Re: socketCan build fails

[Gabriel Manriquez <gmanriquez@wegmannusa.com>]

Hi Oliver,

I'm running kernel version 2.6.35.11.

I was just following the README file which says to compile 
kernel/<version> ... so since you're saying that I don't need to then 
can I just go ahead and compile the utilities and test programs?
I'm trying to use socketcan in conjuction with can driver : 
peak-linux-driver-7.4 which I already installed.
At this point I just need to test communication to and from my CAN 
device via usb and I thought I needed the socketcan utiliites/test 
programs to do that.
The peak-linux-driver-7.4 driver comes with receive and transmit test 
utilities but they're not suitable for my type of driver install  "NETDEV"
I hope what I'm saying makes sense.  Otherwise please ask.


Thanks,

-Gabriel
