Because the board level config.mk not suggested now(I had seen in some email message). So now how can I add my own CPPFLAGS or PLATFORM_CPPFLAGS direct in board level Makefile (For some header search path)?
What exactly would you need board specific CPPFLAGS settings for?
I just want to add a -iquote flag for searching my header file which in the linux driver dir.
I had wrote a linux driver and has a header file in it. Now I want to write this driver for u-boot. So I think copy that header file to u-boot source tree is not a good idea because I must modify two same file when something wrong.
So I want add "-iquote my/header/dir" to CPPFLAGS
The Makefile like this :
ifeq "$(REPOS_COMMON_DIR)" "" $(error "common repository path must defined in env!") else CPPFLAGS += -iquote $(REPOS_COMMON_DIR)/include -iquote $(REPOS_LINUX_DRIVER_DIR) endif
...
COBJS-$(CONFIG_ALTERA_FPGA) += cfg-altera-fpga.o
But when make it, the arm-linux-gcc command line not have my "-iquote" flags.
Now I add them to both CPPFLAGS and CFLAGS, like this:
ifeq "$(REPOS_COMMON_DIR)" "" $(error "common repository path must defined in env!") else CPPFLAGS += -iquote $(REPOS_COMMON_DIR)/include -iquote $(REPOS_LINUX_DRIVER_DIR) CFLAGS += -iquote $(REPOS_COMMON_DIR)/include -iquote $(REPOS_LINUX_DRIVER_DIR) endif
...
COBJS-$(CONFIG_ALTERA_FPGA) += cfg-altera-fpga.o
It now works! but it's so strange!!
Is there any good methods?
