在稍微修改一下 Tor 后，我在编译 Tor 时遇到了问题。
在名为 的文件control.c中，我添加了引用名为rend_service_t（位于 中rendservice.h）的结构的代码。我包括rendservice.h在顶部control.c，因为它以前不包括它。
如果我尝试使用包含的 Makefile，我会收到此错误：
control.c:2841: error: 'rend_service_t' undeclared (first use in this function)
我猜它rendservice.c没有被包含或没有首先编译，所以我检查了目录并且没有用于rendservice的目标文件。我对此有点困惑，因为它显然被包括在内。是什么导致这种情况发生？
我也尝试编辑Makefile.am/.inso that rendservice.c/hcome before control.c/h，但没有任何区别。
在control.c：
...
#include "rendservice.h"
...
static int
handle_control_addservice(control_connection_t *conn, uint32_t len,
const char *body)
{
smartlist_t *args;
rend_service_t *service;
...
在rendservice.c：
...
