unable to open .dot file

Hi, I'm a newbie, and have been looking around for a solution to this problem, but so far no luck. Any help is greatly appreciated! I downloaded and installed Graphviz for MountainLion, and everything seemed to have gone without problems. However, every time I try to open a .dot file, I receive the message : "Unable to open the document "filename.dot" . Any suggestions? Thanks for your help!

won't open .dot files on mac running ML

Hi,
I'm a newbie to this, and have been searching a bit for a solution to my problem, but so far no luck. Any help is greatly appreciated!

I have a .dot file, which I want to open with Graphviz, but I repeatedly get the message "The document "XXXX.dot" could not be opened". I'm running Mountain Lion, and the install seemed to have worked fine.

Any thoughts? Thanks!!!!

unable to use graphviz with php 5.4.17

Hi,

I use php 5.4.17 from the REMI repo (http://blog.famillecollet.com/) in RHEL 6.

And installed graphviz-php from the official graphviz repository.

Bute when I restart my apache, I get the following error in the php error log:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gv.so' - /usr/lib64/php/modules/gv.so: undefined symbol: php_body_write in Unknown on line 0

It seems, that graphviz-php isn't working with php 5.4. Or did I missed something?

Thanks in advance!

Extra content at the end of the document

Hello,
I want to show a graph + some text for a webpage.
This is my simple code:   

postupgrade script for local

  I downloaded the MAC package file graphviz-2.28.0.pkg and tried to install

postupgrade script for local

 I downloaded the MAC package file graphviz-2.28.0.pkg and tried to install the program on my system (MAC OS X.5.8).
However, I get the following error: "Install failed. The following install failed: run postupgrade script for local." 
on this website "www.graphviz.org/bugs/bb1618.html" I found the same problem, but does not offer a solution. I checked for the files: "/usr/local/bin/gv-fc-cache" and /usr/local/lib/graphviz/config6 (or 5?). only gv-fc-change exists.
How can I solve this issue?
 

Dot: Strange Error

Hi, I'm new to Graphviz so this maybe a stupid question but here goes...
I output a .dot file from R using LoopAnalyst (http://cran.r-project.org/web/packages/LoopAnalyst/index.html)
 
> graph.cem(matrix, file="/location/filename.dot")
 
and then from the command prompt typed
 
$ dot -Tps /location/filename.dot -o /location/filename_graph.ps
