问题
I'm trying to make some Networkx Graphviz graphs.
After running: pos = nx.graphviz_layout(G, prog = 'sfdp'). An error occured, saying:
Error: remove_overlap: Graphviz not built with triangulation library
After some Google research I found that GTS is the problem. Bug report stated:
The Graphviz package is built --without-gts. This is bad news for sfdp, which complains “Error: remove_overlap: Graphviz not built with triangulation library” and fails to produce the beautiful output it creates when compiled --with-gts
Looking at comments ( on bug report ), someone said that the upstream sources for Graphviz are kept at link but I couldn't find new versions to download.
On package list I have the latest one (2.36 for trusty).
Anyone else having problems with sfdp?
Any help will be greatly appreciated!

I know the question is for Ubuntu, but in case someone is having the same problem on macOS using homebrew the following worked for me:
brew reinstall graphviz --with-gts

For the ubuntu users, this is how I got grapvhiz to work on 16.04,compiling graphviz-2.40.1 from source:
In a first step , GTS needs to be installed , as graphviz looks for the gts.pc file.
Running
apt-file search gts.pc
Informs me I have to install 'libgts-dev' :
sudo apt install libgts-dev
next make pkg-config aware of the files:
pkg-config --libs gts
pkg-config --cflags gts
run configure to link in the gts library:
./configure --with-gts --prefix ~
make
make install
SFDP no longer throws the error 'Error: remove_overlap: Graphviz not built with triangulation library'
The command line codes for the pkg config I modified from this answer.

I might have it working for Ubuntu 14.04, YMMV
Download the following graphviz packages directly from https://packages.debian.org/search?keywords=graphviz
- graphviz_2.38.0-13_amd64.deb
- libcgraph6_2.38.0-13_amd64.deb
- libgvc6_2.38.0-13_amd64.deb
- libgvpr2_2.38.0-13_amd64.deb
- libltdl7_2.4.6-0.1_amd64.deb
- python-pygraphviz_1.3.1-1_amd64.deb
I used version 2.38.0-13 from the stretch(testing) group. You will need to remove the 32bit libltdl7 if present:
sudo apt-get remove libltdl7:i386
Install the packages directly with
sudo dpkg -i graphviz_2.38.0-13_amd64.deb
sudo dpkg -i libcgraph6_2.38.0-13_amd64.deb libgvc6_2.38.0-13_amd64.deb libgvpr2_2.38.0-13_amd64.deb libltdl7_2.4.6-0.1_amd64.deb
You can expect dependency errors. I cleared them with:
sudo apt-get install -f
And then re-install
sudo dpkg -i graphviz_2.38.0-13_amd64.deb
sudo dpkg -i python-pygraphviz_1.3.1-1_amd64.deb
The error no longer appeares though I would be hard pushed to say the graphs are any better.
