ERROR: could not spawn neato -Tx11: no such file or directory (ENOENT)

[piperod]

I am running Julia v.0.5. and Graphs v. 0.6 on OS El capitan. The full error I get is :

Make sure you have Graphviz installed. If you are using Homebrew, simply issue

$ brew install graphviz

in a terminal window.

Also see #172.

@piperod, can you give a minimal way to reproduce this error?

[piperod]

Thanks @kmsquire and @jagot for your answers. I did what @jagot suggested and it worked, but now I am getting this message : "Format: "x11" not recognized. Use one of: bmp canon cgimage cmap cmapx cmapx_np dot eps exr fig gif gv icns ico imap imap_np ismap jp2 jpe jpeg jpg pct pdf pic pict plain plain-ext png pov ps ps2 psd sgi svg svgz tga tif tiff tk vml vmlz xdot xdot1.2 xdot1.4"

And @kmsquire I am following the steps described in the documentation at 1.8 https://media.readthedocs.org/pdf/graphsjl-docs/latest/graphsjl-docs.pdf

Hi @piperod, are you still seeing this error? Seems to be working fine on Ubuntu 12.04 and 14.04...

 g = simple_graph(3)
add_edge!(g, 1, 2)
add_edge!(g, 3, 2)
add_edge!(g, 3, 1)
plot(g)

[dehann]

A work around is to export to file and convert to pdf separately:

fh = open("temp.dot","w")
write(to_dot(g))
close(fh)

Then in command line you can run neato (or equivalent graphviz process) to draw the graph:

neato -Tpdf temp.dot -o graphpicture.pdf
