Problems compiling

[cinus80]

Dear All,
I am trying to compile a research program to do protest event analysis, but when I run 'make' i obtain an extremely long list of errors, which finishes in this way

modify.cp:(.text+0x12bd): undefined reference to `waddnstr'
modify.cp:(.te:(t+0x12c2): undefined reference to `stdscr'
modify.cp:(.text+0x12d2): undefined reference to `waddch'
modify.cp:(.text+0x140b): undefined reference to `stdscr'
modify.cp:(.text+0x141b): undefined reference to `waddch'
modify.o: In function `ModifyClass::setupChange()':
modify.cp:(.text+0x14fc): undefined reference to `stdscr'
modify.cp:(.text+0x1514): undefined reference to `whline'
modify.cp:(.text+0x153b): undefined reference to `move'
collect2: ld returned 1 exit status

I have seen in other threads that these messages are usually connected with ncurses, and I tried to follow the suggestions in those threads. But I have seen that libncurses5-dev is already installed (I re-installed it, too), I checked and reinstalled build essentials, I ran 'sudo apt-get update', too. Still the same messages, and when I enter in the directory of the program I see that make worked in part (part of the .o files are there)

Do you have some suggestions? If my gergon sounds strange, I apologize: English is only a second language for me, and this is the first time I use Ubuntu --> consider this last thing in your suggestions!
