如何编译使用term.h的程序？

我尝试编译以下代码：

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <term.h>

//#include "/usr/include/term.h"

void clear_screen(void) {
    if (!cur_term) {
        int result;
        setupterm( NULL, STDOUT_FILENO, &result );
    if (result <= 0)
        return;
    }

    putp( tigetstr( "clear" ) );
}

int main(void) {
    puts("I am going to clear the screen");
    sleep(1);
    clear_screen();
    puts("Screen Cleared");
    sleep(1);
    clear_screen();

    return 0;

}

该程序测试使用term.h头文件清除终端屏幕的功能。我已经安装了所有需要的库：libncurses5并且libncurses5-dev当我使用或不使用-lncurses,-lcurses和-lterminfo参数gcc编译程序时，我得到了上面的输出：

In file included from clear_screen_UNIX.c:5:0:
clear_screen_UNIX.c:9:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘->’ token
 void clear_screen(void) {
      ^
clear_screen_UNIX.c: In function ‘main’:
clear_screen_UNIX.c:23:14: error: called object is not a function or function pointer
  clear_screen();
              ^
clear_screen_UNIX.c:26:14: error: called object is not a function or function pointer
  clear_screen();
              ^

term.h此外，当我使用其完整路径明确包含标头时，我将其/usr/include/term.h作为输出：

In file included from clear_screen_UNIX.c:7:0:
/usr/include/term.h:125:21: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘->’ token
 #define CUR cur_term->type.
                     ^
/usr/include/term.h:202:40: note: in expansion of macro ‘CUR’
 #define clear_screen                   CUR Strings[5]
                                        ^
clear_screen_UNIX.c:9:6: note: in expansion of macro ‘clear_screen’
 void clear_screen(void) {
      ^
clear_screen_UNIX.c: In function ‘main’:
clear_screen_UNIX.c:23:14: error: called object is not a function or function pointer
  clear_screen();
              ^
clear_screen_UNIX.c:26:14: error: called object is not a function or function pointer
  clear_screen();
              ^

根据上面的说法，term.hheader里面有一些错误，我不相信。

那么我是否需要安装更多的包或配置一些设置才能使代码成功编译？
