Description

I am using 0.7.5dev on centos linux. I have set the out_format to svg. And I get:

The command ['/usr/bin/dot', , u'-Tsvg', u'-o/tmp/trac/gvcache/90cf7ab897a5d62a533154aaeed4d74c51701f89.dot.svg'] failed with the the following output:

Error: dot: can't open

Can you execute the dot program on the command line (dot --help)? That would be the first step to ensuring that you have graphviz correctly installed.

If not it sounds like dot might not be installed correctly. If you can, then you can type "which dot" to determine where this was set, then you can probably arrange so that the plugin looks in a different place, or you can symlink dot into where it is expected (which ever you prefer).

Yes, I can execute dot.

/usr/bin/dot -V

returns dot - Graphviz version 2.12 (Thu May 24 17:16:50 UTC 2007)

/usr/bin/dot ""

returns the same error message Error: dot: can't open

Should the first argument be empty?
