HOW-TO: Compile Custom Kernel Modules
This example is using my setup, which happens to be a RNDU6000 which I upgraded from 4.x to be able to run 6.x OS (http://www.readynas.com/forum/viewtopic.php?f=35&t=70323) I'm creating this becaus...
Great tutorial. I've been working on cross-compiling for ARM platforms, because who wants to compile an entire kernel on an ARM?
Basic steps are the same, I used the ReadyNAS App Development VM available from:
http://apps.readynas.com/pages/?page_id=127
Your modules will be available in /tmp/build/modules. For simple modules such as USB serial and such you should be OK with just copying the modules over, however more advanced things (iptables NAT for instance) require replacing the kernel as well.

Good morning,
I'm looking at how to compile kernel modules following your instructions, however I run into a bunch of issues:
- if using local compilation on the NAS itself, the make command exits as it cannot find the cross compile toolchain (which is odd, since I'm using local compile...)
- when trying to use the ReadyNAS VM you reference:
- basic apt-get commands fail, trying to resolve a link which apparently does not exist anymore (even a simple apt-get install man-db fails). Likewise, apt-get update fails on several IP (which however do resolve)
- the link to the cross compiler you indicate below does not exist anymore...
Any help would be welcome
Thanks
Vincent
