# Install Dependancies
SWIG:
brew install swig

Armadillo:
brew install armadillo

Build Trajectory Generator Library and Wrap in Python

Create interface:
swig -c++ -python trajectorygenerator.i

Build library and link armadillo:
g++ -fPIC -c trajectorygenerator.cpp -O2 -larmadillo

Build wrapper:
g++ -fPIC -c trajectorygenerator_wrap.cxx -I/usr/lib/python2.7 -O2 -larmadillo  

Note make sure that the Python.h file path is right. usually in most systems you will have to change to pythonX.X/Python.h

Build file containing specific function which we will expose to APEX tool:
g++ -fPIC -c libtraj_gen_v2.cpp -O2 -larmadillo

Link:
g++ -shared trajectorygenerator.o libtraj_gen_v2.o trajectorygenerator_wrap.o -L/usr/lib/python2.7 -lpython2.7 -o _trajectorygenerator.so -O2 -larmadillo
 
Make APEX.py executable:
chmod +x APEX.py

Run APEX:
