FAT_FS build problems

Question

I just cloned the latest zephyr from github and tried building fat_fs. Got this error:

/Users/macbook/zephyrproject/zephyr/zephyr/samples/subsys/fs/fat_fs/src/main.c:11:10: fatal error: storage/disk_access.h: No such file or directory

   11 | #include <storage/disk_access.h>

Although the file is present in:

/Users/macbook/zephyrproject/zephyr/zephyr/include/storage/disk_access.h

Also in: /Users/macbook/zephyrproject/zephyr/zephyr/include/disk/disk_access.h.

Hard-coding the full path takes care of it:

#include "/Users/macbook/zephyrproject/zephyr/zephyr/include/storage/disk_access.h"

Next problem:

In file included from /Users/macbook/zephyrproject/zephyr/zephyr/samples/subsys/fs/fat_fs/src/main.c:11:

/Users/macbook/zephyrproject/zephyr/zephyr/include/storage/disk_access.h:23:10: fatal error: drivers/disk.h: No such file or directory

   23 | #include <drivers/disk.h>

Again, hard-coding helps:

#include </Users/macbook/zephyrproject/zephyr/zephyr/include/drivers/disk.h>

Probably something wrong with my paths, etc. Any help would be appreciated.

However, next problem is:

/Users/macbook/zephyrproject/zephyr/subsys/disk/disk_access.c:18:1: warning: data definition has no type or storage class
   18 | LOG_MODULE_REGISTER(disk);
      | ^~~~~~~~~~~~~~~~~~~

/Users/macbook/zephyrproject/zephyr/subsys/disk/disk_access.c:18:1: warning: parameter names (without types) in function declaration

  129 |   LOG_ERR("invalid disk interface!!");
      |   ^~~~~~~
/Users/macbook/zephyrproject/zephyr/subsys/disk/disk_access.c:142:2: warning: implicit declaration of function 'LOG_DBG' [-Wimplicit-function-declaration]
  142 |  LOG_DBG("disk interface(%s) registred", disk->name);
      |  ^~~~~~~

And here I'm lost. How do I fix this?

And if there are other problems after this, could you point me in the right direction?
