I have successfully installed espeak on my slackware 10.2 system, but what I had to do doesn't quite conform to what Josh recommended. The speakup source is a little from what I'm used to. There is no Makefile in the top directory, but there is one in the src subdirectory. In that Makefile, I found no line like Josh suggested, i.e., one containing the "lflags" However, there was a line copntaining "-portaudio" and adding "-lpthread" and then runing make did the trick. Perhaps there are varying versions of espeak's source. Good luck to any who try! Larry
