Hi Masahiro,
Yes I should remove this otherwise it will at best bloat the code for SPL. I think it is probably best just to revert that part of the Makefile.
Although actually I'm not sure how to have different flags for everything except SPL and examples/ - any clues?
Me neither.
But one possible solution is:
Add the CONFIG_SPL_BUILD conditional to config.mk to disable it for SPL.
ifeq ($(CONFIG_SPL_BUILD),) ifdef FTRACE CFLAGS += -finstrument-functions -DFTRACE endif endif
exmpales/ seems having troubles with FTRACE. So, disable it when FTRACE=1 is defined.
examples/Makefile is like this:
ifndef FTRACE ifndef CONFIG_SANDBOX subdir-y += standalone subdir-$(CONFIG_API) += api endif endif
BTW, can FTRACE build for all boards?
I checked out v2014.01 (pre-kbuild)
- make sandbox_config; make FTRACE=1 - make snow_config; make CROSS_COMPILE=arm-linux-gnueabi- FRACE=1
succeeded. But,
- make omap3_beagle_config; make CROSS_COMPILE=arm-linux-gnueabi- FRACE=1
faied with lots of undefined reference errors to __cyg_profile_func_enter/_exit.
I don't know why.
