Just thinking... two possibly easier ways to install all the required deps for building on Ubuntu: 1) Could I download the gitpackaging repo and run whatever incantation is needed to get Ubuntu to parse the debian/control file and install the deps that that describes. Is that simple to do? It's abou...

Sorry I forgot that one. Yes install libproj-dev this is a definite packaging problem specific to Xenial libvtk-dev. I had to add it to the PPA as well. Ah, that's better. Now compiling... It gets further... src/Gui/DownloadManager.cpp:36:24: fatal error: QWebSettings: No such file or directory com...

Thank you jmaustpc and sgrogan. make sure that you have installed all the updates for 16.04 Yes I had installed all the standard Ubuntu updates, security fixes and backports. that file is part of the package "python-vtk", have you installed it? Ugh, no. I missed that. Thank you for catchin...

Thank you, Jim. I've changed the pw now.

I saw "we" deliberately: I recognize it's a community thing and I am willing to help, by testing the instructions and/or by doing the Wiki editing, if you like.

I've just upgraded Ubuntu to 16.04 and have immediately run into trouble compiling FreeCAD. I'm using a Git source tree that was up-to-date yesterday and successfully built on Ubuntu 14.04 yesterday before I did the system upgrade. I haven't touched the source code since then. $ (cd build/ &&...

The file .travis.yml contains a "sudo apt-get install ..." command ... but it doesn't have the right dependencies for Ubuntu 16.04. What particular distro of Linux it is targeting? Is it meant to be currently useful, and if so should it be updated to target some specific recent common dist...

Please can we add instructions to compile on Ubuntu 16.04 "Xenial"? The Wiki page CompileOnUnix only has 13.x and 14.x. (I recommend we delete the 13.x section or archive it to an "old distros" page.)

p.s. The system upgrade was still downloading new packages and hadn't started installing/modifying/removing anything by the time the FreeCAD build completed, so I don't believe it affected that build.

The good news: I overcame the problem and got a full build including the Draft workbench. The bad news: I don't know whether it was because I cleaned up the in-source-tree build I had been using since last year and did a fresh build (out-of-source, in a new subdirectory) or because I also pulled the...
