I have a 7350 with a TS-CAN1 on it. No problems loading the kernel module, but
now that I'm starting to write code, I am having problems linking to libvca.
I'm using precompiled lincan-7800.
Here's the output from running make (run on the 7350):
ts7000:/mnt/nfs/node_controller# make
gcc -Wall -I/usr/include/lincan -lpthread -L /usr/lib/lincan -lvca main.o
ParseCommand.o CreateTCPServerSocket.o AcceptTCPConnection.o HandleTCPClient.o
TCPSocketServer.o DieWithError.o CANBus.o -o arm_nodecontroller
CANBus.o: In function `CANInit':
CANBus.c:(.text+0x2c): undefined reference to `vca_open_handle'
collect2: ld returned 1 exit status
make: *** [arm_nodecontroller] Error 1
CANBus.c is pretty simple right now - I didn't make it very far before running
into issues!
/* CANBus.c */
#include <stdio.h>
/* lincan headers */
#include <can_vca.h>
struct canmsg_t canmsg;
int CANInit(void)
{
vca_handle_t canhandle; //create a handle to the can device
const char *candev = "/dev/can0";
printf("Opening %s\n", candev);
/* open the can device */
if ( vca_open_handle(&canhandle, candev, 0, 0) != VCA_OK) {
perror("open");
exit(1);
}
}
