[U-Boot] U-Boot: could not cross-compile u-boot tools

[Heiko Schocher]

Hello all,

just noticed, that it is not longer possible to cross-compile the
u-boot tools:

"Older" U-Boot (= before kbuild changes), could cross-compile the
u-boot tools:

$ git log

Is this a Bug, which should be fixed? Any hints?

Yes, this seems a way to go...

@Masahiro: What is your opinion?

Hmm, I don't like such a patch because
 [1] It changes too much
 [2] We must build tools in two steps.
    First time, build tools for host
          make O=path/to/buildhost/ silentoldconfig prepare scripts
    Second time, built tools for the target 
     make HOSTCC=$CROSS_COMPILE \
           KBUILD_SCRIPTROOT=path/to/buildhost/
            silentoldconfig prepare scripts
   It seems ridiculous to type so many magic commands.



Heiko, can you check if the following works for you?


Modify tools/Makefile as follows

  --- a/tools/Makefile
  +++ b/tools/Makefile
  @@ -5,6 +5,10 @@
   # SPDX-License-Identifier:     GPL-2.0+
   #
    
   +ifneq ($(CROSS_BUILD_TOOLS),)
   +HOSTCC = $(CC)
   +endif
   +
    #
    # toolchains targeting win32 generate .exe files
    #


Usage:
Build tools for host
     make  CROSS_COMPILE=<your_gcc_prefix> tools
Build tools for target
     make CROSS_BUILD_TOOLS=1  CROSS_COMPILE=<your_gcc_prefix> tools

Uknown Issue:
Tools are not stripped.
Too big for your target board?

Ok, if there is an easier way, that would be great!

But it should be possible to compile the "tools" for the
target. If this a serperate build step, that is as it was
before the kbuild changes, so that should be no problem.

I'm not really hapy with the additional CROSS_BUILD_TOOLS paramert -
but this may be a matter of taste, so the following is just a thought
and a question:

Would it make more sense to provide a sparate make target instead?

Say, something like this:

	Build tools for host
		make  CROSS_COMPILE=<your_gcc_prefix tools
	Build tools for target
		make  CROSS_COMPILE=<your_gcc_prefix cross_tools
	
?

Best regards,

Wolfgang Denk

I agree, this seems more natural.
