我不熟悉使用第三方的东西,也不熟悉使用 C 在 Windows 上工作。
我目前正在尝试简单地使用并包含这个 third party library.
我已经下载它并将所有文件放在我的主文件旁边的 include/subhook/
中。
我的 main.c
看起来像 github 页面上的示例,除了它包含 include/subhook/subhook.h
:
#include <stdio.h>
#include "include/subhook/subhook.h"
subhook_t foo_hook;
void foo(int x) {
printf("real foo just got called with %d\n", x);
}
void my_foo(int x) {
subhook_remove(foo_hook);
printf("foo(%d) called\n", x);
foo(x);
subhook_install(foo_hook);
}
int main() {
foo_hook = subhook_new((void *)foo, (void *)my_foo, 0);
subhook_install(foo_hook);
foo(123);
subhook_remove(foo_hook);
subhook_free(foo_hook);
}
这是我的 CMakeLists.txt 文件。我也试过包含所有其他 .c 文件,但它不起作用:
cmake_minimum_required(VERSION 3.7)
project(NexusHookSubhook)
set(CMAKE_C_STANDARD 11)
include_directories(include/subhook)
set(SOURCE_FILES main.c include/subhook/subhook.h include/subhook/subhook.c)
add_executable(NexusHookSubhook ${SOURCE_FILES})
当我尝试编译时,我得到了一大堆这些错误(我假设,链接/包含库错误)。谁能解释我在这里做错了什么?

附加说明:我在 Windows 10 上使用 Cygwin 2.8.0 和 CMake 3.7.2(使用 make 和 gcc 包以及 GDB 7.11.1)
最佳答案
你完全错过了 CMakeFiles 中的链接部分
target_link_libraries(
NexusHookSubhook
${subhookLib}
m
)
其中subhookLib是subhook的库
