编译错误：“stdint.h：没有那个文件或目录”

Question

when trying to build kernel

I got this error

/usr/lib/gcc/x86_64-linux-gnu/7/include/stdint.h:9:26: error: no include path in which to search for stdint.h
 # include_next <stdint.h>

when i looked in /usr/lib/gcc/x86_64-linux-gnu/7/

there is just one stdint.h and under include-fixed dir there are : limit.h and syslimit.h

Answer 1

At the end,

i resolved the problem by adding to KBUILD_CFLAGS += $(call cc-option,-ffreestanding)

That restricts gcc use standard stdint stdint-gcc.h
