The error implicit declaration of function means that a function is referenced (used) before its declaration or when the function prototype is missing. Looking at the source code of compat-wireless-3.1.1-1 it seems the prototype of function br_port_exists is in the header linux/compat-3.1.h but this header is not included in util.c. I would try to add the proper include line (see text in bold) among the others in net/wireless/util.c:

Code:

#include <linux/bitops.h>
#include <linux/etherdevice.h>
#include <linux/slab.h>
#include <linux/compat-3.1.h>
#include <net/cfg80211.h>
#include <net/ip.h>
#include "core.h"

If this solves the issue, you may consider to submit a bug report to the developers of compat-wireless.

i have not this file !

Code:

/usr/include/linux/compat-3.1.h

It's not a system file. The path is relative to the compat-wireless installation directory, that one you extracted from the downloaded tar.gz. If you look at the other include statements, you can see they refer to:

Code:


<path-with-extracted-tarball>/compat-wireless-3.1.1-1/include/linux/bitops.h
<path-with-extracted-tarball>/compat-wireless-3.1.1-1/include/linux/etherdevice.h
<path-with-extracted-tarball>/compat-wireless-3.1.1-1/include/linux/slab.h
<path-with-extracted-tarball>/compat-wireless-3.1.1-1/include/linux/compat-3.1.h

Fixed ... !
I patch this files :
mac80211.compat08082009.wl_frag+ack_v1.patch
channel-negative-one-maxim.patch

comment lines from : compat-wireless-3.1.1-1/net/wireless/nl80211.c

Code:

if (!use_4addr) {
     if (netdev && br_port_exists(netdev))
       return -EBUSY;
     return 0;
}

and this file : compat-wireless-3.1.1-1/net/wireless/util.c

Code:

if (br_port_exists(dev) &&
       (ntype == NL80211_IFTYPE_ADHOC ||
        ntype == NL80211_IFTYPE_STATION ||
        ntype == NL80211_IFTYPE_P2P_CLIENT))
     return -EBUSY;

compile and worked ... !
