may have to
set both LIBRARY_PATH and LD_LIBRARY_PATH : where is it and what is
it ? To indicate where to find *.so or *.aor *.dylib or *.bundle or
*.dll or *.lib files : idem ?
5) It's like chinese langage for me.
6) OK
7) And we save it on the desktop ?
8) For linux only (equivalent for OSX ?)
9) OK
Note) On MacOS the dot-files are invisible in the Finder : are you
sure ?
I think a clear documentation is good for people like me. Then we
could install GF without problem. This would multiply the chances to
have GF by 10 ? ;).
Why GF is not include with pd-extended ?
Thanx for your answer.

there is a lot to learn, when learning gridflow. and learning it
is very interesting. i don't have an academical/mathematical
background and for me gridflow is one of these tools, that help me
understand theories, that i wouldn't have a chance to understand
whithout seeing them implemented and working. this applies also
very much to pd, i think. would you consider pd to be a tool only
for dsp experts and academic musicians?Exactly. GridFlow is designed like Pd is, while GEM and PDP both
try to hide much more about video and other data types, than what
Pd ever hides. (One hides less, by allowing lots of data converters
and data operations in a way that you can access the data the way
you want, instead of having to rely solely on readymades)_ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC Canada
