I found this git tree over the weekend. What I found is that in order to run the autoconf scripts there were a couple of other dependencies, which appeared to be quite minor, so I installed them. I am back at work right now, and I cannot remember exactly what they were. Mainly 2 or three items with "proto" in their names. Then I was able to compile something and install it. The X server however would not work. It complained that the ati driver has a different version number from the xserver so it could not be used. So then I found the git source for the ati driver and compiled it, too. Then things still did not work. What I am missing is some kind of roadmap through the dependencies, here. To me as something of an outsider to X development, the whole thing seems to be a godawful maze of hidden dependencies, and one does not know how to proceed through it to get from one side to the other. Sorry to say that, but I am an outsider to X development, as I said, and that is my instinctive reaction. Perhaps you can give some advice about how to go about this? To the above, I should add that I am not exactly a stranger to writing code. I have contributed actively to Gphoto and to the gspca webcam driver tree in the kernel. So I do not have any phobias about this. But I did spend most of the day yesterday trying to make this thing work, and I did not succeed. So clearly there is something that I am missing. As i said, what I seem to need is a roadmap about how to get through the maze. It seems that the sequential order of compiling and installing things is crucial here, and as far as I know nobody has gone to the trouble to document that. Theodore Kilgore
