[v0.17] Dependency graph: Graphviz failed to create an image file

[miniellipse]

It looks like Graphviz was recently moved to GitLab for its code and web hosting, the complete website was changed and they no longer provide older versions than 2.38.

So what does one do to make it Graphviz work on a windows machine? The weird part is I do not understand how I broke it in the first place. Maybe I was trying to install too many FCAD dev versions??!

The number of FreeCAD versions is of no importance here - unless you run completely out of harddisk memory. Then all sorts of unexpected things can happen.

You mean that it won't work anymore for any model, not only for one single FCStd document?

Here is the 2.41.81 dev version that I downloaded and works for me:

Ok. I rechecked things and the problem is only that one fcad file. Something in that file caused dot.exe to crash. I made some changes to that file and refreshed things, and now it works. Appreciate all the help as always in this forum. I love FCAD!

I've witnessed that for files posted on the forum from time to time where Graphviz can't generate a graph. I don't know why.

I can confirm in FreeCAD v0.18 with Graphviz 2.38, this is still a problem, this time on Windows10 x64.

I could make a literal cube in PartDesigner, "Graphviz failed to create an image file", every time.

Hot swapped the bin directory provided above into my existing 2.38 install, and voila, dependency graphs work (this is the first time I've seen one!)

I don't understand:
You have a 2.38 version, which fails.
And if you switch to the same 2.38 version it works?

No. He swaps the files in the 2.38 installations with the files from the 2.41.81 zip that I posted above so now folder is still called 2.38 but inside it there are 2.41.81 files which are working.
Current GraphViz dev builds are hard to navigate here https://ci.appveyor.com/project/ellson/graphviz-pl238 that is why I posted my working file.

Thanks for the clarification.
