GridFlow Frequently asked questions

Q: How do I do a svn checkout / commit as a registered user on artengine?

1. Ask Mathieu for a svn account. (this is separate from regular user accounts at artengine)

2. Do:

• svn checkout https://gridflow.ca/svn/trunk mv trunk gridflow

3. To add a file to the svn repository do : 'svn add some_file.pd' (this step is not needed if you update an existing file) and 'svn commit some_file.pd' You may be prompted for your password unless it is cached

4. You may check that the file was uploaded correctly : visit http://gridflow.ca/svn/trunk for example

That's it!

Q: How do I get quicktime support for SuSE 9.1 +9.3?

A: First make sure you have the glib and glib2 devel packages installed.

In order to compile gridflow with libquicktime support, add these lines to .bashrc : export LIBRARY_PATH=/opt/gnome/lib export LD_LIBRARY_PATH=$LIBRARY_PATH

for 64bit systems, be careful to point to the correct path and use :

export LIBRARY_PATH=/opt/gnome/lib64:/usr/X11R6/lib64 export LD_LIBRARY_PATH=$LIBRARY_PATH

run exec bash

do ./configure, make
