ncurses and ncursesw

[Dennis Veatch]

The way ncursesw installs or rather does not install all the things it does is
not sufficient to support other modules requiring a wide terminal. Two I am 
aware of are; cdw-0.6.0 (not in moonbase atm) and the ncurses version of 
x3270. I think there may be a few others but do not recall atm.

I have done some poking around with this module and came up with this;

(

  if [ $WITH_DEBUG == "y" ]; then
    OPTS+=" --with-debug"
  else
    OPTS+=" --without-debug"
  fi;

  if [ $WITH_PROFILING == "y" ]; then
    OPTS+=" --with-profile"
  else
    OPTS+=" --without-profile"
  fi;

# Seems that ncurses-5.5 has problems with garbage in /usr/share/terminfo
# Note: ncurses-5.5 also has all the "screen" files for terminfo, so no 
recompile is needed
  rm -rf /usr/share/terminfo  &&

# ************************ WARNING *************************
# DO NOT MESS WITH THE CONFIGURE STUFF here unless you
# really know what you're doing! We chose the lib location
# specifically so we could link ncurses to bash which is 
# needed at init time! If you move it you could break your 
# system!

The second build just runs with widec and installs the needed headers in 
/usr/include/ncursesw. Attached are some install logs from a "non-wide" 
ncurses and one from the above BUILD. The gist is this; 

1. all wide versions of libs are append with a "w" such as libmenuw.so while 
the libmenu.so remains.

2, all wide headers are placed in include/ncursesw to avoid some conflicts in 
naming conventions with some of the same header names needed by non-wide and 
wide.

Before recompiling any modules the machine was rebooted and all is well. I 
then recompiled a few modules such as; grub, screen, samba, cdw-0.6.0, NVIDIA-
beta and a few others with no issues.

I have a foggy recollection from some years back when cmak wanted ncursesw. I 
do not recall the reasons for its denial and find the addition of the nucrsesw 
modules a bit odd. If we intend to make such available then we should 
correctly install the needed libs/headers to support wide.
