As suggested, I used ccmake to check the correctness of the library paths.
It seems that cmake detects correctly the location of
libblas/libatlas/liblapack,
but it still gives linker errors (I also tried to manually add the paths
to LD_LIBRARY_PATH).
It feels strange to me, because I installed all the packages through
apt-get.
I would have been less surprised to get these errors if I had compiled
and installed
all these packages by myself.
I will try to build everything again on a clean separate machine to see
if it gets better.

This is a faulty setup. These things should be in your LD_LIBRARY_PATH.
Maybe cmake detected them wrong? We also have manual options to set
that (try ccmake), and also a special option for ATLAS.

Hi,
the latest commits solved my issue. I am now able to compile
all the meta examples (except those which require the LAPACK library).
However, for curiosity's sake, I tried to compile everything after
installing
the ATLAS library (that includes also LAPACK and BLAS). The cmake
configuration goes well,
but when I try to compile the cpp meta examples or the shogun unit tests the
linker complains
that it cannot find some symbols (for example, dsyev_, dorgqr_ etc.).
Here the gist with the complete errors:

Is there a way to fix it? Thanks for the help!

Hi!
That will be unmet dependencies that are not clearly handled in our build.
The latest merge should solve the CMahalanobisDistance problem.
Let us know how things go

Hello everybody,
I am a computer science undergraduate student from Italy. Recently, I got
interested in the Shogun Project and I have begun to "play" with the code,
to understand its structure and its internal logics.
Unfortunately, I encountered some problem when compiling the cpp meta
examples.
Specifically, I get compilation errors on the file
examples/meta/cpp/distance/mahalanobis.cpp.
You can find the complete message at this link:

I have also tried to compile it manually but it gave me the same result.
I am on Ubuntu 16.04 and I have set up cmake with these flags:
-DBUILD_META_EXAMPLES=ON -DENABLE_TESTING=ON
(my gcc version is 4.9.3).
Am I missing something? Perhaps some configuration parameters?
Thank you in advance for the help!
Best regards,
Giovanni
