我做错了什么？您能否发送一些有用的链接，让我的 makefile 工作更轻松、更好？

get_next_line.o: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
Makefile:27: recipe for target 'gnl' failed
make: *** [gnl] Error 1

SRC = gnl.c

伙计们!为什么我不能接受"t" - 变量的地址？

flygs->type == 'X' ? t = a_ib_u(u->us, 16) : (a_lowcasealph(&(t = a_ib_u(u->us, 16))));
\\a_ib_u returns *char, a_lowcasealph take **char argument 

错误:无法获取'char*'类型的右值的地址

如何将变量与if语句中相同类型的值列表进行比较并使其可读且干净？

例如,我有以下内容,但有很多值,我想让它更具可读性.

if ((lst->type == 'p' || lst->type == 'x' || lst->type == 'X' ||
    lst->type == 'o' || lst->type == 'O' || (lst->type == 'd' ||
    lst->type == 'i' || lst->type == 'D'))
