You are correct that it wasn't simple to install. I have written some [User:DavidWhitten/Wgraph_Install_Notes notes] of my experiences.
 
 
One thing that could have helped would be ways to test things.
 
like to find out whether ImageMagick (convert) was installed,
 
I had to look until I found the source code for ImageMagick.
 
 
 
I used the command:  wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
 
 
 
 
 
I had to installed ImageMagick under the user I was using, rather than installed for the entire website.  Let's pretend the user name was fooimg.
 
I had to create a "local" directory under the /home/fooimg  since I couldn't put anything in /usr/local
 
on this machine.  I used the command: mkdir local
 
 
 
And when I did the command install command for ImageMagick, I could not just say ./configure
 
like the instructions said, but I had to instead type  ./configure --prefix=/home/fooimg/local/
 
( by the way ./configure --prefix=~/local  did NOT work, because the "configure" program wanted the actual place on disk to put into its generated script files. )
 
 
 
Then I had to use "make" to create the convert program...
 
 
 
The above steps are show in the following log of my command history:
 
 
 
  16  mkdir local
 
  17  cd ImageMagick-6.3.8/
 
  18  ./configure --prefix=~/local
 
  19  pwd
 
  20  ./configure --prefix=/home/fooimg/local/
 
  21  cd ..
 
  22  ls local/
 
  23  cd ImageMagick-6.3.8/
 
  24  make
 
  25  cd ..
 
  26  ls local/
 
 
 
I tried to install it, and it complained (but might have actually done what I need. I was surprised to find the stuff in the local directory later on:
 
 
 
  27  cd ImageMagick-6.3.8/
 
  28  make install
 
 
 
I ultimate got the computer to find the convert program for me, since I didn't know where it was put:
 
 
 
  34  find . -print | grep convert
 
  35  ./utilities/convert
 
 
 
I was doing this, because I wanted Wgraph (and mediawiki) to use the convert program to make thumbnails.
 
 
 
I used tar with xvzf (extract,verbose,compressed file) on the file I got here : aiSee_linux.tgz ((Thanks by the way))
 
 
 
  127  wget http://www.absint.com/dla/wgraph/aiSee_linux.tgz
 
  128  tar xvzf /home/visvis/aiSee_linux.tgz
 
  129  ls
 
  130  cd aiSee/
 
  131  ls
 
  132  lynx .
 
  133  ./setup
 
 
 
I had already purchased a license for aiSee for a different project, by the way.
 
by the way, this created a directory named aiSee  which I later had to rename as aisee (without the capital letter)
 
because somewhere the directory was referenced without the capital letter.
 
 
 
I tried running bin/aisee.bin and it complained about libXext  not being available.  I had to use apt-get to retrieve it (since I don't run X windows on this server)
 
 
 
 
 
I got your Recode executable and moved it into the bin directory under /home/fooimg/public_html/Wgraph
 
 
 
  mv recode ../Wgraph/linux/bin/
 
 
 
 
 
I did a lot of stuff, and I have the log which means I can tell you the steps, but just remember, I started from scratch, no mediawiki, no wgraph, no aisee, no ImageMagick, no X-windows extension library so I probably had to do stuff which a lot of people might not need to do.

David Whitten is the Chief Technology Officer of WorldVistA (http://www.worldvista.org) a U.S. 501(c)(3) nonprofit dedicated to affordable healthcare computing worldwide.

Yea! I just got Wgraph working on a private wiki. As I understand it, it only generates svg and png files. I wonder what would be necessary to generate image maps ?


Image maps might be somewhat complicated. But there is a good alternative: use the 'href' attribute for nodes.

BTW: It is not really simple to install Wgraph. Did you have problems? Are you using Windows or Unix? Do you see the need for improving the installation description?

You are correct that it wasn't simple to install. I have written some [User:DavidWhitten/Wgraph_Install_Notes notes] of my experiences.
