Before doing this, you'll need to nuke `config.cache'.
- If you get errors about not being able to find Motif or Athena (the
- Xm/ or Xaw/ header files), and you can't find them on your system,
- then your system is horked and your vendor is lame. Perhaps the
- problem is that you don't have some kind of ``development option''
- installed. Xt/ and Xaw/ (Athena) are free and available on all
- systems; Xm/ (Motif) is available on all commercial systems except
- SunOS 4.x and some early releases of Solaris. For Linux and other
- free Unixes systems, a Motif clone is available from
- http://www.lesstif.org/.
+ If you get errors about not being able to find Gtk, then perhaps

RUN-TIME PROBLEMS:
* Is the problem in the driver (`xscreensaver'), the GUI
(`xscreensaver-demo'), or in the graphics hacks?
- * If the problem is in the GUI, was the it built using
- Motif, Lesstif, or Athena? Which version?
+ * If the problem is in the GUI, was it built using Gtk, Motif,
+ or Lesstif? Which version?
* If the problem is in one (or more) of the hacks, which ones?
If you're not sure, try running `xscreensaver-demo' to go
where
If the bottom few lines of the output don't include the functions
- `main_loop()' and `main()', then something's wrong: are you sure
- the core file came from that program?
+ `main_loop()' and `main()', then something went wrong, and the
+ core file is bogus. If the lines it prints out contain only
+ question marks, then the core file is bogus. Are you sure the
+ core file came from that program? Did you compile with -g, as
+ explained above? If you don't compile with -g, the core file
+ won't have any information in it.
+
+ Never ever ever mail me (or anyone) a core file. They are huge,
+ and are only meaningful on the machine that generated them, with
+ the exact executable that generated them, neither of which anyone
+ but you has access to. Don't mail me a core file unless you're
+ also planning on mailing me your computer.
* If it gets an X error, where did it come from? Run
xscreensaver with the `-sync' command-line option. When `-sync'
diagnostics; the `-no-capture' option prevents the data from being
displayed on the screensaver window as well.)
- You also might want to use the `-timestamp' option, which will
- cause the xscreensaver messages to include the time at which
- they were printed.
-
* If the problem is intermittent, you might want to capture the
log information to a file and examine it later. For example,
you could start it from your login script like this (csh syntax):
- ( cd ~/src/xscreensaver/ ; \
- xscreensaver -sync -verbose -timestamp -no-capture \
- >>&LOG & )
+ xscreensaver -sync -verbose -no-capture >>& saverlog &
* Hackers only: If you're feeling adventurous enough to run gdb
on the xscreensaver driver process itself, make sure you've
