How to get the full path and directory of a Makefile itself?

Posted on In QA

How to get the full path and directory of a Makefile itself like finding Bash script’s own path?

This 2 lines in Makefile get the full path and dir of the Makefile itself:

mkfile_path := $(abspath $(lastword $(MAKEFILE_LIST)))
mkfile_dir := $(dir $(mkfile_path))

The piece of code gets you Makefile, finds its absolute path and the directory. It does not rely on your work directory at all.

  1. how to get the files list included by a Makefile?
    For example:
    TOP?=/vobs
    include $(TOP)/util/mak/compiler.mk
    and compiler.mk may also include other files.
    How to get the all included file list?

    thanks

    1. make files paths : /home/ovsa/krupa/Makefile2/tool
      /home/ovsa/krupa/Makefile2/runtime
      /home/ovsa/krupa/Makefile2/License
      iam running the make in :: make -C ./krupa/Makefile2/License all

      Giving below error:

      make: Entering directory ‘/home/ovsa/krupakar/Makefile2/License’
      mkdir -p /home/ovsa/../License/lib /home/ovsa/../License/bin /home/ovsa/../License/src/lib
      mkdir: cannot create directory ‘/home/ovsa/../License’: Permission denied
      mkdir: cannot create directory ‘/home/ovsa/../License’: Permission denied
      mkdir: cannot create directory ‘/home/ovsa/../License’: Permission denied
      make: *** [Makefile:100: create_dirs] Error 1
      make: Leaving directory ‘/home/ovsa/krupakar/Makefile2/License’

      It is not taking the exact path of the makefile, It is creating the directory in /home
