Hello, I am using ARM64 Gentoo on Raspberry PI 3B+ from this project: https://github.com/sakaki-/gentoo-on-rpi3-64bit .
My system do not use graphics interface and also I removed networkmanager (I don not start this service) and IPv6.

[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]

But for RPI3 system I needed Wi-Fi in access-point mode. So I was following this manual: https://wiki.gentoo.org/wiki/Hostapd
My current configuration for hostapd and net are:
/etc/hostapd/hostapd.conf:

Code: Select all

routes_wlan0="default via 192.168.66.1"
rc_net_wlan0_provide="!net"

Unfortunately when I tried to start hostapd service the I received following outputs:

I don know why the wlan0 mode not switch into AP mode and it is still trying looking for access points.
When I run hostapd manually i received following debug message (hostapd /etc/hostapd/hostapd.conf -d):

I don't know what I was missing. Which kernel module I should also install? Which network driver I need or don't need also in /etc/conf.d/net? Which services I need to disable on start?

Hi janbielanski,

sorry to hear you are having problems with this ><

As a first step, please note that to make it lawfully redistributable, the image has been created with the bindist USE flag set globally. This impacts many of the (encumbered) algos required for successful operation of e.g. hostapd.

So, if you try unsetting this flag globally (in /etc/portage/make.conf) and re-emerging, you may have better luck.

Problem has been solved. The source of problem was configuration file:

Code: Select all

# DNS Domain
dns_domain_lo="astro-pi64.org"

# CONFIG eth0 [network access]
config_eth0="dhcp"

# WIFI ACCESS POINT
# ** network connection
#modules_wlan0="wpa_supplicant"
#config_wlan0="dhcp"
# ** access point
modules_wlan0="[b]!iw[/b] !iwconfig !wpa_supplicant"
config_wlan0="192.168.66.3/24 brd 192.168.66.0"
routes_wlan0="default via 192.168.66.1"
rc_net_wlan0_provide="!net"

I missed to exclude completely iw interface (!iwconfig is not enough, I have to exclude also !iw).
I had seen this mistake when I tried to setup AP on on computer for testing.

I wonder how you figured out to use !iw because we don't have to use it with x86_64 gentoo.
