undefined symbol: UP

[Fabrice BAUZAC]

Hello,

I'm trying to build and install readline 8.1 from source, but it looks
like the generated library refers to some symbol "UP" which is not
found, making the library unusable:

  $ LD_PRELOAD=$PWD/shlib/libreadline.so.8.1 /bin/true
  /bin/true: symbol lookup error:
  /tmp/readline-8.1/shlib/libreadline.so.8.1: undefined symbol: UP
  
  objdump -T /home/noon/gsrc/lib/libreadline.so.8
  0000000000000000      D  *UND*        0000000000000000              UP
  
  objdump -p /home/noon/gsrc/lib/libreadline.so.8
    NEEDED               libc.so.6

The libreadline I have on Debian does not have this issue, because it
has a DT_NEEDED on libtinfo which provides this symbol:

  objdump -T /lib/x86_64-linux-gnu/libreadline.so.8
  0000000000000000      DO *UND*        0000000000000000  
NCURSES6_TINFO_5.0.19991023 UP

  objdump -p /lib/x86_64-linux-gnu/libreadline.so.8
    NEEDED               libtinfo.so.6
    NEEDED               libc.so.6

  /lib/x86_64-linux-gnu/libtinfo.so.6
  000000000002e948 g    DO .bss 0000000000000008  NCURSES6_TINFO_5.0.19991023 UP

What's wrong?

Note that in my build I do not use ncurses but termcap; but shouldn't it
work nevertheless? --

  checking which library has the termcap functions... using libtermcap

For the record, here is the full output of the configure script.
