With Octave on Ubuntu 16.04: Stuck in installation at cmake

[carbonox-infernox]

I am following the instructions here: http://www.shogun-toolbox.org/install#manual-basics

When i do cmake .. -DINTERFACE_OCTAVE=ON

I get the error
CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message): Could NOT find Octave (missing: OCTAVE_ROOT_DIR) (found suitable version "4.4.1", minimum required is "3.6") Call Stack (most recent call first): /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE) cmake/FindOctave.cmake:189 (find_package_handle_standard_args) src/interfaces/octave/CMakeLists.txt:1 (FIND_PACKAGE)

I checked this thing and the reason is that OCTAVE_ROOT_DIR is detected via octave-config -p PREFIX which is not supported anymore. I didn't find any mentions of that in CHANGELOG of Octave but I guess we should adapt FindOctave. Luckily, this directory seems to be unused. This means deleting it from the argument list of find_package_handle_standard_args should help.

The problem now is that it fails during make. I got it up to 75% on the 2nd or 3rd try, but now every time i run it it only makes it to 2%. I'll copy the error message:
