Janet,

I am trying to use the readline library on cygwin-x86 with EPICS 3.14.7. 

It looks to me like there are 2 problems in the configure/os directory. 

1) CONFIG.Common.cygwin-x86 contains the line: 
LDLIBS_READLINE = -lcygreadline5 -lcygcurses7 

But recent versions of readline on cygwin don't have a library called cygreadline5, or cygcurses7, they just have a libraries called readline and curses. 

$ ls -l /usr/lib/*readline* /usr/lib/*curses*
lrwxrwxrwx  1 epics mkgroup-l-d     12 Oct 12 17:40 /usr/lib/libcurses.a -> libncurses.a
lrwxrwxrwx  1 epics mkgroup-l-d     16 Oct 12 17:40 /usr/lib/libcurses.dll.a -> libncurses.dll.a
-rwxr-x---+ 1 epics mkgroup-l-d 540990 Sep 28 21:16 /usr/lib/libncurses++.a
-rwxr-x---+ 1 epics mkgroup-l-d 171170 Sep 28 21:16 /usr/lib/libncurses++.dll.a
-rwxr-x---+ 1 epics mkgroup-l-d    887 Sep 28 21:16 /usr/lib/libncurses++.la
-rwxr-x---+ 1 epics mkgroup-l-d 396098 Sep 28 21:14 /usr/lib/libncurses.a
-rwxr-x---+ 1 epics mkgroup-l-d 280186 Sep 28 21:14 /usr/lib/libncurses.dll.a
-rwxr-x---+ 1 epics mkgroup-l-d    793 Sep 28 21:16 /usr/lib/libncurses.la
-rwxr-x---+ 1 epics mkgroup-l-d 264080 Jul 28 22:58 /usr/lib/libreadline.a
-rwxr-x---+ 1 epics mkgroup-l-d 345644 Jul 28 22:58 /usr/lib/libreadline.dll.a

2) There is no definition of COMMANDLINE_LIBRARY, commented or uncommented, in any of the CONFIG files for cygwin-x86. 

I fixed both of these problems by creating a new file CONFIG.Common.cygwin-x86 that contains the lines: 
COMMANDLINE_LIBRARY = READLINE
LDLIBS_READLINE = -lreadline -lcurses

Once I do that, applications I build have command line editing.

Is this the correct thing to do?

Thanks,
Mark
