That doesn't make sense, does it?That's $prefix/$target/lib. Note that it's inside the sysroot too. So in your case the host directory searched would be /opt/cross/sysroot.arm-linux-gnueabihf/opt/cross/arm-linux-gnueabihf/lib
Which is why I said that I don't think that makes sense :-) I would understand it if no sysroot was set.
$prefix/$target was an idea that predated sysroot for a place to put target and tool specific info. You might see that directory referred to as tooldir.
Yeah, I see that binutils places hardlinks in bin and ldscripts in the lib directory. IMHO I think $prefix/$target should be what the sysroot would or could be set at, but if I do that now host and target stuff would be mixed. Which, right now, makes (only?) sense with a target that newlib supports.
But ok, for now on tooldir and sysroot needs to be two different directories if you want to use sysroot.
