"Exec format error" on openSUSE Tumbleweed

[dradtke]

Following the instructions in the README and ensuring that I had the kernel-default-devel package installed with the correct version, I was able to build the modules successfully:

Build output:

but modprobe then runs into the following error:

modprobe: ERROR: could not insert 'ashmem_linux': Exec format error
modprobe: ERROR: could not insert 'binder_linux': Exec format error

Kernel version: 4.20.13-1-default DKMS version: 2.6.1-1.2

Any ideas what could be going wrong?

Latest tumbleweed with kernel 5 works well, maybe I would check later on 4.20.13

Does you compiled with the right CC? Exec format error means that you are trying to use an elf compiled for a different and incompatible instruction set than your machine's architecture supports
