Follow-up to my problems
(linking to ncurses failing)
with system info & how I reinstalled ncurses
Includes (#1) system info, (#2) how I reinstalled ncurses again, (#3)
linker errors
(#4) note on gdb crashing with statically linked version (same problem I
suspect)
#1) Relevant System Info (I hope)

#2) How I Reinstalled ncurses
*************************
re:
http://cygwin.com/ml/cygwin-announce/2001/msg00124.html
(The page doesn't really say what to do if you think your
setup is broken, so I'm extrapolating that the safest thing
is to remove all affected packages & reinstall as per
the page. So I just now repeated what I did before,
documenting it this time, partly lest I made any mistake
last time, partly so I submit an explanation here.)
-1) I removed libncurses5 (5.2-1), libncurses6 (5.2-2),
& ncurses (5.2-7) & terminfo (5.2-1)
-2) I installed only ncurses (5.2-7)
-3) I installed libncurses (5.2-1), libncurses 6 (5.2-2),
and terminfo (5.2-1).
I still don't have /usr/include/ncurses/ncurses_dll.h,
(although maybe this is ok ?)
and my link still fails.
So I'm repeating my mistake, or I still have the configuration
problem, or ... ?
(PS: We can actually build successfully if we use
-DBROKEN_LINKER -static
so perhaps this suggests my bintools is out-of-date ?)
#3) Linker Error
********************
Oh, and sorry that I omitted the following (that was
another mistake I made).
My "failing" linker error looks like so:
... undefined reference to `acs_map'
... undefined reference to `acs_map'
... undefined reference to `acs_map'
... undefined reference to `acs_map'
... undefined reference to `acs_map'
... more undefined references to `acs_map' follow
collect2: ld returned 1 exit status
make: *** [llines] Error 1
#4) gdb problem (looks suspiciously like the same problem)
*****************************
PS:
If I build with -static and -DBROKEN_LINKER
I can run ok, unless I try to run thru gdb, in
which case I segfault. Stepping thru, I find the
segfault is at the first reference to COLS.
I #defined COLS & LINES as a temporary fix to see if
I could then use gdb, but then it segfaults at the
first reference to acs_map. At that point I decided
I might be on the wrong road :)
