How to export header files to a kernel module from source code of a kernel or other means to get a structure object #100
Description
Hello. My module requires some structure to function, for example, the timer_list structure of the linux/timer.h . How can I import it in my project?
Detail information about subject
I have added linux source to KernelPatch/kernel/. I have changed the Makefile.
Before:
INCLUDE_DIRS := . include patch/include linux/include linux/arch/arm64/include linux/tools/arch/arm64/include
After:
INCLUDE_DIRS := . include patch/include linux-4.14.156/include linux-4.14.156/arch/arm64/include linux-4.14.156/tools/arch/arm64/include
I got this error message:
make
