Problems compiling Hostapd

[junkmechanic]

Hi.

I am quite new to Linux. In fact Quantal is my first Linux OS and the word around the town gives me the feeling that I am not on a good start .
Anyways, to complicate matters I have Broadcom BCM4313 wireless adapter and one of my basic requirements is to get the hotspot working to connect my android to it.

So, as instructed on hostapd site, I tried for the minimal-config to work. It didnt. I got the following error :
'nl80211' generic netlink not found

So I figured that I need to first install libnl libraries. Downloaded the latest tar ball versions of compat-wireless, regdb, crda, libnl and hostapd. Extracted them in /usr/src/ folder. Then I build-compiled libnl, regdb adn crda.

Now in the hostapd folder, I copied the default config to .config (cp defconfig .config). Next, inside .config, uncommented and added the following lines

CONFIG_DRIVER_NL80211=y
LIBNL=/usr
CFLAGS += -I$(LIBNL)/include/libnl
LIBS += -L$(LIBNL)/lib

and tried to compile it. figured a few other libraries were missing that I had to install.
Finally this is what I get.

Any suggestions?
Seemed to have hit a wall.

Thanks for your time.

Hi, not sure but you could try to install libn1

sudo apt-get install libnl-dev

[schragge]

Just to be sure that the hostapd from Ubuntu repository really doesn't contain the driver for your device as the error message

'nl80211' generic netlink not found

doesn't look quite unambiguous to me, could you please try

sudo apt-get install iw
sudo iw list

If iw list fails, you can then in good conscience continue compiling the newer hostapd version from source.

Thanks for your replies @schragge and @spiralsun.

I tried your suggestions. Didnt work. iw list says "nl80211 not found.".
Anyways, more research indicates that I suffer from this disease.
