This documentation is based on the version of Samu tagged with "Judah".
Samu can only be run under Unix-like operating system such as GNU/Linux.
Samu requires the installation of the following packages.
- C++11 compatible compiler
- JDK (for install link-grammar, see the Troubleshooting/FAQ bellow)
- opencog/link-grammar
- Boost (sudo apt-get install libboost-all-dev)
- PNGwriter (make sure the PNGWRITER_ROOT environment variable is defined and points to the folder where you installed the PNGwriter)
Troubleshooting/FAQ
When installing link-grammar (https://github.com/opencog/link-grammar) we got the following error "cannot find jni.h in standard location".
Please install JDK (1.8.*.tar.gz from Oracle: http://www.oracle.com/technetwork/java/javase/downloads/index.html then extract it into the directory ) and set the env variables JAVA_HOME and PATH:
export JAVA_HOME=<path to jdk>jdk1.8.*
export PATH=$JAVA_HOME/bin:$PATH
Finally the variable CPPFLAGS should be set before typing the ./configure command as follows:
export CPPFLAGS=-I$JAVA_HOME/include
Building Samu, uncomment the appropriate lines in the file CMakeLists.txt. For example, if you have CUDA installed on your system Samu may be built with CUDA support,
set(CUDA_LAYERS ON)
#set(CUDA_LAYERS OFF)
Or, if you want to use TUI you need uncomment the following line:
set(DISP_CURSES ON)
#set(DISP_CURSES OFF)
After finishing the edit of the CMakeLists.txt type cmake .

If cmake . finishes without problems you can run the make command to build Samu.
To run Samu, type the following command
./samu 2>out
If you use ncurses you will see something like this:
In another terminal window, run the command
tail -f out|grep iter
to see Samu's "training curve".
