我一直从Android.mk文件中收到此错误：
/home/sansari/mytree2/tbt/app/app.c:23:19: fatal error: debug.h: No such file or directory
#include <debug.h>
我要做的是将源从另一个目录导入我的jni项目。所以我甚至没有任何关于构建app.c的声明;它是通过制定隐含规则来完成的。惠斯特很棒。我的问题似乎是不知道如何告诉make嘿看看./include目录中的debug.h。那将是/ home / sansari / mytree2 / tbt / include。我该怎么办？您还需要哪些其他信息来帮助我？
为了提供一个参考点，我需要添加我试图运行make：
/home/sansari/AndroidStudioProjects/ThirdNDK/app/src/main/jni
我确实发出了-p选项来制作;实际上我正在运行ndk-build命令，这是一个运行make的shell。似乎make在我的sources目录中处理.mk fiels。如果没有为其他make文件添加include，make是否可以隐式执行此操作？这是我创建源文件所做的工作;看起来make会自动在这些目录中找到.mk文件并运行它们：
FILE_LIST := $(wildcard /home/sansari/mytree2/tbt/*.c)
FILE_LIST += $(wildcard /home/sansari/mytree2/tbt/**/*.c)
FILE_LIST += $(wildcard /home/sansari/mytree2/tbt/**/**/*.c)
FILE_LIST += $(wildcard /home/sansari/mytree2/tbt/**/**/**/*.c)
FILE_LIST += $(wildcard /home/sansari/mytree2/tbt/**/**/**/**/*.c)
FILE_LIST += $(wildcard /home/sansari/mytree2/tbt/**/**/**/**/**/*.c)
LOCAL_MODULE := HelloJNI
LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%) HelloJNI.c
关于这个问题的最新消息;我发现VPATH语句可以正常工作，并且实际上找到了该文件。但是编译器可能看不到它。我仍在阅读和挖掘，但如果有人可以提供帮助，我一定会感激。
@ognian - 嘿谢谢。我尝试了你的建议，似乎没有解决我的问题。我打印了LOCAL_C_FLAGS的内容只是为了验证。这就是我所拥有的：

从我在网上看到的，在我看来，我可以指向正确的目录，但我不知道还有什么需要发生才能看到它。网上还有一些关于编译器没有看到所需文件的可能性的评论。我想我需要更多地了解在使用正确的路径加载变量后会发生什么。我查看了vpath和VPATH，但根据make manual，路径的目录部分被make删除。所以我尝试创建一个变量并将所有头文件的路径加载到其中。然后我将内容复制到GPATH变量中，根据手册，它不会删除目录路径。但我想我不知道还需要做什么。这是我的Androdi.mk

您需要提供标题查找选项：
LOCAL_CFLAGS + = -I {your-header-path-here}
