Boyer; President, Chief Software Developer Abilitiessoft, Inc. http://www.abilitiessoft.com Madison, Wisconsin USA Developing software for people with disabilitie Some people who have tried to test BrailleBlaster with Orca have encountered undefined symbol messages even after following all instructions and installing the latest versions of liblouis and liblouisutdml. This is because some distributions do not have a recent version of liblouis. It is therefore necessary to find where the distribution has placed its version of liblouis and either delete it or copy the .so file that was just installed into that location. John
