The goal is to only execute recipes when there is an actual change in the prerequisites. There are several issues which cause the nuttx binary target to be re-made every time the top level make is run. 1. Previously the target nuttx$(EXEEXT), was used, but make resolved this in the relative directory make -C $(ARCH_SRC), and couldn’t find it (need an absolute path: `$(TOPDIR)/..). 2. The .tmp prerequisite for nuttx was always deleted 3. libboard's recipe had a sub-make which may or may not update that target. This was a phony target, and was therefore always considered out of date. These issues were causing the nuttx recipe to be run every make, which was hiding some missing prerequisites: 1. the .config is a prerequisite for the .tmp target 2. libapps.a (and other linklibs) are pre-requisites for nuttx Changes: The changes are only in the build system, and only for arm. Track nuttx$(EXEEXT) via vpath so Make knows when it's already up to date without an explicit path. Add $(TOPDIR)/.config as a dependency to the linker script preprocessing so config changes trigger re-preprocessing. Keep the .tmp linker script on disk (clean already removes it) so timestamp-based dependency checking works across builds. These .tmp files need to be added to the gitignore or the CI will complain. Use FORCE pattern for board/libboard to ensure it's always checked but use the actual library file as the link dependency so nuttx is only re-linked when library content changes. Add staging libs as dependency to nuttx link rule so changed app libs trigger re-link. Signed-off-by: Liam Hickey <williamhickey@geotab.com> |
