 Steps to get more information about errors in C++ code:
 
-- build BrainFlow's core module and C++ binding in debug mode. In files like tools/build_linux.sh default config is Release, so you need to change it to Debug
+- build BrainFlow's core module and C++ binding in debug mode
 - reproduce your issue using C++ binding
 - run it with debuger and memory checker

+Example for Linux, for other OSes it's similar::
 
-    vim tools/build_linux.sh

-    bash tools/build_linux.sh
