I have downloaded the source files tora-2.1.3.tar.gz.
I compiled it on windows XP after big troubles because I use to work with Visual studio and do not know much the command line. I still cannot debug the project.
I have an oracle 11G database and tried to use the "Table index" window. I attach the source files I changed to make it work.
Hope it can be useful for the life of this project.
