From 6fc9aacad49e3fbecd270c266850d50c453d52ef Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Sun, 4 Aug 2024 14:50:57 +0900 Subject: Makefile: add $(srctree) to dependency of compile_commands.json target When trying to build compile_commands.json for an external module against the kernel built in a separate output directory, the following error is displayed: make[1]: *** No rule to make target 'scripts/clang-tools/gen_compile_commands.py', needed by 'compile_commands.json'. Stop. This is because gen_compile_commands.py was previously looked up using a relative path to $(srctree), but commit b1992c3772e6 ("kbuild: use $(src) instead of $(srctree)/$(src) for source directory") stopped defining VPATH for external module builds. Prefixing gen_compile_commands.py with $(srctree) fixes the problem.
