How to install Ncurses/Terminfo on your system
---------------------------------------------------------------------
NOTE: You must have installed the terminfo database, or set the
environment variable $TERMINFO to point to a SVr4-compatible terminfo
database before running the test programs. Not all vendors' terminfo
- databases are SVr4-compatible, but most seem to be. Exceptions include
- DEC's Digital Unix (formerly known as OSF/1).
+ databases are SVr4-compatible, but most seem to be.
+
+ It is possible to configure ncurses to use other terminfo database formats.
+ A few are provided as examples in the include-directory (see --with-caps).
If you run the test programs WITHOUT installing terminfo, ncurses may
read the termcap file and cache that in $HOME/.terminfo, which will
thereafter be used instead of the terminfo database. See the comments
on "--enable-getcap-cache", to see why this is a Bad Thing.

The ncurses program is designed specifically to test the ncurses library.
You can use it to verify that the screen highlights work correctly, that
cursor addressing and window scrolling works OK, etc.

The terminfo(5) manual page must be preprocessed with tbl(1) before
a screen, since (even after calling endwin()), it must be available
for use in the next call to refresh(). There are also chunks of
memory held for performance reasons. That makes it hard to analyze

+ the remainder and then exit. The ncurses utility and test programs
+ use this feature, e.g., via the ExitProgram() macro.
+
+ Because this lies outside of the library's intended usage, it is not
+ normally considered part of the ABI. If there were some (as yet
+ unplanned) extension which frees memory in a manner that would let the
+ library resume and reallocate memory, then that would not use a "_nc_"
+ prefix.
--disable-lp64
The header files will ignore use of the _LP64 symbol to make chtype
list documented in X/Open. ncurses provides varargs support for this
function. Use --disable-tparm-varargs to disable this support.
+ --disable-wattr-macros
+ The 6.0 ABI adds support for extended colors and for extended mouse.
+ The former is a noticeable problem when developers inadvertantly
+ compile using the ncurses6 header files and link with an ncurses5
+ library, because the wattr* macros use a new field in the WINDOW
+ structure. These macros are used in several applications.
+
+ Since ncurses provides an actual function for each of these macros,
+ suppressing them from the curses.h header allows the ncurses5 libraries
+ to be used in most applications.
+
+ NOTE: The extended colors also are used in the cchar_t structure, but
+ fewer applications use that.
+
+ NOTE: This workaround does not help with mismatches in the ncurses
+ mouse version. The extended mouse feature uses one less fewer bit for
+ each button, so that only the first button will work as expected with
+ a mismatch between header and library. Again, most applications will
+ work, since most use only the first button.
+
--enable-assertions
For testing, compile-in assertion code. This is used only for a few
places where ncurses cannot easily recover by returning an error code.
compatible with libncursesw 5.4. None of the interfaces change, but
applications which have mouse mask mmask_t's must be recompiled.
+ --enable-ext-putwin
+ Modify the file-format written by putwin() to use printable text rather
+ than binary files, allowing getwin() to read screen dumps written by
+ differently-configured ncurses libraries. The extended getwin() can
+ still read binary screen dumps from the "same" configuration of
+ ncurses. This does not change the ABI (the binary interface seen by
+ calling applications).
+
--enable-getcap
Use the 4.4BSD getcap code if available, or a bundled version of it to
fetch termcap entries. Entries read in this way cannot use (make
terminfo entries. This is the default, unless you have disabled the
extended functions.

+ --enable-opaque-panel
+ Define symbol in curses.h which controls whether some library

+ is overridden by the --enable-reentrant option.
+
--enable-pc-files
If pkg-config is found (see --with-pkg-config), generate ".pc" files
for each of the libraries, and install them in pkg-config's library

--with-versioned-syms[=XXX]
The Solaris, GNU and reportedly some other linkers (ld) accept a
"--version-script" option which tells the linker to annotate the

+ several builds, some symbols will be listed in the the ".map" files
+ that do not happen to be present in one configuration or another.
+
+ The sample ".map" (and ".sym") files are generated using a set of
+ scripts which build several configurations for each release version,
+ checking to see which of the "_nc_" symbols can be made local. In
+ addition to the ncurses libraries and programs, the symbols used
+ by the "tack" program before version 1.08 are made global.
+
+ These sample ".map" files will not cover all possible combinations.
+ In some cases, e.g., when using the --with-weak-symbols option, you

+ value.

COMPATIBILITY WITH OLDER VERSIONS OF NCURSES:
--------------------------------------------
- Because ncurses implements the X/Open Curses Specification, its interface
- is fairly stable. That does not mean the interface does not change.
- Changes are made to the documented interfaces when we find differences
- between ncurses and X/Open or implementations which they certify (such as
- Solaris). We add extensions to those interfaces to solve problems not
- addressed by the original curses design, but those must not conflict with
- the X/Open documentation.
