rake error on Ubuntu 14.04

Though @kzhd15med3t said that an error that I pointed out yesterday was mended, an error happened today too. I paste the log of rake.

ueda@remote:~/rumin$ rake
sh ./mruby.sh

... and this is the error on Mac obtained just now. I think that rake does not find -lncursesw as I have taught this problem yesterday. But it will be very good when this problem is removed and someone never meets the same problem.

Thank you.

Thank you for your contribution.
At the first comment, the problem was solved to install package which is ruby-dev on my environment. Please try.
At the second comment, please install ncurses 5.9 with --enable-widec option.
http://ftp.gnu.org/pub/gnu/ncurses/

Finally, we are now talking about how to solve dependency in install phase.

[ryuichiueda]

mmm... not yet in my Ubuntu. It will be a path problem and should be solved in Rakefile.

ueda@remote:~/rumin$ sudo apt-get install ruby-dev
ueda@remote:~/rumin$ sudo apt-get install bison
ueda@remote:~/rumin$ sudo apt-get install libyaml-dev
ueda@remote:~/rumin$ wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-5.9.tar.gz
ueda@remote:~/rumin$ tar zxvf ncurses-5.9.tar.gz 
ueda@remote:~/rumin$ cd ncurses-5.9/
ueda@remote:~/rumin/ncurses-5.9$ ./configure 
ueda@remote:~/rumin/ncurses-5.9$ sudo make install
ueda@remote:~/rumin/ncurses-5.9$ cd ..
ueda@remote:~/rumin$ rake
...
/usr/bin/ld: -lncursesw が見つかりません

[kzhd15med3gh]

Please replace the configure script's option like this.
./configure --enable-widec

[ryuichiueda]

OK, I'll try it tomorrow. Anyway, it should be written anywhere in a document. Otherwise, you will lose enthusiasts who spread your product across the world.

I wish I could contribute through a pull request, but...
I'm sorry.
