Emacs looks at the +"Co" capability for the terminal to find out how many colors are +supported; it should be non-zero to activate the color support within +Emacs. (Most color terminals support 8 or 16 colors.) If your system +uses terminfo, the name of the capability equivalent to "Co" is +"colors". + +In addition to the "Co" capability, Emacs needs the "op" (for +``original pair'') capability, which tells how to switch the terminal +back to the default foreground and background colors. Emacs will not +use colors if this capability is not defined. If your terminal entry +doesn't provide such a capability, try using the ANSI standard escape +sequence \E[00m (that is, define a new termcap/terminfo entry and make +it use your current terminal's entry plus \E[00m for the "op" +capability). + +Finally, the "NC" capability (terminfo name: "ncv") tells Emacs which +attributes cannot be used with colors. Setting this capability +incorrectly might have the effect of disabling colors; try setting +this capability to `0' (zero) and see if that helps. + +Emacs uses the database entry for the terminal whose name is the value +of the environment variable TERM. With `xterm', a common terminal +entry that supports color is `xterm-color', so setting TERM's value to +`xterm-color' might activate the color support on an xterm-compatible +emulator. + +Some modes do not use colors unless you turn on the Font-lock mode. +Some people have long ago set their `~/.emacs' files to turn on +Font-lock on X only, so they won't see colors on a tty. The +recommended way of turning on Font-lock is by typing "M-x +global-font-lock-mode RET" or by customizing the variable +`global-font-lock-mode'. + +* Problems in Emacs built with LessTif. + +The problems seem to depend on the version of LessTif and the Motif +emulation for which it is set up. + +Only the Motif 1.2 emulation seems to be stable enough in LessTif. +Lesstif 0.92-17's Motif 1.2 emulation seems to work okay on FreeBSD. +On GNU/Linux systems, lesstif-0.92.6 configured with "./configure +--enable-build-12 --enable-default-12" is reported to be the most +successful. The binary GNU/Linux package +lesstif-devel-0.92.0-1.i386.rpm was reported to have problems with +menu placement. + +On some systems, even with Motif 1.2 emulation, Emacs occasionally +locks up, grabbing all mouse and keyboard events. We still don't know +what causes these problems; they are not reproducible by Emacs +developers. + +* Known problems with the MS-Windows port of Emacs 21.1. + +Emacs 21.1 built for MS-Windows doesn't support images, the tool bar, +and tooltips. Support for these will be added in future versions. + +There are problems with display if the variable `redisplay-dont-pause' +is set to nil (w32-win.el sets it to t by default, to avoid these +problems). The problems include: + + . No redisplay as long as help echo is displayed in the echo area, + e.g. if the mouse is on a mouse-sensitive part of the mode line. + + . When the mode line is dragged with the mouse, multiple copies of the + mode line are left behind, until the mouse button is released and + the next input event occurs. + + . Window contents are not updated when text is selected by dragging + the mouse, and the mouse is dragged below the bottom line of the + window. When the mouse button is released, the window display is + correctly updated. + +Again, these problems only occur if `redisplay-dont-pause' is nil. + +Emacs can sometimes abort when non-ASCII text, possibly with null +characters, is copied and pasted into a buffer. + +An inactive cursor remains in an active window after the Windows +Manager driven switch of the focus, until a key is pressed. + +Windows 2000 input methods are not recognized by Emacs (as of v21.1). +These input methods cause the keyboard to send characters encoded in +the appropriate coding system (e.g., ISO 8859-1 for Latin-1 +characters, ISO 8859-8 for Hebrew characters, etc.). To make this +work, set the keyboard coding system to the appropriate value after +you activate the Windows input method. For example, if you activate +the Hebrew input method, type "C-x RET k iso-8859-8 RET". (Emacs +ought to recognize the Windows language-change event and set up the +appropriate keyboard encoding automatically, but it doesn't do that +yet.) + +Multilingual text put into the Windows 2000 clipboard by Windows +applications cannot be safely pasted into Emacs (as of v21.1). This +is because Windows 2000 uses Unicode to represent multilingual text, +but Emacs does not yet support Unicode well enough to decode it. This +means that Emacs can only interchange non-ASCII text with other +Windows 2000 programs if the characters are in the system codepage. +Reportedly, a partial solution is to install the Mule-UCS package and +set selection-coding-system to utf-16-le-dos. + +* The `configure' script doesn't find the jpeg library. + +This can happen because the linker by default only looks for shared +libraries, but jpeg distribution by default doesn't build and doesn't +install a shared version of the library, `libjpeg.so'. One system +where this is known to happen is Compaq OSF/1 (`Tru64'), but it +probably isn't limited to that system. + +You can configure the jpeg library with the `--enable-shared' option +and then rebuild libjpeg. This produces a shared version of libjpeg, +which you need to install. Finally, rerun the Emacs configure script, +which should now find the jpeg library. Alternatively, modify the +generated src/Makefile to link the .a file explicitly. + +(If you need the static version of the jpeg library as well, configure +libjpeg with both `--enable-static' and `--enable-shared' options.) + +* Building Emacs over NFS fails with ``Text file busy''. + +This was reported to happen when building Emacs on a GNU/Linux system +(RedHat Linux 6.2) using a build directory automounted from Solaris +(SunOS 5.6) file server, but it might not be limited to that +configuration alone. Presumably, the NFS server doesn't commit the +files' data to disk quickly enough, and the Emacs executable file is +left ``busy'' for several seconds after Emacs has finished dumping +itself. This causes the subsequent commands which invoke the dumped +Emacs excutable to fail with the above message. + +In some of these cases, a time skew between the NFS server and the +machine where Emacs is built is detected and reported by GNU Make +(it says that some of the files have modification time in the future). +This might be a symptom of NFS-related problems. + +If the NFS server runs on Solaris, apply the Solaris patch 105379-05 +(Sunos 5.6: /kernel/misc/nfssrv patch). If that doesn't work, or if +you have a different version of the OS or the NFS server, you can +force the NFS server to use 1KB blocks, which was reported to fix the +problem albeit at a price of slowing down file I/O. You can force 1KB +blocks by specifying the "-o rsize=1024,wsize=1024" options to the +`mount' command, or by adding ",rsize=1024,wsize=1024" to the mount +options in the appropriate system configuration file, such as +`/etc/auto.home'. + +Alternatively, when Make fails due to this problem, you could wait for +a few seconds and then invoke Make again.
