I want to build and install the Linux filesystem driver OperaFS. After compiling the source codes, "insmod" shows the error message "module invalid format", although I did download the package "linux-source", so I expect that the source is the source of my currently used kernel.
I did following so far:
$ uname -a
Linux debianstretch 4.9.0-3-686-pae #1 SMP Debian 4.9.30-2+deb9u2 (2017-06-26) i686 GNU/Linux
$ sudo su
$ aptitude update
$ aptitude upgrade (so I have the latest kernel now)
$ aptitude install linux-source libssl-dev
$ cd /usr/src
$ tar xf linux-source-4.9.tar.xz
$ cd linux-source-4.9
$ make oldconfig && make prepare
$ make scripts
Download ZIP from github.com/gameblabla/operafs ... and unzip ...
$ cd ~/Downloads/operafs
$ sudo su
$ make -C /usr/src/linux-source-4.9/ M=$PWD modules
$ make -C /usr/src/linux-source-4.9/ M=$PWD modules_install
$ modinfo operafs.ko
filename: ...
license: GPLv2
author: Serge van den Boom

depends:
vermagic: 4.9.30 SMP mod_unload modversions 686
$ insmod operafs.ko
insmod: ERROR: could not insert module operafs.ko: Invalid module format
$ modprobe operafs
modprobe: FATAL: Module operafs not found in directory /lib/modules/4.9.0-3-686-pae
What am I doing wrong?
