From e2bad142bb3de836c5fbb3dff704578f5a73d8e6 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 6 Mar 2024 19:42:22 +0900 Subject: kbuild: unexport abs_srctree and abs_objtree Commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any directory") exported abs_srctree and abs_objtree to avoid recomputation after the sub-make. However, this approach turned out to be fragile. Commit 5fa94ceb793e ("kbuild: set correct abs_srctree and abs_objtree for package builds") moved them above "ifneq ($(sub_make_done),1)", eliminating the need for exporting them. These are only needed in the top Makefile. If an absolute path is required in sub-directories, you can use $(abspath ) or $(realpath ) as needed.
