EclipseCDT+；GNU臂

在修改了一些项目设置（即更改FPU类型）后，includes中出现了一些奇怪的条目，例如：

项目/未定义

在任何可以指定包含的常用位置（C/C++构建->设置->工具设置->编译器xy->包含）都不会显示这些内容

这显然是无效的包含路径在“问题”选项卡上创建了一条恼人的警告消息

有时修改FPU设置会使这些条目消失，或导致更多类似条目出现，但我在这里看不到任何逻辑行为。这是错误吗

确定找到它：workspace/.metadata/.plugins/org.eclipse.cdt.core/{NAME\u OF_PROJECT}.language.settings.xml

但我更喜欢删除它，而不是触摸。下次我打开eclipse并构建所有文件时，一切正常

这个文件存储在哪里，我找不到它it@taquionbcn试试这个：workspace.metadata.pluginsorg.eclipse.cdt.core/${projectname}.language.settings.xmlsome在这里-删除是有效的。我想知道这些条目是如何生成的。
