dmesg "disagrees about version of symbol module_layout" modprobe fails with self compiled cdc_acm
Hello, I try to compile cdc_acm kernel driver to make out of NAS a zwave control center (USB Zwave stick). First I've tried to compile ftdi_sio und succeded, modprobe can load this driver. what've...
Starting with I believe ReadyNAS OS 6.5.0 I found that the only way to successfully compile kernel modules is to do it directly on the ReadyNAS. All other ways I tried (using VMs, cross compiling and dedicated hardware) simply failed because of the symbol mismatches you're experiencing.

hm, I hope NetGear tries to fix this, the VM is realy nice. In the mean time, I've failed to compile directly on NAS, the headers are missing. have had tried the obvious
apt-get install linux-headers-$(uname -r) or
apt-get install linux-headers or
apt-get install linux-headers-generic.... there are no such packeges available. Should I mess with apt sources to install headers? Or is there some other possibilities to compile kernel drivers?
Huh? You don't need the kernel headers. Everything you need is in the GPL archive provided by NETGEAR. This includes the complete kernel sources.

Ok, I've found the header files in ../linux-4.1.30-armada/include, but there are slightly differnt from those under /usr/include
and so make, or make modules fails with lot of errors such
root@NAS:/DATA/kernel/linux-4.1.30-armada# make modules CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: 'include/generated/mach-types.h' is up to date.

EDIT:
found the problem, include/ lacks an asm/ so
ln uapi/asm-generic/ include/asm -s
does the trick and 'make' runs smoothly now!
