in thread Help with Lorcon XS library

could you please test in your computer if it works?

No, I'm not prepared to go to those lengths.
But it if you're prepared to try things and give us useful feedback on what's happening then I (or someone else) might be ble to come up with some helpful diagnosis.

For example, what output do you get if you run: 
use strict;
use warnings;
use Net::Lorcon2 qw(:subs);

my $driver = "iwlwifi";
my $if = "wlo1";

my $drv = lorcon_find_driver($driver);
if (! $drv) {
   print STDERR "[-] Unable to find DRV for [$driver]\n";
   exit 1;
}

my $lorcon = lorcon_create($if, $drv);
if (! $lorcon) {
  print STDERR "[-] lorcon_create failed\n";
  exit 1;
}

If all goes well, it should produce no output.

Update: Another one that might be helpful to run is the following (from the examples that ship with Net-Lorcon2-2.03 source): 
use strict;
use warnings;

use Net::Lorcon2 qw(:subs);

my @cards = lorcon_list_drivers();

use Data::Dumper;
print Dumper(\@cards);

    Hi, unfortunately the program dies (I've already done some test and i am not surprised) the die message is:  [-] Unable to find DRV for [iwlwifi] update Hi again, the problem persists only in the 2 functions ( lorcon_find_driver and  lorcon_create , some functions ( like the lorcon_list_drivers ) works properly while other which need the $context ( aka the  Net::Lorcon2::lorcon_create) crashes ( I think the problem is linked to the  lorcon_create. regards Edoardo M.

      some functions ( like the lorcon_list_drivers ) works properly

      I don't know much about Net::Lorcon2, but I'm guessing that the string that you assign to $driver must be the same as one of the strings listed by lorcon_list_drivers().
      What happens if you assign those strings (as shown by Dumper(\@cards)) to $driver ?
      Could you provide us with the output of Dumper(\@cards) from that second program I posted.

      Cheers,
      Rob

        If this is the lorcon in question:

        Current State:
The lorcon2 rewrite currently only supports the mac80211 driver,
additional drivers will be restored over time

        Hi the output of the 
         lorcon_lsit_driver is:
$VAR1 = [
          {
            'name' => 'rtfile',
            'details' => 'Real-time PCAP file source'
          },
          {
            'details' => 'PCAP file source',
            'name' => 'file'
          },
          {
            'name' => 'madwifing',
            'details' => 'Linux madwifi-ng drivers, deprecated by ath5
+k and ath9k'
          },
          {
            'name' => 'tuntap',
            'details' => 'Linux tuntap virtual interface drivers'
          }
        ];

        I have already tried if I use: 
         
  print Net::Lorcon2::lorcon_create("wlo1", $driver); #where $driver c
+an be madwifing or other it says:
  
  Net::Lorcon2::lorcon_create: driver is not a reference at -e line 3.

        [download]
        and if I do 
           print Net::Lorcon2::lorcon_create("wlo1", \$driver); #where $driver
+ can be madwifing or other it says
   segmentation error (core dump created)
