Buildroot not compiling

Question

every time I run make

it starts compiling but then stops and tells me this:

tmp-divrem_1.s:130: Error: selected processor does not support `mls r1,r4,r8,r11' in ARM mode
tmp-divrem_1.s:146: Error: selected processor does not support `mls r1,r4,r8,r11' in ARM mode

From the config it looks like you're compiling for i586, not arm or aarch64.

If you type make list-defconfigs, then it will show you a list; here's an excerpt:

raspberrypi2_defconfig              - Build for raspberrypi2
raspberrypi4_64_defconfig           - Build for raspberrypi4_64
raspberrypi4_defconfig              - Build for raspberrypi4
sheevaplug_defconfig                - Build for sheevaplug

Once you have identified the defconfig you need, then you can do this:

make raspberrypi4_defconfig

and it'll initialize a basic configuration for the selected target. With this configuration, your compilation should run to completion.
