Janina - I cannot find any information about error 127 from make, but I did manage to induce one to occur. I changed the name of my g++ compiler to a nonexistent name, and when I ran make again it ended with an error 127. So - is it possible your C++ compiler is not called g++? If it has another name, try changing the line in make that says "CC=g++" to the correct value. Chuck Visit me at http://www.mhonline.net/~chuckh The Moon is Waxing Gibbous (66% of Full)
