Hi All, After downloading the can-tests sources from: http://svn.berlios.de/wsvn/socketcan/trunk/test/?rev=877&sc=1
I ran it on my machine running the following kernel and headers:
# uname -a
Linux 2.6.27.15-2-default #1 SMP 2009-02-09 15:38:31 +0100 x86_64 x86_64
x86_64 GNU/Linux
# rpm -qa | grep header
linux-kernel-headers-2.6.27-2.18
The following config options are set in the running kernel:
# grep -i can /boot/config-2.6.27.15-2-default
CONFIG_CAN=m
CONFIG_CAN_RAW=m
CONFIG_CAN_BCM=m
# CAN Device Drivers
CONFIG_CAN_VCAN=m
# CONFIG_CAN_DEBUG_DEVICES is not set
# CONFIG_SCSI_SCAN_ASYNC is not set
CONFIG_SCSI_WAIT_SCAN=m
# ATSC (North American/Korean Terrestrial/Cable DTV) frontends
/sbin/ifconfig provides below:
# /sbin/ifconfig

Now when i run:
./run_ltp-can_tests.sh
script (created inside the tarball), it gives me the following error:
socket: Protocol not supported
socket: Protocol not supported
Since the latest kernel is installed with the headers, the build works
fine. Is there any other dependent config option(s) needs to be set to
make this work ??
