C 编译裂土器插件时的未定义引用

我下载了存储库

获取此链接：已在src目录中创建了一些文件： 它是feal8.c，feal8.h，syb-prop\u REPROP.c，syb-prop\u REPROP.h和SybasePROP\u fmt\u plug.c 我在编译时收到一个错误：

有人能帮我吗？

您缺少一个对象文件？此外，您可能需要查看

fmt\u SybasePROP

的定义。我认为include或path

[root@vakxden-笔记本电脑（src）#grep-r fmt_SybasePROP/SybasePROP_fmt_plug.c:extern struct fmt_main fmt_SybasePROP/SybasePROP_fmt_plug.c:struct fmt_main fmt_SybasePROP={./fmt_externs.h:extern struct fmt_main fmt_SybasePROP；/fmt_registers.h:john_register_one（&fmt_SybasePROP）；

文件SybasePROP fmt_plug.c在

SetKey

和

Encrypt

中是什么？它们是您自己的函数？名称类似于

SetKey（3）

和

加密（3）

（注意：大多数命名约定在c函数中不使用大写字母）。例如SetKey:

[root@vakxden-笔记本电脑src]#grep-r SetKey../feal8.h:void SetKey（ByteType*）；/feal8.c:void SetKey（ByteType*KP）。/syb-prop_repo.c:SetKey（（ByteType*）key）

在其他文件中未提及：-feal8.c-feal8.h syb-prop_repo.c
