[gentoo-user] gdb build failure: tui/tui-win.o: undefined reference to symbol 'keypad'

[Grant Edwards]

This morning the build of gdb failed during a routine update:


  CXX    xml-builtin.o
  CXX    xml-support.o
  CXX    xml-syscall.o
  CXX    xml-tdesc.o
  CXX    init.o
  CXXLD  gdb

I've done some googling, and initially thought it might be due to the
fact that I had both ncurses:5 and ncurses:6 installed.  I uninstalled
:5 and did a revdep-rebuild (which found nothing to rebuild).  But gdb
still fails to build.

Any clues?
