   Hello,

   I am still working on getting my CAN interface operational.

   I am using Intel EG20T chipset and I now have the i2c-eg20t module loaded on boot. It does appear when I type lsmod so this is good.
   I managed to install can-utils and now I must install can modules for linux.

   I have downloaded them from the linux-can project [https://gitorious.org/linux-can/] but receive an error when running make (I attached output and error as text files)
   If I attempt to make directly from the driver folder, I receive the error
   "/usr/src/linux/include/linux/linkage.h:5:25: fatal error: asm/linkage.h: No such file or directory"
   I updated kernel source via /usr/bin/get-linux-source and receive same error.

   Not sure how to proceed.

   Any suggestions?

   I was under the impression that these CAN modules should be included in this kernel (3.2.53)

   however, when I type
   modprobe can
   or any variant (can-dev, can-raw)
   I receive error that the module cannot be found.

   if I try to set can0 via
   iplink set can0 up type can bitrate 250000
   I receive error "iplink: either "dev" is duplicate, or "type" is garbage"

   Hopefully this is helpful

   I found that CAN modules were not included in the kernel.

   I downloaded sources, made necessary changes using menuconfig, and am now having issues with making bzImage...

   I type make bzImage and it runs ~30 minutes and then I receive errors on
   drivers/block/loop.c
   This error appears for several functions within loop.c
   "error: 'struct loop_device' has no member named 'lo_backing_virt_file'"
   Followed by
   make[2]: *** [drivers/block/loop.o] Error 1
   make[1]: *** [drivers/block] Error 2
   make: *** [drivers] Error 2

   Not sure what I am doing wrong.

   I set up a VM on a more powerful computer so I can compile faster and try different things to get going.

   I seem to receive kernel compile error no matter what I do...
   This is a fresh install of SliTaz Cooking Core.
   Recharged and updated all packages.
   Installed slitaz-toolchain, ncurses-dev, perl, linux-source.
   Ran get-linux-source
   make oldconfig && make prepare
   make menuconfig
   At this stage I just set =m on the few CANbus network devices I require
   then I've tried just make or make bzImage, both give same error.

   I am lost :C
