PostPosted: Tue Jan 14, 2014 3:09 pm    Post subject: How can I build old drivers? Reply with quote

I have been installing Gentoo on iMac DV, an old G3 machine.
The wireless drivers I need, airport and orinoco, are on the installation CD and I can use wifi connection.

However, I cannot build the drivers because they don't appear on the configuration menu on 3.10.7-gentoo.
I tried to add "CONFIG_APPLE_AIRPORT=m" to .config manually with a editor.
However, it seemed to be deleted at the stage of make.

Although I have confirmed the source file of the driver, airport.c in the kernel source,
I cannot find the way how to build the driver for my old iMac.

Please show me the way.

Regards, :(

You are strongly discouraged to do this as, among many things, it just does not automagically care of dependencies.
Code:
$ cat /usr/src/linux/.config
#                                                                                                                                                                                               
# Automatically generated file; DO NOT EDIT.

I cannot really tell about 3.10.7 precisely, however, on my 3.10.24 :

Symbol: APPLE_AIRPORT [=n]
Type : tristate
Prompt: Apple Airport support (built-in)
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Wireless LAN (WLAN [=n])
-> Hermes chipset 802.11b support (Orinoco/Prism2/Symbol) (HERMES [=n])
Defined at drivers/net/wireless/orinoco/Kconfig:56
Depends on: NETDEVICES [=y] && WLAN [=n] && PPC_PMAC && HERMES [=n]

First ensure that all the conditions listed above following "Depends on" are met, then check if this option is available for you at the suggested Location.

Thank you for your quick reply.

I have found the above in drivers/net/wireless/orinoco/Kconfig.
So I checked:

in .config.
However, I could not find any _HERMES in it.

What should I do next?

Hi,

assuming you are using the "make menuconfig" target you can search for config options by pressing SHIFT + / . I assume there are similar options for the other config targets. A search for HERMES reveals:

Quote:

│ Selects: WIRELESS_EXT [=n] && WEXT_SPY [=n] && WEXT_PRIV [=n] && FW_LOADER [=m] && CRYPTO [=y] && CRYPTO_MICHAEL_MIC [=n]


Best Regards,
Holger

Moved from Kernel & Hardware to Gentoo on PPC.

As a G3 is a PPC box

I looked into "drivers/net/wireless/orinoco/Kconfig" and found the following description:

config APPLE_AIRPORT
tristate "Apple Airport support (built-in)"
depends on PPC_PMAC && HERMES

config HERMES
tristate "Hermes chipset 802.11b support (Orinoco/Prism2/Synbol)"
depends on (PPC_PMAC || PCI || PCMCIA)
depends on CFG80211 && CFG80211_WEXT

I checked the above dependencies in .config and found that CFG80211_WEXT was not set.
In menuconfig, I set the CFG80211_WEXT and then Hermes and Airport menus appeared in it.

I could build Apple Airport and Hermes.

Thanks,
