There are many compilation dependencies. The configure script will tell
you what is missing. At the least, you will need development versions of
these libraries. Append "-dev" or "-devel" to most of these:
- perl pkg-config gettext intltool libx11 libxext libxi libxt libxft
- libxinerama libxrandr libxxf86vm libgl libglu libgle libgtk-3
- libgdk-pixbuf2.0 libjpeg libxml2 libpam libsystemd elogind libwayland

+ libxft libxinerama libxrandr libxxf86vm libgl libglu libgle
+ libgtk-3 libgdk-pixbuf-2.0 libjpeg libxml2 libpam libwayland
+ libsystemd elogind
You can build a package-manager version with "make rpm" or "make deb".

Other files generated as a part of the build process:
- petri is similar, except with tons of XFillRectangle, which, at two
triangles each, is a lot of geometry.
+ - extrusion doesn't work because no libGLE.
+ - glitchpeg is just too hard.
+ - mapscroller requires perl.
+ - vidwhacker requires perl.
+ - webcollage requires perl.
+
- Undiagnosed problems:
- antinspect has some kind of masking problem. Maybe only in emulator?
- discoball doesn't draw rays.
- endgame is insanely slow.
- esper images display as black.
+ - flurry is all black.
- glblur is grayscale instead of color. Endian or packing problem?
- queens is insanely slow.
- sonar doesn't display properly, but once it does, test icmp.

+.SH NAME
+alienbeacon \- screen saver.
+.SH SYNOPSIS
+.B alienbeacon
+[\-\-display \fIhost:display.screen\fP]
+[\-\-visual \fIvisual\fP]
+[\-\-window]
+[\-\-root]
+[\-\-delay \fInumber\fP]
+[\-\-speed \fInumber\fP]
+[\-\-scale \fInumber\fP]
+[\-\-fps]
+.SH DESCRIPTION
+Our investigation of the signal from the planet's surface brought us to
+what seems to be an alien beacon. Based on the rock formation around the
+beacon, it was probably left here millions of years ago.
+.SH OPTIONS
+.TP 8
+.B \-\-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-\-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-\-root
+Draw on the root window.
+.TP 8
+.B \-\-delay \fInumber\fP
+Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
+.TP 8
+.B \-\-speed \fInumber\fP
+Animation speed. 2.0 means twice as fast, 0.5 means half as fast.
+.TP 8
+.B \-\-scale \fInumber\fP
+Frame buffer resolution. 0.5 means halve the resolution for better
+performance but lower quality output. Default 1.0, full quality.
+.TP 8
+.B \-\-fps | \-\-no\-fps
+Whether to show a frames-per-second display at the bottom of the screen.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.TP 8
+.B XSCREENSAVER_WINDOW
+The window ID to use with \fI\-\-root\fP.

+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-\-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-\-root
+Draw on the root window.
+.TP 8
+.B \-\-delay \fInumber\fP
+Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
+.TP 8
+.B \-\-speed \fInumber\fP
+Animation speed. 2.0 means twice as fast, 0.5 means half as fast.
+.TP 8
+.B \-\-scale \fInumber\fP
+Frame buffer resolution. 0.5 means halve the resolution for better
+performance but lower quality output. Default 1.0, full quality.
+.TP 8
+.B \-\-fps | \-\-no\-fps
+Whether to show a frames-per-second display at the bottom of the screen.
+.SH ENVIRONMENT

+.SH DESCRIPTION
+Disc-based visualization of different frequencies next to each other.
+.SH OPTIONS
+.TP 8
+.B \-\-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-\-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-\-root
+Draw on the root window.
+.TP 8
+.B \-\-delay \fInumber\fP
+Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
+.TP 8
+.B \-\-speed \fInumber\fP
+Animation speed. 2.0 means twice as fast, 0.5 means half as fast.
+.TP 8
+.B \-\-scale \fInumber\fP
+Frame buffer resolution. 0.5 means halve the resolution for better
+performance but lower quality output. Default 1.0, full quality.
+.TP 8
+.B \-\-fps | \-\-no\-fps
+Whether to show a frames-per-second display at the bottom of the screen.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.

+ * documentation for any purpose is hereby granted without fee, provided that

+ * copyright notice and this permission notice appear in supporting
+ * documentation. No representations are made about the suitability of this
+ * software for any purpose. It is provided "as is" without express or
+ * implied warranty.
+ *
+ * Run arbitrary GLSL programs that use the shadertoy.com API.
+ * Usage:
+ *
+ * xshadertoy --program FILE.glsl
+ *
+ * xshadertoy --program-common FILE.glsl \
+ * --program0 FILE0.glsl \
+ * --program1 FILE1.glsl \
+ * --program2 FILE2.glsl \
+ * --program3 FILE3.glsl \
+ * --program4 FILE4.glsl \
+ * --speed 2.0 \
+ * --scale 0.5 \
+ * --automouse \
+ *
+ * It is not possible to have this program load the code directly from
+ * shadertoy.com due to their scraping countermeasures, so you must
+ * download the GLSL files manually. The "xshadertoy-download.pl"
+ * script makes that a little easier, but not much easier.
+ *
+ * Does not support texture or other input assets; the programs must
+ * be self-contained.
+ *
+ * Multi-pass rendering is supported, but only in the default order:
+ * e.g. program3 gets program2's output on iChannel2 and can't bind
+ * iChannel2 to a different pass instead. Likewise, self-access to
+ * previously-generated frames is not supported.
+ *
+ *
+ * LICENSING:
+ *
+ * The default license on shadertoy.com is "CC BY-NC-SA", and so the vast
+ * majority of uploads use that. However, that license, by prohibiting
+ * commercial use, is not an open source license, and is more restrictive
+ * than the MIT/BSD-style license used by the rest of XScreenSaver.
+ *
+ * For a Shadertoy program to be distributed with or within XScreenSaver,
+ * it must be licensed under a compatible license, such as: MIT, BSD,
+ * CC-BY, CC-BY-SA or CC0.
+ *
+ * Also: The Shadertoy community has a strong culture of remixing, so
+ * when evaluating the license terms of a program, any programs that
+ * it was derived from must also have compatible terms.
+ *
+ *
+ * CONTROL FLOW:
+ *
+ * The naming convention for Shadertoy-based XScreenSaver modules is
+ * that the GLSL files have the same basename as the hack itself,
+ * plus an optional suffix ("HACK-[c0-4].glsl"). Each gets its own
+ * config/HACK.xml and .man as usual.
+ *
+ * X11:
+ * /usr/libexec/xscreensaver/HACK is a bash script that invokes
+ * "xshadertoy" with the GLSL code on stdin. It uses "exec -a" so
+ * that argv0 / progname = "HACK" and progclass = "XShadertoy".
+ * Makefile.in rules build these via xshadertoy-compile.pl.
+ *
+ * macOS Cocoa:
+ * The HACK.saver target compiles xshadertoy.c and XScreenSaverView.c
+ * and includes the .glsl files as assets.
+ *
+ * As usual, XScreenSaverView compiles to class XScreenSaverHACKView,
+ * but it is also compiled with -DUSE_SHADERTOY=1 which causes it
+ * to use "xshadertoy_xscreensaver_function_table" instead of
+ * "HACK_xscreensaver_function_table". It then changes progclass
+ * from "XShadertoy" back to "HACK".
+ *
+ * This file, xshadertoy.c, searches in $BUNDLE_RESPATH (which is
+ * "HACK.saver/Contents/Resources/") for the .glsl files and loads
+ * them as normal files.
+ *
+ * iOS Cocoa:
+ * Same as macOS except that instead of -DUSE_SHADERTOY, the
+ * ios-function-table.m maps "xshadertoy_xscreensaver_function_table".
+ *
+ * Android:
+ * The .glsl files are copied into xscreensaver/assets/glsl/ in the
+ * APK by check-configs.pl. Similarly to iOS, function-table.h maps
+ * "xshadertoy_xscreensaver_function_table". This file loads them
+ * with android_read_asset_file() instead of with fopen().

+.SH DESCRIPTION
+Runs arbitrary GLSL programs that use the shadertoy.com API.
+.SH OPTIONS
+.TP 8
+.B \-\-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-\-window
+Draw on a newly-created window. This is the default.
+.TP 8
+.B \-\-root
+Draw on the root window.
+.TP 8
+.B \-\-delay \fInumber\fP
+Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
+.TP 8
+.B \-\-speed \fInumber\fP
+Animation speed. 2.0 means twice as fast, 0.5 means half as fast.
+.TP 8
+.B \-\-scale \fInumber\fP
+Frame buffer resolution. 0.5 means halve the resolution for better
+performance but lower quality output. Default 1.0, full quality.
+.TP 8
+.B \-\-program0 \fIfile\fP
+.TP 8
+.B \-\-program1 \fIfile\fP
+.TP 8
+.B \-\-program2 \fIfile\fP
+.TP 8
+.B \-\-program3 \fIfile\fP
+.TP 8
+.B \-\-program4 \fIfile\fP
+GLSL code, each as an input to the previous.
+.TP 8
+.B \-\-program\-common \fIfile\fP
+GLSL code to prepend to each program.
+.TP 8
+.B \-\-automouse | \-\-no\-automouse
+Whether to pretend to drag the mouse around sinusoidally. Default false.
+.TP 8
+.B \-\-automouse\-speed \fIratio\fP
+How fast. Default 1.0.
+.TP 8
+.B \-\-fps | \-\-no\-fps
+Whether to show a frames-per-second display at the bottom of the screen.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
+.TP 8
+.B XSCREENSAVER_WINDOW
+The window ID to use with \fI\-\-root\fP.

* Permission to use, copy, modify, distribute, and sell this software and its
* documentation. No representations are made about the suitability of this
* software for any purpose. It is provided "as is" without express or
* implied warranty.
+ *
+ * When configured --with-record-animation, each screenhack takes a
+ * "-record-animation DUR" arg that will cause it to run for exactly that
+ * many frames, and write a "progname.mp4" file into the current directory.
+ * "DUR" may be a number of frames, or a time specified as H:MM:SS, "N sec",
+ * etc. at 30 FPS.
+ *
+ * The MP4 file will be written at 30 FPS, and it is therefore assumed that
+ * each frame of the screenhack took 1/30th second to render and display,
+ * regardless of the --delay option, or how long it actually took; so using
+ * --delay 0 will speed up encoding.
+ *
+ * Likewise, any calls the saver makes to time(), double_time() or
+ * gettimeofday() will be falsified to maintain this timing illusion.
+ * Even if it takes 2 minutes to write out 30 seconds of video, the
+ * screenhack will only see the wall clock advance by 30 seconds.
+ *
+ * This is how I generate the videos for the XScreenSaver YouTube playlist:
+ * https://www.youtube.com/playlist?list=PLbe67PprBSpqM_-HU49fmIS8ncApw4i08
