如何使用额外的include路径（包括外部头文件，yaml，boost等库文件）构建树外linux模块

Question

I am trying to build an out-of-tree linux kernel that should take into account external headers files comming from pre- compiled and installed custom libraries. My linux module will use functions from a shared library via a C-interface. How is it possible to prevent kernel Makefile of the existence of such files?

    obj-m+= hello_module.o
    $(MAKE) -C $(KDIR) M=$(OUTDIR) modules
    #additional include path
    INCLUDES :=\ 
             -I $(PROJECT_ROOT)/deps1
             -I $(PROJECT_ROOT)/deps2
             -I $(PROJECT_ROOT)/deps3

So how can I include this in $(MAKE) line above? Thanks in advance, Rgds sahbi

You cannot link user space libraries into modules. But you can link multiple files with the following Makefile:

obj-m := combinedmodule.o
combinedmodule-objs := part1.o part2.o


all:
        make -C $(KERNEL_SRC) M=$(PWD) modules
