Hi guys:
I am a beginner of U-Boot, and now I am trying to understand the Makefiles.
There are some variables in the Makefile under the top directory, which are used without being defined and initiated. For example: PLATFORM_LIBS: "PLATFORM_LIBS += --no-warn-mismatch -L $(shell dirname `$(CC) $(CFLAGS) -print-libgcc-file-name`) -lgcc", and OBJCFLAGS: "$(OBJCOPY) ${OBJCFLAGS} -O srec $< $@". I've checked all the *.mk which are included directly or indirectly by this Makefile and have not find any defination or initiation. I also have made sure that they are not environment variables of LINUX.
I'm so wondering. If anyone could give me an explaination, I will appreciate it so much!
Best Wishes
