This makefile supports + building NuttX archives, as well as supervising the building of all + of the defined PX4 firmware configurations. + + Try 'make help' in the parent directory for documentation. + +firmware.mk + + Manages the build for one specific firmware configuration. + See the comments at the top of this file for detailed documentation. + + Builds modules, builtin command lists and the ROMFS (if configured). + + This is the makefile directly used by external build systems; it can + be configured to compile modules both inside and outside the PX4 + source tree. When used in this mode, at least BOARD, MODULES and + CONFIG_FILE must be set. + +module.mk + + Called by firmware.mk to build individual modules. + See the comments at the top of this file for detailed documentation. + + Not normally used other than by firmware.mk. + +nuttx.mk + + Called by ../Makefile to build or download the NuttX archives. + +upload.mk + + Called by ../Makefile to upload files to a target board. Can be used + by external build systems as well. + +setup.mk + + Provides common path and tool definitions. Implements host system-specific + compatibility hacks. + +board_<boardname>.mk + + Board-specific configuration for <boardname>. Typically sets CONFIG_ARCH + and then includes the toolchain definition for the board. + +config_<boardname>_<configname>.mk + + Parameters for a specific configuration on a specific board. + The board name is derived from the filename. Sets MODULES to select + source modules to be included in the configuration, may also set + ROMFS_ROOT to build a ROMFS and BUILTIN_COMMANDS to include non-module + commands (e.g. from NuttX) + +toolchain_<toolchainname>.mk + + Provides macros used to compile and link source files. + Accepts EXTRADEFINES to add additional pre-processor symbol definitions, + EXTRACFLAGS, EXTRACXXFLAGS, EXTRAAFLAGS and EXTRALDFLAGS to pass + additional flags to the C compiler, C++ compiler, assembler and linker + respectively. + + Defines the COMPILE, COMPILEXX, ASSEMBLE, PRELINK, ARCHIVE and LINK + macros that are used elsewhere in the build system. diff --git a/makefiles/firmware.mk b/makefiles/firmware.mk index b63aa28d7..e6a45a4e8 100644 --- a/makefiles/firmware.mk +++ b/makefiles/firmware.mk @@ -223,12 +223,15 @@ MODULE_OBJS := $(foreach path,$(dir $(MODULE_MKFILES)),$(WORK_DIR)$(path)module .PHONY: $(MODULE_OBJS) $(MODULE_OBJS): relpath = $(patsubst $(WORK_DIR)%,%,$@) $(MODULE_OBJS): mkfile = $(patsubst %module.pre.o,%module.mk,$(relpath)) +$(MODULE_OBJS): workdir = $(@D) $(MODULE_OBJS): $(GLOBAL_DEPS) $(NUTTX_CONFIG_HEADER) + $(Q) $(MKDIR) -p $(workdir) $(Q) $(MAKE) -r -f $(PX4_MK_DIR)module.mk \ - MODULE_WORK_DIR=$(dir $@) \ + -C $(workdir) \ + MODULE_WORK_DIR=$(workdir) \ MODULE_OBJ=$@ \ MODULE_MK=$(mkfile) \ - MODULE_NAME=$(lastword $(subst /, ,$(@D))) \ + MODULE_NAME=$(lastword $(subst /, ,$(workdir))) \ module # make a list of phony clean targets for modules diff --git a/makefiles/module.mk b/makefiles/module.mk index 0fe6f0ffe..db6f4e15e 100644 --- a/makefiles/module.mk +++ b/makefiles/module.mk @@ -39,6 +39,10 @@ # symbols, as the global namespace is shared between all modules.
