对“__mingw_vsscanf”的未定义引用
Posted
技术标签:
【中文标题】对“__mingw_vsscanf”的未定义引用【英文标题】：undefined reference to `__mingw_vsscanf' 【发布时间】：2021-11-24 09:44:10 【问题描述】：我目前正在收听 Udemy 的一些视频。这与使用 raylib 制作基本游戏有关。因此，在开始之前，课程会先制作一个弹出窗口，这是我在下面使用的代码。
#include "raylib.h"
int main()
InitWindow(300, 500, "test window");
我下载了课程为此使用的 vscode 模板。因此，从这一点开始，我将模板放在以下位置：
-
创建文件夹 GameDev
将 vscode 模板放入 GameDev 文件夹中
复制并粘贴模板，这样我所做的任何更改都不会改变原始模板。那是万一我搞砸了，然后我可以重新开始哈哈。在模板文件夹内部是这样设置的。
template-folder-contents
因此，对于我最初在上面发布的代码，我在#include "raylib.h" 下有一条红色波浪线。我花了一段时间才最终弄清楚如何更新配置设置中的包含路径。然后红色的波浪线消失了。那时我点击标签运行，然后开始调试。在终端中，它显示了这一点，并且不会走得更远。不会创建弹出窗口。
terminal-status//
有几行显示未定义的引用。这就是我不确定未定义引用是什么意思的地方。我点击了问题选项卡，它没有显示任何错误。在我看来，可能有一个未链接的库或标题导致上面的终端状态图片中看到的内容。这是我最好的猜测，如果我对此完全错误，也不会感到惊讶。我可以从这里学到的任何东西都很棒！如果它有帮助，谁愿意在这里看看这个是 launch.json 代码

【问题讨论】：
tasks.json 文件比launch.json 文件更有趣。请edit 您的问题改为显示tasks.json 文件。
好的，我添加了 tasks.json 代码@Someprogrammerdude
看看Makefile 也可能很有用。以及“清理”后构建输出的完整和完整的复制粘贴。查看make 运行的命令，尤其是选项和标志及其order 会很有趣。因为链接事物的顺序可能是个问题。如果 raylib 是使用不同版本的 MinGW 构建的，这也可能是一个问题。您是从二进制包安装 raylib，还是从源代码构建？
@Someprogrammerdude 我终于在工作中得到了休息，所以我添加了 makefile。然后复制粘贴输出。为了回答你的问题，我从二进制包中安装了 raylib。那是来自 raylib 网站。
@Someprogrammerdude 嘿，非常感谢您对我的问题的回答。我花了很多时间试图消化您所说的用于构建库的编译器版本与用于构建应用程序的版本之间可能存在不匹配的情况。这正是发生的事情！直到今天早上才发现我的 dum**** 在系统路径中的 raylib 中没有编译器。我为此感到非常愚蠢。然后它实际上并没有工作，直到我更新了 makefile 中的编译器路径......哈哈，现在我不会忘记这一点。再次感谢我学到的每一点都会有所帮助！
【参考方案1】：
我会尽量写出最佳答案，以便其他人可以使用。我正在使用 raylib 学习如何制作基本游戏。如果您正在使用 VS Code 并且看到输出消息说“未定义的引用”，没有看到任何红色波浪线错误，那么您应该首先尝试查看环境变量设置中的路径设置。这是在 Windows 中，我使用的是 Windows 10。如果您在环境变量中没有此设置，那么 VS Code 很可能不会选择它。然后在 VS Code 中确保在 makefile 和 c/c++ 配置设置中设置路径
