My first question is what version of g++ and all of it's dependencies are you using? No compiler I can think of should complain about a recast from const char* from char*. I am using g++ 3.3 but I'll try with some earlier versions as well. Kirk -- Kirk Reiser The Computer Braille Facility e-mail: kirk at braille.uwo.ca University of Western Ontario phone: (519) 661-3061
