What is Shark?

SHARK is a fast, modular, feature-rich open-source C++ machine learning library

Because of Installing Shark depending on Boost and CMake

Install steps for Shark:
1. install the dependency software
sudo apt-get install cmake cmake-curses-gui libatlas-base-dev libboost-all-dev

2. download the Shark SRC
svn co https://svn.code.sf.net/p/shark-project/code/trunk/Shark

3. enter the Shark directory
cd Shark

4. cmake the src
cmake -DOPT_ENABLE_ATLAS=ON -DOPT_ENABLE_OPENMP=ON

If you have a custom/manual Boost installation, please identify your boost include and library directories and use instead:

ccmake -DBoost_NO_SYSTEM_PATHS=TRUE -DBOOST_INCLUDEDIR=/path/to/boost/include/ -DBOOST_LIBRARYDIR=/path/to/boost/lib/ <SHARK_SRC_DIR>

5.compiling the src
make

6. verify the installation finished.
make test(ctest)

If all the tests Passed, It will print the following Log:
