solution for compiling the broadcom 431* driver in linux kernal 3.10 and above

English Hardware
#1

In linux kernal 3.10 and above，the function “create_proc_entry” has been removed.
so the broadcom 431* driver can not be compiled correctly.
The solution is to make some modifications to the “static int
wl_reg_proc_entry(wl_info_t *wl)” function in “src/wl/sys/wl_linux.c”.
Modify it as below:
//-------------------start of code-------------------------------------------------------------
static int
wl_reg_proc_entry(wl_info_t *wl)
{
char tmp[32];
sprintf(tmp, “%s%d”, HYBRID_PROC, wl->pub->unit);
// hack code to fit kernel 3.10.0 above
#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 10, 0)
if ((wl->proc_entry = create_proc_entry(tmp, 0644, NULL)) == NULL) {
WL_ERROR(("%s: create_proc_entry %s failed
“, FUNCTION, tmp));
ASSERT(0);
return -1;
}
wl->proc_entry->read_proc = wl_proc_read;
wl->proc_entry->write_proc = wl_proc_write;
wl->proc_entry->data = wl;
#else
static const struct file_operations wl_proc_fops = {
.owner = THIS_MODULE,
.read = wl_proc_read,
.write = wl_proc_write,
};
if ((wl->proc_entry = proc_create(tmp, 0644, NULL,&wl_proc_fops)) == NULL) {
WL_ERROR((”%s: create_proc_entry %s failed
", FUNCTION, tmp));
ASSERT(0);
return -1;
}
#endif
return 0;
}

//-------------------end of code-------------------------------------------------------------

After this change,you can follow the readme tutorial to compile and install the driver correctly.

Please use CODE tags around your copied/pasted computer text. You get them by clicking on the # button in the tool bar of the post editor.

#3

Or you could just use the RPM packages from Packman.
They contain a more sophisticated patch btw:
