I’m just plinking around after having read the early chapters of the O’Reilly volumes 4a and 6a plus some Athena and Xlib stuff. I was itching to try some things. For my background see http://ab1jx.webs.com For graphics programming I’ve mostly worked in Turbo Pascal and Delphi.
So I get this error message in my second Intrinsics/Athena program and I’d like to know the possible causes of it. If I Google for it all I find are mentions of it cropping up in specific applications. There’s nothing mission-critical here, it’s just practice. Knowing where to find longer versions of error messages in general would be a good thing. I’m trying to make a simple oscilloscope type program. I’m using a Panner for an output screen. I can make a Pixmap and draw a grid onto it with XDrawSegments, test it with XWriteBitmapFile, but when I try to use XCopyPlane to copy to the Panner I get the unavailable message. I can use XDrawSegments directly on the Panner (well, once anyway), copy the grid into another Pixmap with XCopyPlane, most other things seem to work. Aside from the unavailable message I get a black rectangle where the Pixmap should be. Nothing shows up in /var/log/Xorg.0.log about it, and it’s not fatal: I can keep running the program. I wouldn’t have known it was there except I put a perror after the XCopyPlane to investigate the black Pixmap.
