Re: programming X
Assuming you have the X devel package as others have suggested, you may also need to tell the compiler where to find the headers: -I/usr/X11R6/include #include X11/Xlib.h should then work. Xlib is beastly and nasty, so if you aren't very familiar with C (especially if you're easily frsturated) it's probably a bad place to start. Gtk would be better, or even better, simple command-line programs. Gtk is more fun, but a small command line program is probably more sensible. :-) HTH, Havoc
programming X
Hallo there, I recently purchased the O'Reilly Xlib Programming Manual with the aim of learning how to write X applications. My problem though is I can't get basicwin.c to compile up at all! I even downloaded the O'Reilly version and that didn't work. The O'Reilly version complains that it can't load Xlib.h although my compile line reads gcc -g -lX11 -o basicwin basicwin.c I tried it with a -DSYSV also but to no effect. My version has fits complaining about undeclared variables. I suspect I need to include Xfuncproto.h but I'm not certain. My main question though is, should the example work exactly as written in the book or do I need to generate a GNU/Linux version? If so how? If the book's example should work then what am I doing obviously wrong? I can post the compilation error messages once I've retyped the source, I got annoyed and blew it away. Are there any newgroups I should subscribe to for this sort of information? thanks

I would doublecheck whether you have the X development package xlib6g-dev --prashanth

Code written using only POSIX functions and Xlib calls (e.g. all of the examples in the O'Reilly book) should be *very* portable, and will probably build without modification on nearly any Un*xish machine, save modifications to include and link paths as noted above. -- David Maze [EMAIL PROTECTED] http://donut.mit.edu/dmaze/ Hey, Doug, do you mind if I push the Emergency Booth Self-Destruct Button?
