unable to install and/or use rbcurse #11

I am new to ruby gem any help is welcome. I try to use rbcurse under: ubuntu 11.10 Desktop 64 bit ruby 1.8.7-352-2 # os default rubygems 1.7.2-1 # os default

gem install --bindir ~/bin --install-dir ~/.gem/ruby/1.8 rbcurse # installed successfully into .../1.8/gems the following folders: -> ffi-1.0.11, ffi-locale-1.0.1, ffi-ncurses-0.4.0, rbcurse-1.5.0, rbcurse-core-0.0.3

ruby abasiclist.rb # results in error_ abasiclist.rc:1:in `require': no such file to load -- rbcurse/core/util/app (LoadError)

RUBYLIB=find ~/.gem -name lib -type d | tr "\012" ":" ruby abasiclist.rb # results in: ./.gem/ruby/1.8gem/ffi-1.0.11/lib/ffo/library.rb:121:in `ffi_lib': Could no open library 'libncurses.so':/usr/lib/libncurses.so: file too short. (LoadError)

Content of /lib/ncurses.so: INPUT(libncurses.so.5 -ltinfo)

This seems to be standard. Some other users have reported this, too.

Anyway someone said, that the could fix this problem with sudo ln -s /lib/libncurses.so.5 /lib/ncurses.so # which could give other problems... but i have no better idea...

RUBYLIB=find ~/.gem -name lib -type d | tr "\012" ":" ruby abasiclist.rb # new result: ./.gem/ruby/1.8/gems/rbcurse-core-0.0.3/lib/rbcurse/core/widgets/rwidget.rb:33: uninitialized constant BOLD (NameError)

I don't known what BOLD ||= FFI::NCurses::A_BOLD means but if i remove the "||" it goes to the next line.. if i remove it from all 4 lines and start again i receive: ./.gem/ruby/1.8/gems/rbcurse-core-0.0.3/lib/rbcurse/core/util/widgetshortcuts.rb:96:in def_widget': undefineddowncase' for :Button:Symbol) noMethodError)

i have seen a discussion about 1 year ago where you talked to someone about the sense for rbcurse theses days. Let me say a few words: I have a blind friend and he has a braille terminal which can display 80 characters in one line at once. He works 100% under Linux console and this is perfect since all applications use it exactly. He uses mutt. moc and vi. Some applications don't show the cursor or have the cursor at a secific line regardless of the focus which is a problem. In moc you can enable the cursor and it works fine. I search for a framework to write programs for him. In my opinion you have a really great framework and you should work for it to go into debian/ubuntu - this would help :-).

Thanks for your work and any help!

Kind regards Michael

The first step is to see if ncurses is installed correctly. Are the ncurses samples running correctly?

Then please check if ffi-ncurses is running by running its examples. Usually once ffi is running fine, then the rbcurse examples run fine too. The only issue then is that rbcurse examples log to log files and need write priviileges where they are running.
