Error compling version.cpp

[johnny555]

When compliling using CMake with python-module switched on under ubuntu 14.04 I get the following error:

I can compile just fine on Ubuntu 14.04. Can you please post here what steps are you using (by the way, are you following the quickstart?) to get the source code, configure, and compile?

I initally tried to follow: http://www.shogun-toolbox.org/doc/en/current/installation.html

but by cloning the git repo instead. It seems that is out of date as there are is no ./configure file. When I noticed that there were cmake files I created a seperate build directory to run CMake in. I also chose to bundle ARPREC, COLPACK, EIGEN, JSON, NLOPT.

I configured CMake to build the python-modular library, I also had to apt-get install SWIG

Following that I configured, generated Cmake and then make -j4

I didn't notice the QUICKSTART, but other than change the install prefix I dont think I did anything differently.

What branch of the repository are you compiling? I guess it is either master or develop. You should go for develop. On 16 Oct 2014 01:05, "johnny555" notifications@github.com wrote:

mmm this has been encountered just now by somebody else... :S looking into it, but interestingly enough travis-ci builds are done with ubuntu 14.04 docker images and have not encountered this before there :(
