More problems with Graphviz Tools

The graphviz library has to be installed on the machine that is expected to do the processing. If you want your website on the host to work with it, the "dot" command must be installed on the host.
If you are developing locally, the executables must also be installed locally.

The libraries and executables usually have to be installed by the host administrator. If they have not and will not do this for you, you can't use this feature.

With a certain level of shell access to the server, you can theoretically build the code in your own account (with ./configure --prefix=$HOME etc) , but it's really quite complicated for first-time users, and would be frustrating without a lot of background. It is much easier if the sysadmin will do it for you.

For more information, see the documentation for your OS and build tools (like "make"). It's tricky if you've not done it before.

/home/familyt9/php/dot is apparently not the right path

If, on your server, you can log in and type
dot -?
And see something like

Usage: dot [-Vv?] [-(GNE)name=val] [-(KTlso)<val>] <dot files>

in response, then the required library is indeed installed.

If that doesn't work - and you instead get the message

-bash: dot: command not found

then the required command is not available. That's what "command not found" means!

If you entered /home/familyt9/php/dot and still got "command not found", that's not the right path.

If you have actually installed graphviz on the system, then just typing 'dot' would work. If it doesn't, then it isn't there.

If you've installed it in a strange place, then you can enter the path directly - like the instructions say to.

But it really sounds like you have not got the graphviz package installed.

The download page is here http://www.graphviz.org/Download.php
Just choose the most recent version (highest version number) for your system!

If you prefer to use the tgz version, The instructions for building it on your system are still here http://www.graphviz.org/doc/build.html

... but it's really quite complicated for first-time users, and would be frustrating without a lot of background. It is much easier if the sysadmin will do it for you.

You need to get familiar with 50 other things first - like the commandline, make, and reading system documentation. It doesn't even sound like you are using a terminal yet.

On the download page for Ubuntu there are a bazillion links to download seemingly the same version of the source:

graphviz_2.26.3-1_i386.deb
libgraphviz-dev_2.26.3-1_i386.deb
libgraphviz4_2.26.3-1_i386.deb
libgv-guile_2.26.3-1_i386.deb
libgv-lua_2.26.3-1_i386.deb
libgv-ocaml_2.26.3-1_i386.deb
libgv-perl_2.26.3-1_i386.deb
libgv-php5_2.26.3-1_i386.deb
libgv-python_2.26.3-1_i386.deb
libgv-ruby_2.26.3-1_i386.deb
libgv-tcl_2.26.3-1_i386.deb
graphviz-dev_2.26.3-1_all.deb
graphviz-doc_2.26.3-1_all.deb

Do I need all of these?? I used command line to install via "sudo apt-get install graphviz". I think it might have pulled in a lot of these things.. but I'm not sure and don't know how to tell.

My status report indicates: "sh: modules/graphviz_filter/dot: not found"
How do I ensure this "dot" library is installed?

Re #9: Just make sure that on the Ubuntu console, typing:

dot -V

gives you something like:

dot - Graphviz version 2.20.2 (Wed Sep 16 11:12:11 UTC 2009)

To make sure Drupal is picking it up, go to admin/reports/status and check the Graphviz tools key: it should report the same.

On that list there is only one file that is called graphviz.{version}-{arch}.deb
That would be the one.

But if you are on debian - then apt-get would do it for you. What you typed should have worked.

If, on your server, you can log in and type
dot -?
And see something like
Usage: dot [-Vv?] [-(GNE)name=val] [-(KTlso)]
in response, then the required library is indeed installed.

If your status report - not the commandline response - says it has the wrong path, then you should enter the right path into the settings.
which dot will tell you what the right path is.

Ah hah! That "which dot" command was what I've been looking for. I hadn't come across that and I think that is where the problem lies.. However now I just need a command that will allow me to change "modules/graphviz_filter/dot" (which is not found) to "usr/bin/dot" (which is what returns when I type which dot)
I'm having trouble finding relevant commands.. When I type "dot -?" I get a few things, but none of the commands seem to be relevant to what I'm trying to do. I also tried "man dot" and got a few more bits of information, but it all looks pretty specific to setting up the graphviz graphs themselves, and not configuring the setup. I tried "dot -c" (configure plugins) but it doesn't seem to do anything.

Can you advise me on how to change the dot directory to "usr/bin/dot"?

WOOHOOO!! got it! I was looking too hard, the path specification I was looking for was in the configure tab of the graphviz input filter.
Very excited to have graphviz (seemingly) working after several weeks of struggle!!!
Thanks guys!

Yes, the configure tab of the filter is (I think) a little bit far away from the normal places you'd expect to go looking for it :-/
But there it is.

Thanks dman for your support.
