graphviz-dot problem with simple example

[yerrochdi]

conda install -c conda-forge graphviz xorg-libxrender xorg-libxpm
pip install graphviz

works for me !!!!

[mingrammer]

What is your macOS version? I can't reproduce it. (with the same versions for all except Graphviz dot 2.42.2)

[jenisys]

Using macOS 10.14.x, graphviz was installed with brew (which normally takes care of macOS versions variances). Note that graphviz-dot is usable in principle, image= is also OK, I can open the PNG file by using the filepath.

One correction, installed graphviz package is 2.42.2, but if you ask dot for its version you get 2.43.0.

[mingrammer]

Oh sorry, Yes, my dot version is 2.43.0 too.

Hm. .. Could you please show your full dot code for the above diagram? I need to compare your dot code and mine.

[jenisys]

As already stated, the image=...attribute seems to be causing the problem.

# -- FILE: simple_diagram
digraph "Simple Diagram" {
	graph [fontcolor="#2D3436" fontname="Sans-Serif" fontsize=15 label="Simple Diagram" nodesep=0.60 pad=2.0 rankdir=LR ranksep=0.75 splines=ortho]

[mingrammer]

It's mine.

}

I don't understand why image= field causes the SIGILL error (illegal instruction) .. It could be an issue of dot installed on your system or some CPU / memory corruptions.

Could you try rebooting your computer? (maybe, can solve the corrupted memory problem..)

[mingrammer]

Is it solved?

[jenisys]

I retried it with diagrams-0.6.3, but the problem still exists (SIGILL, ILLEGAL INSTRUCTION), problem is the image=xxx attribute.

[mingrammer]

Rebooting can't solve that problem? Hmm ..

[mingrammer]

I close it. Reopen if same problem raises.
