c - Ubuntu 上的 makefile 问题

Question

我正在尝试安装一个由包含一些 C 文件的文件夹组成的程序。我运行 makefile 但出现以下错误:

/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1128: undefined reference to `tgoto'
/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1129: undefined reference to `tputs'
/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1138: undefined reference to `tputs'
/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1145: undefined reference to `tputs'
/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1154: undefined reference to `tputs'
readline/libreadline.a(display.o): In function `delete_chars':
/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1182: undefined reference to `tgoto'
/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1183: undefined reference to `tputs'
/home/silviu/Desktop/tipsy-2.2.3d/code/readline/display.c:1189: undefined reference to `tputs'

/home/silviu/Desktop/tipsy-2.2.3d/code/readline/signals.c:301: undefined reference to `tputs'
collect2: error: ld returned 1 exit status

你知道我该如何解决吗？ (在 Ubuntu 上)

Answer 1

您已使用tputs在c程序中，所以你必须使用 #include <curses.h>和#include <term.h> 。 undefined reference 是链接器错误。在编译 c 程序时的 Makefile 中，您应该链接 -lcurses或-lncurses 。将类似的行添加到您的 Makefile 中。使用适当的链接库进行编译。

例如

gcc file.c -o output_file -lcurses -ltermcap

或

gcc file.c -o output_file -lcurses -ltermcap
