How to Install The Ncursesw Development Libraries

Use ncursesw6 on mingw

That looks as if you downloaded one of the sample cross-compiled builds from the ncurses homepage. Those are configured assuming a typical MinGW configuration, with the DLLs in /bin, the headers under /include and the link-libraries in /lib.

It is possible to use that from another location, but you would have to modify the ncursesw6-config script to reflect the new location. Also, the DLLs have to be in some directory on your $PATH. If they are not, that may not interfere with linking, but will prevent the resulting programs from running.

In the script, there is a section like this:

prefix=""
exec_prefix="${prefix}"

bindir="${exec_prefix}/bin"
includedir="${prefix}/include"
libdir="${exec_prefix}/lib"
datarootdir="${prefix}/share"
datadir="${datarootdir}"
mandir="${datarootdir}/man"

Based on the illustration of your directory tree, you would want to change that first line to

prefix=/home/LNV/ncurses6_mingw64

and add

/home/LNV/ncurses6_mingw64/bin

to your PATH environment variable.

By the way, MinGW has a package for ncurses, which you might consider using...

Where do I put the -lncurses to properly link the ncurses library

Apple's bundled copy of ncurses (5.7) is configured for wide-character ncurses. For that platform (and perhaps a few others), the makefile could just use -lncurses.

But waddwnstr uses wchar_t parameters, which makes it a wide-character function. For the usual case, that is in the wide-character library, so you would use -lncursesw.

If you were using an add-on library (i.e., MacPorts or brew), that uses a symbolic link to allow either name to be used, to simplify porting.

Keeping things like this straight is generally done with configure scripts (to produce a correct makefile), so that your makefile would contain

LDFLAGS = -lncurses -lstdc++fs

or

LDFLAGS = -lncursesw -lstdc++fs

If both libraries were specified, the linker should complain about the duplicated symbols between the two libraries -- for most platforms other than MacOS.

When both libraries are available, the header files also are available, requiring some compiler (-I) options and/or source-modification to use the correct header (not just ncurses.h). Again, a configure script is the usual approach.

Add curses library to Visual Studio C++?

In a nutshell: you want Bill Gray's PDCurses. That fork is quite active. The "original" implementation is in
Bill McBrine's repo, with some activity going on. The two projects seem sadly to have diverged, though. The former has implemented a native Win32a GDI terminal window, while the latter only supports the native Windows console.

What you did is not how to use curses at all. What you have downloaded is source code, there are no binaries there at all - no .lib nor .dll files for any architecture. Not only that, but the source code can't be directly compiled either -- if you'd have added it to a C/C++ project, even on a Unix box, it wouldn't compile.

In order to compile, curses needs to have a configure script run, that generates some files, probably config.h, perhaps other source files, and makefiles.

Alas, all that is a moot point because curses is AFAIK a Unix library that really depends on Unix APIs being present. Any Windows ports are completely separate efforts.

Install Haskell terminfo in Windows

So I tried cabal install terminfo --extra-lib-dirs=/lib/ncursesw, but then I realized that cabal is a windows app, so I've also tried --extra-lib-dirs=c:/cygwin/lib/ncursesw

In the end, final solution is as follows:

1. Install Cygwin and ncursesw-devel package there
2. Run cygwin and configure GCC:
   $ export C_INCLUDE_PATH=/usr/include/ncursesw
3. Since C:\cygwin\usr\include\ncursesw\ncurses.h is a soft-reference in Cygwin, you should manually replace this file with curses.h from the same folder

4. From the same Cygwin terminal you can now start Cabal (it's a Windows program!):

   $ cabal install terminfo --extra-lib-dirs=c:/cygwin/lib --extra-include-dirs=c:/cygwin/usr/include/ncursesw --extra-include-dirs=c:/cygwin/usr/include

So, the library was installed. But when I try to actually use that function, ghc complains:

Loading package terminfo-0.3.2.5 ... linking ... ghc.exe: c:/cygwin/lib\libncursesw.a: unknown symbol `__imp____ctype_ptr__'

Ncurses static libraries to include with a C++ project

libncurses.a   - This is the C compatible library.
libncurses++.a - This is the C++ compatible library.
libncurses_g.a - This is the debug library.
libncurses_p.a - This is the profiling library.

If you want to find out if you can get by without using libncurses.a, you can rename the library and run a build of your application.

How to install ncurses on raspberry Pi?

To install the NCurses library on a Debian based machine you can issue the apt-get command below:

sudo apt-get install libncurses5-dev libncursesw5-dev 

This will install both the libncurses5-dev (for ncurses) and libncursesw5-dev (for ncursesw) on your machine.
