Compilation error

[goldturtle]

I am using Ubuntu 16.04 and did the following:

git clone https://github.com/shogun-toolbox/shogun.git
cd shogun
git submodule update --init
mkdir build; cd build; cmake ..; make -j 8 ; make install

I got the following error:

What should I do?

@goldturtle in case you just want to use shogun out of box you can simply use the conda-forge package or the ppa from here: https://launchpad.net/~shogun-toolbox/+archive/ubuntu/stable

otherwise i'll try to reproduce this error but based on our buildbot 16.04 build should be working:

Looks like this happened to other people too:

#2841

Reading the last comment, though, I wouldn't know how to change the include path in a proper way.

[vigsterkr]

Do you have somewhere else shogun already installed?

No. I'd like to compile it from scratch because I want to play around.

I'm guessing this can be closed
