without board level config.mk How to add CPPFLAGS

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)?

Dear zzs,

What exactly would you need board specific CPPFLAGS settings for?

If a train station is a place where a train stops,
                                           then what's a workstation?

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?

Dear zzs,

This will not be accepted.

U-Boot is supposed to be self-contained. It must not reference any source (or header) files outside the U-Boot directory.

You can probably write the file such that both U-Boot and Linux can use the same version.

This will not be accepted.

Make sure that U-Boot has all files it needs in it's own source tree.

C++ was an interesting and valuable experiment, but we've learned its
lessons and it's time to move on.

Does this means that there are no way to append custom cpp flags to CPPFLAGS ?

Dear zzs,

No, it means that your approach to include out-of-tree files has been rejected. Nothing more and not less.

And then how to do that thing : Append custom cpp flags to CPPFLAGS ?

e.g. -Wcomments

And after append them to CPPFLAGS, Does these flags appear in CFLAGS auto automatically ?

Dear zzs,

Use CFLAGS_$(BCURDIR) if you want to set this for all files in a specific directory, or CFLAGS_$(BCURDIR)/$(@F) if you want to set this for a single file only.
