1 CONFIGURE OPTIONS
2 General hint: if you get compile errors, then likely your configuration
3 hasn't been tested well. Either try with "--enable-everything" or use
4 the default configuration (i.e. no "--enable-xxx" or "--disable-xxx"
5 switches). Of course, you should always report when a combination
6 doesn't work, so it can be fixed. Marc Lehmann <rxvt@schmorp.de>.
7
8 All
9
10 --enable-everything
11 Add (or remove) support for all non-multichoice options listed in
12 "./configure --help", except for "--enable-assert" and
13 "--enable-256-color".
14
15 You can specify this and then disable options you do not like by
16 *following* this with the appropriate "--disable-..." arguments, or
17 you can start with a minimal configuration by specifying
18 "--disable-everything" and than adding just the "--enable-..."
19 arguments you want.
20
21 --enable-xft (default: on)
22 Add support for Xft (anti-aliased, among others) fonts. Xft fonts
23 are slower and require lots of memory, but as long as you don't use
24 them, you don't pay for them.
25
26 --enable-font-styles (default: on)
27 Add support for bold, *italic* and *bold italic* font styles. The
28 fonts can be set manually or automatically.
29
30 --with-codesets=CS,... (default: all)
31 Compile in support for additional codeset (encoding) groups ("eu",
32 "vn" are always compiled in, which includes most 8-bit character
33 sets). These codeset tables are used for driving X11 core fonts,
34 they are not required for Xft fonts, although having them compiled
35 in lets rxvt-unicode choose replacement fonts more intelligently.
36 Compiling them in will make your binary bigger (all of them together
37 cost about 700kB), but it doesn't increase memory usage unless you
38 use a font requiring one of these encodings.
39
40 all all available codeset groups
41 zh common chinese encodings
42 zh_ext rarely used but very big chinese encodings
43 jp common japanese encodings
44 jp_ext rarely used but big japanese encodings
45 kr korean encodings
46 --enable-xim (default: on)
47 Add support for XIM (X Input Method) protocol. This allows using
48 alternative input methods (e.g. kinput2) and will also correctly set
49 up the input for people using dead keys or compose keys.
50
51 --enable-unicode3 (default: off)
52 Recommended to stay off unless you really need a lot of non-BMP
53 characters.
54
55 Enable support for direct storage of unicode characters above 65535
56 (the basic multilingual page). This increases storage requirements
57 per character from 2 to 4 bytes. X11 fonts do not yet support these
58 extra characters, but Xft does.
59
60 Please note that rxvt-unicode can store and display unicode
61 characters above 65535 even without this flag, but the number of
62 such characters is limited to a few thousand (shared with combining
63 characters, see next switch).
64
65 --enable-combining (default: on)
66 Enable automatic composition of combining characters into composite
67 characters. This is required for proper viewing of text where
68 accents are encoded as separate unicode characters. This is done by
69 using precomposed characters when available or creating new
70 pseudo-characters when no precomposed form exists.
71
72 Without --enable-unicode3, the number of additional precomposed
73 characters is somewhat limited (the 6400 private use characters will
74 be (ab-)used). With --enable-unicode3, no practical limit exists.
75
76 This option will also enable storage (but not display) of characters
77 beyond plane 0 (>65535) when --enable-unicode3 was not specified.
78
79 The combining table also contains entries for arabic presentation
80 forms, but these are not currently used. Bug me if you want these to
81 be used (and tell me how these are to be used...).
82
83 --enable-fallback[=CLASS] (default: Rxvt)
84 When reading resource settings, also read settings for class CLASS.
85 To disable resource fallback use --disable-fallback.
86
87 --with-res-name=NAME (default: urxvt)
88 Use the given name as default application name when reading
89 resources. Specify --with-res-name=rxvt to replace rxvt.
90
91 --with-res-class=CLASS (default: URxvt)
92 Use the given class as default application class when reading
93 resources. Specify --with-res-class=Rxvt to replace rxvt.
94
95 --enable-pixbuf (default: on)
96 Add support for GDK-PixBuf to be used for background images. It adds
97 support for many file formats including JPG, PNG, TIFF, GIF, XPM,
98 BMP, ICO and TGA.
99
100 --enable-startup-notification (default: on)
101 Add support for freedesktop startup notifications. This allows
102 window managers to display some kind of progress indicator during
103 startup.
104
105 --enable-transparency (default: on)
106 Add support for using the root pixmap as background to simulate
107 transparency. Note that this feature depends on libXrender and on
108 the availability of the RENDER extension in the X server.
109
110 --enable-fading (default: on)
111 Add support for fading the text when focus is lost.
112
113 --enable-rxvt-scroll (default: on)
114 Add support for the original rxvt scrollbar.
115
116 --enable-next-scroll (default: on)
117 Add support for a NeXT-like scrollbar.
118
119 --enable-xterm-scroll (default: on)
120 Add support for an Xterm-like scrollbar.
121
122 --disable-backspace-key
123 Removes any handling of the backspace key by us - let the X server
124 do it.
125
126 --disable-delete-key
127 Removes any handling of the delete key by us - let the X server do
128 it.
129
130 --disable-resources
131 Removes any support for resource checking.
132
133 --disable-swapscreen
134 Remove support for secondary/swap screen.
135
136 --enable-frills (default: on)
137 Add support for many small features that are not essential but nice
138 to have. Normally you want this, but for very small binaries you may
139 want to disable this.
140
141 A non-exhaustive list of features enabled by "--enable-frills"
142 (possibly in combination with other switches) is:
143
144 MWM-hints
145 EWMH-hints (pid, utf8 names) and protocols (ping)
146 urgency hint
147 separate underline colour (-underlineColor)
148 settable border widths and borderless switch (-w, -b, -bl)
149 visual depth selection (-depth)
150 settable extra linespacing (-lsp)
151 iso-14755 5.1 (basic) support
152 tripleclickwords (-tcw)
153 settable insecure mode (-insecure)
154 keysym remapping support
155 cursor blinking and underline cursor (-bc, -uc)
156 XEmbed support (-embed)
157 user-pty (-pty-fd)
158 hold on exit (-hold)
159 compile in built-in block graphics
160 skip builtin block graphics (-sbg)
161 separate highlight colour (-highlightColor, -highlightTextColor)
162 focus reporting mode (1004).
163 extended mouse reporting modes (1005, 1006 and 1015).
164 visual selection via -visual and -depth.
165 systemd socket activation
166 selectable rewrapmode
167 bracketed paste mode
168
169 It also enables some non-essential features otherwise disabled, such
170 as:
171
172 some round-trip time optimisations
173 nearest colour allocation on pseudocolor screens
174 UTF8_STRING support for selection
175 sgr modes 90..97 and 100..107
176 backindex and forwardindex escape sequences
177 view change/zero scrollback escape sequences
178 locale switching escape sequence
179 window op and some xterm/OSC escape sequences
180 rectangular selections
181 trailing space removal for selections
182 verbose X error handling
183
184 --enable-iso14755 (default: on)
185 Enable extended ISO 14755 support (see urxvt(1)). Basic support
186 (section 5.1) is enabled by "--enable-frills", while support for
187 5.2, 5.3 and 5.4 is enabled with this switch.
188
189 --enable-keepscrolling (default: on)
190 Add support for continual scrolling of the display when you hold the
191 mouse button down on a scrollbar arrow.
192
193 --enable-selectionscrolling (default: on)
194 Add support for scrolling when the selection moves to the top or
195 bottom of the screen.
196
197 --enable-mousewheel (default: on)
198 Add support for scrolling via mouse wheel or buttons 4 & 5.
199
200 --enable-slipwheeling (default: on)
201 Add support for continual scrolling (using the mouse wheel as an
202 accelerator) while the control key is held down. This option
203 requires --enable-mousewheel to also be specified.
204
205 --enable-smart-resize (default: off)
206 Add smart growth/shrink behaviour when resizing. This should keep
207 the window corner which is closest to a corner of the screen in a
208 fixed position.
209
210 --enable-text-blink (default: on)
211 Add support for blinking text.
212
213 --enable-pointer-blank (default: on)
214 Add support to have the pointer disappear when typing or inactive.
215
216 --enable-perl (default: on)
217 Enable an embedded perl interpreter. See the urxvtperl(3) manpage
218 for more info on this feature, or the files in src/perl/ for the
219 extensions that are installed by default. The perl interpreter that
220 is used can be specified via the "PERL" environment variable when
221 running configure. Even when compiled in, perl will *not* be
222 initialised when all extensions have been disabled "-pe ""
223 --perl-ext-common """, so it should be safe to enable from a
224 resource standpoint.
225
226 --enable-assert (default: off)
227 Enables the assertions in the code, normally disabled. This switch
228 is only useful when developing rxvt-unicode.
229
230 --enable-256-color (default: off)
231 Force use of so-called 256 colour mode, to work around buggy
232 applications that do not support termcap/terminfo, or simply improve
233 support for applications hardcoding the xterm 256 colour table.
234
235 This switch breaks termcap/terminfo compatibility to
236 "TERM=rxvt-unicode", and consequently sets "TERM" to
237 "rxvt-unicode-256color" by default (doc/etc/ contains
238 termcap/terminfo definitions for both).
239
240 It also results in higher memory usage and can slow down urxvt
241 dramatically when more than six fonts are in use by a terminal
242 instance.
243
244 --with-name=NAME (default: urxvt)
245 Set the basename for the installed binaries, resulting in "urxvt",
246 "urxvtd" etc.). Specify "--with-name=rxvt" to replace with "rxvt".
247
248 --with-term=NAME (default: rxvt-unicode)
249 Sets the default "TERM" value that urxvt sets. The default is either
250 "rxvt-unicode" or "rxvt-unicode-256color", as appropriate.
251
252 --with-terminfo=PATH
253 If set, urxvt will set the environment variable "TERMINFO" to the
254 given PATH, which can be useful as a last resort if installing the
255 terminfo entries system-wide is not possible.
256
257 --with-x
258 Use the X Window System (pretty much default, eh?).
259
