1. get linux kernel source

wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.3.9.tar.xz

2. install dependency packages

brew install openssl

3. compile and fix compile errors


choose using llvm toolchain to build.

# install llvm if you don't have it
brew install llvm

make ARCH=arm64 LLVM=1 menuconfig

GNU Make >= 3.82 is required

install make, and use gmake to compile

brew install make
# generate .config
gmake ARCH=arm64 LLVM=1 menuconfig
# compile
gmake ARCH=arm64 LLVM=1 -j`nproc --all`

typedef redefinition with different types ‘struct uuid_t’ vs ‘__darwin_uuid_t’

modify scripts/mod/file2alias.c file:

/* backwards compatibility, don't use in new code */
typedef struct {
        __u8 b[16];
} uuid_le;

// 在uuid_t结构体定义之前通过宏定义为其换个壳
#ifdef __APPLE__
#define uuid_t compat_uuid_t

typedef struct {
        __u8 b[16];
} uuid_t;
