Detailed Description

The modules of the Affordance Demo depend on Probabilistic Network Library (PNL -- http://sourceforge.net/projects/openpnl/).

To successfully install and use it in the iCub project, there are a few additional steps necessary. Subsequently the installation procedure is described step-by-step for linux/unix systems:

 # get the latest release from http://sourceforge.net/projects/openpnl/files
 wget http://sourceforge.net/projects/openpnl/files/openpnl/PNL%20Release%201.0/PNL_Release_1_0_linux.tbz/download
 # unpack it and change to the created directory
 tar xjvf PNL_Release_1_0_linux.tbz
 cd PNL
 # make the necessary script executable
 chmod +x configure configure.gcc install-sh
 # configure the build system such that it is using gcc-4 (preferable gcc-3.4 to reduce issues with other parts compiled with gcc-4)
 ./confiugre.gcc CC=gcc-3.4 CXX=g++-3.4 --prefix=/usr/local
 # compile and install
 make
 make install
 # rename the the installed library in order to differ it from the library that comes with OpenCV
 mv /usr/local/lib/libcxcore.a /usr/local/lib/libpnlcxcore.a

ATTENTION! Make sure your installation prefix doesn't interfere with your OpenCV installation. Renaming that library only serves the purpose of allowing our CMake find script to differ between the PNL version of the library and the one that comes with OpenCV.

The libraries dependency on GCC-3 requires one to compile the module with the same compiler.

An alternative to the usage of GCC-3 is to fix the headers of the PNLibrary.
