Error in including IEEE802154.h

Error in including IEEE802154.h

[Matteo Petracca]

Dear all,
I gave a program in kernel 3.8.17 in which I successfully include
ieee802154.h by simply witing:

#include <ieee802154.h>

In my BeagleBone now I have just upgraded the kernel to 4.0.1,
and compiling the same code I get:

fatal error: ieee802154.h: No such file or directory

Any hint?

Best,
Matteo

no, I suppose that this header is some of the old netlink interface, but
I can't be sure here. I can't be sure because I don't know what was the
functionality/why you need  that in your application.


In short:

We don't deliever any headers to uapi for userspace. If you need headers
for userspace<->kernelspace communication you need to grab them on your
own out of your current kernel source tree. What I mean is that we
didn't change any in our uapi headers which are deliviered by
kernel-headers because we don't have any headers which laying inside
"include/uapi" tree right now.

Hi,
the program that I am trying to compile is the test1.c
in the lowpan-tools.

#include <linux/sockios.h>
#include <net/if.h>
#include <sys/ioctl.h>
#include <sys/socket.h>
#include <stdio.h>
#include <stdint.h>
#include <string.h>
#include <unistd.h>

#include "ieee802154.h"

int main(int argc, char **argv) {
     int ret;
     char *iface = argv[1] ?: "wpan0";

     char buf[] = {0x40, 0x00, 0x56};
     int sd = socket(PF_IEEE802154, SOCK_RAW, 0);
     if (sd < 0) {
         perror("socket");
         return 1;
     }

     ret = setsockopt(sd, SOL_SOCKET, SO_BINDTODEVICE, iface, 
strlen(iface) + 1);
     if (ret < 0)
         perror("setsockopt: BINDTODEVICE");

     ret = send(sd, buf, sizeof(buf), 0);
     if (ret < 0)
         perror("send");

     ret = recv(sd, buf, sizeof(buf), 0);
     if (ret < 0)
         perror("recv");

     ret = shutdown(sd, SHUT_RDWR);
     if (ret < 0)
         perror("shutdown");

     ret = close(sd);
     if (ret < 0)
         perror("close");

     return 0;

}

It worked in kernel 3.8.13 on BBB, now I get the error

test1.c:35:24: fatal error: ieee802154.h: No such file or directory

in kernel 4.0.1.

you know what this code does?

It search at first in the local dir where "test1.c" is stored for the
"ieee802154.h" header. Which means it's a local header.

A fallback behaviour of gcc will search this header in your given
include path which are given by -I and -stdinc gcc arguments.


What I can told you now that we don't deliver any headers into userspace
side with the kernel-headers. So this header comes from the lowpan-tools
package. Maybe tyoe a `find -name "ieee802154.h" $LOWPAN_TOOLS_DIR` in
your shell, to find it or whereever your include paths belongs to which
are given over "-I" of gcc call.
