ncursesw_bin.so: undefined symbol: set_menu_win

[JustAPerson]

Hi,

I just installed on Ubuntu 18.04

$ sudo apt install sup-mail
$ sup-mail
Traceback (most recent call last):
	5: from /usr/bin/sup-mail:6:in `<main>'
	4: from /usr/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'

I tried also installing the build dependencies (apt-get install build-essential libncursesw5-dev uuid-dev zlib1g-dev) but that didn't help either.

Has this been solved yet? I'm having the same issue now. I tried installing using both apt and gem, and they both threw such error.

Whatever gem or package you got this file from: /usr/lib/x86_64-linux-gnu/ruby/vendor_ruby/2.5.0/ncursesw_bin.so is the real problem. It appears not to be correctly built against the version of libncurses or libncursesw you have on your system.

In case it helps, on Fedora 32 with ncurses 6.1 that symbol is defined in libmenu.so and my copy of ncursesw_bin.so is linked against it:

Although the issue is with the downstream packaging, here is the workaround that I use in order to run sup-mail on Ubuntu 18.04 LTS (bionic).

I install the ncursesw gem myself, and then sup-mail runs fine after that.

# Install build prerequisites for gem ncursesw
sudo apt install \
    build-essential \
    patch \
    ruby-dev \
    zlib1g-dev \
    liblzma-dev \
    libncurses5-dev \
    lib32ncurses5-dev \
    libncursesw5-dev

# Install gem ncursesw
sudo gem install ncursesw

# Install and run sup-mail
# If sup-mail is already installed, then reinstallation is not required
sudo apt install sup-mail
sup-mail

Downstream bugs:

• Ubuntu Bug #1787763:
  ruby-ncurses is broken: try ruby -e 'require "ncurses"'
• Ubuntu Bug #1775673: ruby-ncurses is broken in ubuntu 18.04
• Debian Bug #892181: ruby-ncurses fails to load with Ruby 2.5

Bug in Ubuntu package ruby-ncurses, which sup-mail depends upon.

Workaround available: manually install ncursesw gem (see previous comment above).

Fixed downstream in Ubuntu.

To obtain fix, bionic-updates, update ruby-ncurses (fixed version: 1.4.9-1build3ubuntu0.18.04.1).
