Graphviz's sfdp is seriuosly crippled without a triangulation library

Fede,

How old are your graphviz sources?

When I look at HEAD in git, it looks like --with-gts is the default.

Perhaps you are missing the gts-devel package (maybe libgts-dev) and
configure is trying to fall back to a non-gts build?

I'm using the grapviz_2.38.0-5ubuntu0 sources package from Utopic. The one linked to from http://packages.ubuntu.com/utopic/graphviz. Inside graphviz_2.38.0-5ubuntu0.1.debian.tar.xz you will find a debian/rules file that configures the package --without-gts.

In http://changelogs.ubuntu.com/changelogs/pool/main/g/graphviz/graphviz_2.38.0-5ubuntu0.1/changelog, in the release notes for graphviz (2.20.2-1) you will find a note that says “Add “--without-gts” to configure arguments to make sure not to link against GTS, at least for now.” Unfortunately, no justification why that was a good idea at the time.

Which git are you looking at?

So, you need to contact the packager of those sources, sorry, thats not me.

I'm one of the upstream developers. The upstream sources for graphviz
are kept at:
     github.com/ellson/graphviz

Thank you for looking into this.

BTW, I didn't contact you directly. I reported this through Ubuntu's bug
tracker. I expected them to escalate to Debian before this reached you.

Fede

Yes sorry, I was premature in responding.

Unfortunately these bug tracking systems don't have automated
escalation, or upstream tracking mechanisms,
so I try to monitor the distributions for bugs that really are mine.

Status changed to 'Confirmed' because the bug affects multiple users.

Greetings. Is there any hope of seeing graphviz with sfdp with libgts (triangulation) back ported to ubuntu 14.04 which I'm using for a project in AWS? Otherwise I can just build everything from scratch like I'm always telling other people :-)

Can you use alien to convert a gts rpm to a deb ?

This is still an issue in xenial. Any chance to get this fixed?

This still affects graphviz in Yakkety.

graphviz is in main and gts is in universe. To get gts in to universe and fix this bug, someone will have to complete the paperwork for a MIR (main inclusion request) and Canonical will have to approve the request:

This issue no longer occurs in Cosmic. Installing graphviz now pulls in a 'libgts-0.7-5' package, so I assume that the fix that was made in the Debian package has found its way to Ubuntu.
