我检查了关于x64和x86冲突的不同问题，但这些问题都不适用于我的情况：我正在catkin_ws中创建一个名为beginner_tutorials的包。在我的包中，我介绍了src文件夹中的几个文件。然后，当执行catkin_make时，我得到以下内容：

我看不出在哪里可以设置任何关于x86的内容
由于某些原因，catkin_make为Visual Studio的X86(32位(体系结构生成了构建文件(注意/machine:X86选项和调用...binHostx86x86link.exe(，这就是为什么您会与X64(64位(ROS库发生链接冲突的原因。
我不能告诉你为什么，但我可以给你一些想法，看看哪里，也许可以为自己找到解决方案。
- 是否安装了Visual Studio和MSVC的X64版本
- 您是否遵循了ROS Windows安装指南中推荐的程序
- 您可以尝试强制使用
catkin_make --cmake-args -A X64构建X64，这有帮助吗？如果没有，是否会收到另一条错误消息，指向丢失的编译器或链接器
在你的bug搜寻中看起来不错。
