我试图在Mac OS X 10.6.8上编译基于ncurses的应用程序，但出现此错误.

I'm trying to compile ncurses based app on Mac OS X 10.6.8 but I get this error.

Undefined symbols for architecture x86_64:
  "_initscr", referenced from:
      _main in ccf8K8YG.o
  "_printw", referenced from:
      _main in ccf8K8YG.o

  "_endwin", referenced from:

可能是什么问题?

推荐答案

我很确定这是因为编译时没有包含 ncurses 库.

I'm pretty sure this is because you're not including the ncurses library when compiling.

尝试添加:

-lncurses

编译时.

例如(对于C ++):

For example (for C++):

g++ -o hello main.cpp -lncurses

或使用gcc(用于C):

Or using gcc (for C):

gcc -o hello main.cpp -lncurses

此简短命令将编译并执行:

This short command will compile and execute:

gcc -o hello main.cpp -lncurses && ./hello

这是我的问题，希望这对某人有帮助.
