[mlpack] Introduction GSoc 2018

[Evgeny Freyman]

Hi Rahul,

Just getting started with MLPack myself and had the similar problem. The
solution is:

1. As far as I know gcc is for C and g++ is for C++ language, so you need
to use g++
2. You didn't specify dependencies, thats why you got lots of unresolved
references. The proper way to compile your code is:

g++ -std=c++11 cov.cpp -lmlpack -larmadillo -lboost_serialization
-lboost_program_options -lboost_unit_test_framework

granted that you installed MLPack (ran "make install" command from the
instructions). Some of those Boost's dependencies may be redundant here, it
depends on what you use in your code.

Be careful to specify your source files before list of dependencies.
Thanks *rcurtin
*for clarification.

All the best
Eugene Freyman
