Graphviz Dot failing to remove overlaps due to missing library

Question

I am trying to run the following dot command from the command line:

dot -v ~/Documents/FlowGraph/dot_sample_1_full.dot -Tpng 'Documents/FlowGraph/sampleOutput.png' -Ksfdp -Goverlap=false

but it is failing with this output:

Error: remove_overlap: Graphviz not built with triangulation library

I've Googled and found this thread, which suggested:

gts has to be installed before graphivz so enter 'sudo brew remove graphviz' to remove graphivz and 'sudo brew install gts' and 'sudo install graphivz' to install graphivz with gts.

but that didn't seem to work. I'm still getting the error so either I didn't do it right, or that wasn't the solution for me.

How do I add the triangulation library to graphviz?

Answer 1

I had a similar problem on macOS with sfdp and the following is what solved it.

$ brew uninstall graphviz  
$ brew install gts 
$ brew install --with-gts graphviz

Answer 2

Homebrew doesn't support command line install options anymore, so the previous answers will not work anymore.

However, by accident i discovered that removing graphviz, installing gts, then installing graphviz works. It seems that graphviz will use gts if it isnt installed, but for some reason, it isnt a dependency.

brew remove graphviz brew install gts brew install graphviz
