I have a D-Link DWL-120+ USB wireless card. I know. Get a better card :) But this is for a MythTV box and I'm fresh out of PCI slots and money :) The price was right (free) so I figure a little blood and sweat never hurt anyone.

The problem is that I have emerged acx and acx-firmware but when I plug in the USB card, or try to run modprobe acx I get the following:

Code:
mythdawg ~ # modprobe acx
FATAL: Error inserting acx (/lib/modules/2.6.15-gentoo-r1/net/acx.ko): Unknown symbol in module, or unknown parameter (see dmesg)
mythdawg ~ #


dmesg then shows:

Code:
acx: Unknown symbol iw_handler_set_spy
acx: Unknown symbol iw_handler_get_thrspy
acx: Unknown symbol wireless_send_event
acx: Unknown symbol iw_handler_get_spy
acx: Unknown symbol iw_handler_set_thrspy


Any ideas on what is wrong? I am using the masked acx package (0.3.35_p20060521, but tried the stable package with the same results.

Thanks!

Tim

It seems to be a mismatch between the version of acx you have emerged and 2.6.15-gentoo-r1.

Here, for instance, running
Code:
find /usr/src/linux-2.6.17-gentoo-r5 -name \*.c|xargs grep iw_handler_set_spy
gives lots of hits, for example,
Code:
/usr/src/linux-2.6.17-gentoo-r5/net/core/wireless.c:EXPORT_SYMBOL(iw_handler_set_spy);
You either have to update your kernel or downdate your version of acx. [edit: portage shows that 'downdate your version of acx' won't help, you've already tried the lowest version]

Yeah, that's the problem. Since this is a MythTV box, only certain kernels work with some of the modules needed to use MythTV properly. What I don't understand is that if I build acx from source, that shouldn't be a problem should it?

Either way, I'll take another look at the your suggestions when I get home. I guess one option is to try all the releases and build from source to see if one works :)

From http://acx100.sourceforge.net/wiki/ACX it looks as though this will solve your problem. It talks about needing a kernel 2.6.10 or later and getting kernel header files and this usually means that it will accomodate itself to what it finds.

Best of luck!
