Trying to get DR-PROLOG up running, following the instructions found here.
I have installed SWI Prolog and XSB Prolog. In order to compile SWI-Prolog, I had to install the following packages in Ubuntu (9.04), as mentioned in the README.debian file:
libxext-dev libice-dev libjpeg62-dev libxinerama-dev libxft-dev libxpm-dev libxt-dev pkg-config
It is now possible to start the DR-PROLOG Java application, but not to start the DR-PROLOG engine (from the DR-PROLOG menu in the Java application) .
