将 SDL 库与自定义库结合使用会在使用第二个库时中断

问题描述 投票：0回答：2

我能够成功地将 SDL 库包含到我的 C 程序中，并能够使用以下代码打开一个窗口：

#include <stdio.h>
#include <SDL.h>
#include <MCSControl.h>


int initialize_window(void){
    if (0 != SDL_Init((SDL_INIT_EVERYTHING))){
        fprintf(stderr, "Error initializing SDL.\n");
        return 0;
    }
}

int main(int argc, char *argv[]) {
    initialize_window();
    SDL_Window* win = SDL_CreateWindow("GAME",
                                       SDL_WINDOWPOS_CENTERED,
                                       SDL_WINDOWPOS_CENTERED,
                                       1000, 1000, 0);
    float i=0;
    while (i<900000){
        i++;
    }



    return 0;

}

我用于该项目的 cmake 文件如下所示：

cmake_minimum_required(VERSION 3.27)
project(FullBuild.12.2.24.1 C)

set(CMAKE_C_STANDARD 11)

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "C:/Users/sbraun/CLionProjects/SDLAttempt1/cmake-build-debug")

add_executable(FullBuild.12.2.24.1 main.c)



find_package(SDL2 REQUIRED)
include_directories(${SDL2_INCLUDE_DIRS})
target_link_libraries(FullBuild.12.2.24.1 ${SDL2_LIBRARIES})

include_directories("C:/SDK/include")
target_link_libraries(FullBuild.12.2.24.1 "C:/SDK/lib/MCSControl.lib")

虽然不太好，但确实有效。 至少我认为是因为当我添加这些代码行时：

    SA_INDEX mcsHandle;
    const char locMCS1[] = "network:192.168.1.210:5000";
    SA_OpenSystem(&mcsHandle,locMCS1,"sync");
    SA_CloseSystem(mcsHandle);

正在使用 

MCSControl.h
库，整个事情突然不再起作用了。

是我得到的错误代码，但问题是我知道代码和函数是正确的，因为它们无需 SDL 库即可工作。

换句话说：SDL 库可以工作，MCSControl 库也可以工作，但是如果我使用这两个库编写一个程序，它就会崩溃。我需要任何帮助。

我尝试将 

target_link_libraries(FullBuild.12.2.24.1 "C:/SDK/lib/MCSControl.lib")
更改为 
target_link_libraries(FullBuild.12.2.24.1 "C:/SDK/lib64/MCSControl.lib)
并且成功了！ lib64 是包中提供的另一个 lib 文件夹。 不知道为什么它有效。也许另一个是为 32 个系统或 smthng 制作的
