Hi Guillaume,

in cross-armv7hl-gcc6 package, we get all the cross build tools, but
with the gcc version appended. So, we have
armv7hl-suse-linux-gnueabi-gcc-6 instead of
armv7hl-suse-linux-gnueabi-gcc.
This is a problem to build things such as u-boot or Linux kernel which
just use a CROSS_COMPILE prefix for the GCC tools in their Makefiles.
Is there any update-alternatives mechanism or something?
The solution is to specify CROSS_COMPILE= for binutils and CC= for gcc.
It will not work. Here is an extract of the U-Boot Makefile:
AS = $(CROSS_COMPILE)as
# Always use GNU ld
ifneq ($(shell $(CROSS_COMPILE)ld.bfd -v 2> /dev/null),)
LD = $(CROSS_COMPILE)ld.bfd
else
LD = $(CROSS_COMPILE)ld
endif
CC = $(CROSS_COMPILE)gcc
CPP = $(CC) -E
AR = $(CROSS_COMPILE)ar
NM = $(CROSS_COMPILE)nm
LDR = $(CROSS_COMPILE)ldr
STRIP = $(CROSS_COMPILE)strip
OBJCOPY = $(CROSS_COMPILE)objcopy
OBJDUMP = $(CROSS_COMPILE)objdump
You can note that a number of tools are missing from the openSUSE package.
I don't understand your point. I have successfully used
cross-aarch64-gcc{6,7} with mainline U-Boot!
As I said, you need both variables:
make CROSS_COMPILE=aarch64-suse-linux- CC=aarch64-suse-linux-gcc-7 ...
I tried:
make CROSS_COMPILE=armv7hl-suse-linux-gnueabi-
CC=armv7hl-suse-linux-gnueabi-gcc-6
and
make CROSS_COMPILE=arm-suse-linux-gnueabi- CC=arm-suse-linux-gnueabi-gcc-6
but both fail at AR tool call.
