Hi All,
I have an SDK populated from an image.
After sourcing the SDK env file, I try to run make on a project with this command :
>
> make CC="$CC" LD="$LD" CFLAGS="${CFLAGS}
> --sysroot=/media/talel/data/sdk-multigate/sysroots/aarch64-poky-linux"
> CXXFLAGS="${CXXFLAGS}
> --sysroot=/media/talel/data/sdk-multigate/sysroots/aarch64-poky-linux"
I specified the CFLAGS and CXXFLAGS as mentionned in Yocto document (part 5.2 Makefile-Based projects) : https://www.yoctoproject.org/docs/1.1.2/adt-manual/adt-manual.html
Now I have this error:

I see that your linker is not using proper sysroot perhaps using
LD=${CC} might help.

Hi,
Thanks for the reply.
Setting LD to $CC didn't work as well.

Pass LDFLAGS as CLFAGS as well, you need to use --syroot option during
link as well

Hi,
Actually the Yocto SDK sets LD variable correctly : here is its value :
aarch64-poky-linux-ld --sysroot=/media/talel/data/sdk-multigate/sysroots/aarch64-poky-linux
Now I'm stuck with linking,
Please help me.
Thansk, Talel
