How to set up Realtek 8187 in Access Point mode?

Hi,
I have 2 USB WiFi Adapters, one with the RTL8187B chipset, the other with the RTL8187L chipset(it's an ALFA AWUS036H)
I want to set up any one of them as an Access Point, but I don't really know which driver to use and how to do it
When I try this command:
wlanconfig wlan0 create wlandev wifi0 wlanmode ap
I get an ioctrl error.

Thanks in advance for the help!

Re: How to set up Realtek 8187 in Access Point mode?

Here is the error, since I wasn't' at my desktop when I made the topic:
wlanconfig: ioctl: No such device

EDIT:
I've reached this page:
http://wireless.erley.org/stable.html

I'm trying to build compat-wireless from AUR, but it always fails while compiling.
Any ideas?

I managed to install compat-wireless by building it directly from tarball on linuxwireless.org, but I still get this error:
[root@lesiroth-desktop ahmad]# iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Invalid argument.

Apparently I need to have Master shown when I run this:
[ahmad@lesiroth ~]$ iw phy phy0 info
