I wonder which setup program that was, and how your environment is set up?

That message is from a native Windows port of bc, installed under/by 
Mingw/64, Msys/2, Chocolatey or some other native Windows port installer 
that does not handle library dependencies. You would have to install 
that environment's readline library using their setup program.

If you have installed Cygwin, you must start it using (perhaps some 
minor variation of) the provided shortcuts, command files, or scripts, 
and ensure the Cygwin path is set with Cygwin /usr/bin/ near the start, 
possibly preceded by your own local script directory/-ies: e.g.

	$HOME/bin:/usr/local/bin:/usr/bin

Re: this must be a common problem, but repeated searching is not finding an answer

Running bc by itself gave the same error message.

Just in case that bc was not part of cygwin, I deleted it and reran the 
install.  It did not seem to have bc listed as a component to install.  
My PATH is now:

/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Windows/System32/OpenSSH:/cygdrive/c/Program 
Files/NVIDIA Corporation/NVIDIA NvDLISR:/cygdrive/c/Program Files 
(x86)/Emacs/i686/bin:.:$HOME/bin:/cygdrive/c/usr/bin:/cygdrive/c/Users/clayt/AppData/Local/Microsoft/WindowsApps

If bc is not in cygwin, what should I use to get a version for Windows?  
Or do I need to roll my own?

bc is available in Cygwin.

Note that Cygwin is not a single thing, but a library that provides a pretty
faithful mapping from POSIX library calls to Windows ones, PLUS a large number
of packages, individually installable (modulo their dependencies on one
another), of Posix compatible tools recompiled for Cygwin (often with patches
to make them compile properly under Cygwin).

bc is (logically enough) in the bc package.

Cygwin Setup - Select Packages says there are no packages to install or 
update.  No is there a bc executable under \cygwin

You have to select packages explicitly.

It does not just blindly install all of them - that's a lot of stuff,
and for various reasons not a great idea.  Install what you need.

I installed everything, but that does not seem to include bc.

When you run the Cygwin Net Release Setup Program, a.k.a. Setup, and
after clicking Next a number of times, you should come to a
full-screen page titled, "Select Packages".  In the upper left
corner of that page is a drop-down list labelled View and with
a default setting of Pending.  Change that setting to Full.

To the right of the View selection is the Search box.  Enter into
that box just the two letters

    bc

You should see at the top of the resulting list of packages the bc
package.  The New column (the third column) for the bc package
probably says Skip.  Click on the arrow in that field and select the
newest package number, which should be 1.06.95-2.

At the bottom of that page, click on Next and follow whatever
instructions follow.  That should install bc as /usr/bin/bc.

HTH,
Gary

So you went through and explicitly asked for each package?
If you did, then that would include bc, since it is one of
the packages.  I'm now confused.  How did you request
"everything"?

With a note that actually selecting every package in Cygwin repositories
and installing them would be huge, and take a really long time, even on
fiber with no bandwidth caps.

Thanks to all. I will go back and make sure I have selected bc as well.    I clearly did not understand the selection mechanism.

Thanks.  bc is now installed.

Cygwin's bc does not depend on this library and it would not give you
this error message either.  I suggest you try "/usr/bin/bc" from a
Cygwin shell and then think about what you want to have your PATH look
like.

I installed everything from the setup program, but executing bc gives 
"The code execution cannot proceed because readline4.dll was not found.  
Reinstalling the program may fix this problem."  From where do I get 
readline4.dll?
