Compiling a driver for MIPS architecture on 4.4 kernel

Question

I am compiling a driver for MIPS architecture on 4.4 kernel. It seems compiler is not including

/linux-4.4.34/include/linux/types.h 

but instead it includes

/linux-4.4.34/include/uapi/linux/types.h 

Because of this I see below error.I did not include the path /linux-4.4.34/include/uapi in driver makefile.Could someone explain how can driver include the path /include/linux and not /include/uapi/linux ?

./arch/mips/include/asm/mipsregs.h:871:33: error: unknown type name 'u16'

Answer 1

In mipsisa32-be-elf.inc file, given the path /kernel/include/uapi in -isystem compilation flag. This helps to solve the above compilation issue.
