Ich muss zugeben ich bin bei der ganzen Makefile-Sache noch ein blutiger Anfänger. Ich habe ein Beispiel zu Xenomai's Posix Skin und ein dazugehöriges Makefile. Das Makefile sieht folgendermassen aus:
Code: Alles auswählen
###### CONFIGURATION ######
### List of applications to be build
APPLICATIONS = satch
### Note: to override the search path for the xeno-config script, use "make XENO=..."
### List of modules to be build
MODULES = satch
### Note: to override the kernel source path, use "make KSRC=..."
all::
satch: satch.c
###### USER SPACE BUILD (no change required normally) ######
ifeq ($(KERNELRELEASE),)
ifneq ($(APPLICATIONS),)
### Default Xenomai installation path
XENO ?= /usr/xenomai
XENOCONFIG=$(shell PATH=$(XENO):$(XENO)/bin:$(PATH) which xeno-config 2>/dev/null)
### Sanity check
ifeq ($(XENOCONFIG),)
all::
@echo ">>> Invoke make like this: \"make XENO=/path/to/xeno-config\" <<<"
@echo
endif
CC=$(shell $(XENOCONFIG) --cc)
CFLAGS=-DCONSUMER $(shell $(XENOCONFIG) --posix-cflags) $(APP_CFLAGS)
LDFLAGS=$(shell $(XENOCONFIG) --posix-ldflags) $(APP_LDFLAGS)
# This includes the library path of given Xenomai into the binary to make live
# easier for beginners if Xenomai's libs are not in any default search path.
LDFLAGS+=-Xlinker -rpath -Xlinker $(shell $(XENOCONFIG) --libdir)
all:: $(APPLICATIONS)
clean::
$(RM) $(APPLICATIONS) *.o
endif
endif
###### KERNEL MODULE BUILD (no change required normally) ######
ifneq ($(MODULES),)
### Default to sources of currently running kernel
KSRC ?= /lib/modules/$(shell uname -r)/build
OBJS := ${patsubst %, %.o, $(MODULES)}
CLEANMOD := ${patsubst %, .%*, $(MODULES)}
PWD := $(shell if [ "$$PWD" != "" ]; then echo $$PWD; else pwd; fi)
### Kernel 2.6
PATCHLEVEL:=$(shell sed 's/PATCHLEVEL = \(.*\)/\1/;t;d' $(KSRC)/Makefile)
ifeq ($(PATCHLEVEL),6)
obj-m := $(OBJS)
EXTRA_CFLAGS := -DPRODUCER -I$(KSRC)/include/xenomai -I$(KSRC)/include/xenomai/posix $(ADD_CFLAGS)
all::
$(MAKE) -C $(KSRC) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) SUBDIRS=$(PWD) modules
$(RM) *.o
### Kernel 2.4
else
ARCH ?= $(shell uname -i)
INCLUDE := -I$(KSRC)/include/xenomai -I$(KSRC)/include/xenomai/compat -I$(KSRC)/include/xenomai/posix
CFLAGS += $(shell $(MAKE) -s -C $(KSRC) CC=$(CC) ARCH=$(ARCH) SUBDIRS=$(PWD) modules) $(INCLUDE)
all:: $(OBJS)
endif
## Target for capturing 2.4 module CFLAGS
modules:
@echo "$(CFLAGS)"
clean::
$(RM) $(CLEANMOD) *.o *.ko *.mod.c Module*.symvers Module.markers modules.order
$(RM) -R .tmp*
$(RM) .runinfo
endif
