The most common have been +termcap, which is now largely outmoded, and curses, which supersedes +termcap and typically contains the same features as well as others. +configure will search for an appropriate library; the default search order +is "tinfo termcap ncurses curses" except on HP-UX and Solaris where it is +"Hcurses ncurses curses termcap". Note that even though termcap is usually +searched first zsh tries to make features from curses available and if the +curses library contains both curses and termcap features, as is normal, +the curses variant is used. ncurses is a newer version of curses +and tinfo is related to it. + +On some systems a suitable development package with a name such as +curses-devel or ncurses-devel needs to be installed before zsh can +be compiled. This is likely to be contained on any installation media, +or available for download. It is highly unlikely that you will need to +compile this from scratch. + +You can tell configure which libraries to search by passing an +argument via --with-term-lib. This takes a space-separated list +of libraries to try as its argument, so the default is equivalent to +--with-term-lib="tinfo termcap ncurses curses". It replaces the +old option --with-curses-terminfo, which altered the search order but +didn't allow an explicit search list to be passed. + Memory Routines --------------- @@ -34,6 +34,10 @@ Possible incompatibilities Since 4.2: +The configuration option --with-curses-terminfo has been replaced +by the option --with-term-lib="LIBS" where LIBS is a space-separated +list of libraries to search for termcap and curses features. + The option SH_WORD_SPLIT, used in Bourne/Korn/Posix shell compatibility mode, has been made more like other shells in the case of substitutions of the form ${1+"$@"} (a common trick used to work around problems in older diff --git a/configure.ac b/configure.ac index bb50986d5..215b48f04 100644 --- a/configure.ac +++ b/configure.ac @@ -641,12 +641,11 @@ dnl SYSV-derived systems.
