Hi, I'm building u-boot (am335x_evm config) using arm-none-eabi toolchain under Cygwin. When trying to build unmodified v2014.04 tag I get some errors. However, if I remove the "-ansi" flag from the Makefile, everything builds fine:
-ifeq ($(HOSTOS),cygwin) -HOSTCFLAGS += -ansi -endif I tried tracking down where those lines came from and why building under Cygwin requires separate treatment. I found our this originates from the following commit (dated Jan 2008): SHA-1: 883e3925d99a8dd69c5b0201cba5b1887f88f95c * Fix build problems under Cygwin This patch allows u-boot to build without error in a cygwin environment. Cygwin does not define __u64 in it's include/asm/types.h file. The -idirafter flag in the u-boot build causes the inclusion of the cygwin types.h file as opposed to u-bot/include/asm/types.h file which does define __u64. Subsequently, sha1.c compile fails due to unknown symbol. Signed-off-by: Brian Miller <raptorbr...@netscape.net> This comment does not really explain why "-ansi" flag is required. Personally, I don't see any reason for it. Maybe it should be removed at all?
