ncurses & curses - compiler undefined references

Okay so I had originally been attempting to use some headers that were supposedly for windows only, my bad, but I've gone and just reproduced what I need using curses.h. However I am still receiving the exact same kind of error. ``` "/usr/bin/gmake" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf gmake[1]: Entering directory `/home/josh/Projects/Testing grounds/kbhit' "/usr/bin/gmake" -f nbproject/Makefile-Debug.mk dist/Debug/GNU-Linux-x86/kbhit gmake[2]: Entering directory `/home/josh/Projects/Testing grounds/kbhit' mkdir -p build/Debug/GNU-Linux-x86 rm -f build/Debug/GNU-Linux-x86/main.o.d g++ -c -g -MMD -MP -MF build/Debug/GNU-Linux-x86/main.o.d -o build/Debug/GNU-Linux-x86/main.o main.cpp mkdir -p dist/Debug/GNU-Linux-x86 g++ -o dist/Debug/GNU-Linux-x86/kbhit build/Debug/GNU-Linux-x86/main.o build/Debug/GNU-Linux-x86/main.o: In function `kbhit()': /home/josh/Projects/Testing grounds/kbhit/main.cpp:20: undefined reference to `stdscr' /home/josh/Projects/Testing grounds/kbhit/main.cpp:20: undefined reference to `wgetch' /home/josh/Projects/Testing grounds/kbhit/main.cpp:23: undefined reference to `ungetch' collect2: ld returned 1 exit status gmake[2]: *** [dist/Debug/GNU-Linux-x86/kbhit] Error 1 gmake[2]: Leaving directory `/home/josh/Projects/Testing grounds/kbhit' gmake[1]: *** [.build-conf] Error 2 gmake[1]: Leaving directory `/home/josh/Projects/Testing grounds/kbhit' gmake: *** [.build-impl] Error 2 ``` So, I am not 100% sure that the code should even work as I expect it to. I am just trying to compile this to test it. According to the curses.h documentation getch is supposed to return the value ERR if no keys are queued. I don't really know what else is required here, I thought all I needed to do was include the header the definitions were in. It seems like that isn't enough though, there must be something I have missed. Here is the short test I am trying to compile ``` #include <cstdlib> #include <iostream> #include <curses.h> #include <ncurses.h> using namespace std; bool kbhit() { int ch = getch(); if(ch != ERR) { ungetch(ch); return true; } return false; } int main() { while(!kbhit()) { cout << "no input"; } cout << "Mummy, it's over."; return 0; } ```
