OpenWrt na Asus wl 500b

* first upgraded firmware to 1.8.2.4 from asus web
* then downloaded install cd for router from asus web. Unfortunately only for windows and did not work through wine. Had to run it on windows machine.
* used ‚upgraded firmware‘ utility to upload this image:
openwrt_8_09_2-brcm-2.4-squashfs.trx
* now I can login to it through web (login root, password empty), and configure basic stuff (ip, name, password)
* Then I logged in through ssh root@192.168.1.1
Linux 2.4.35.4 #12 Tue Dec 29 15:30:20 UTC 2009 mips unknown

* Installed basic packages through ‚opkg install <balicky>‘

* snd-usb-audio did not work well, heard only sharp noise, so I went by:
https://forum.openwrt.org/viewtopic.php?id=13131
and I uninstaloval kmod-usb-audio
installed kmod-alsa
and did rmmod snd-usb-audio
then sound replay worked through:
wget -q -O – http://live.slovakradio.sk:8000/FM_128.mp3 | madplay -o /dev/sound/dsp –
wget -q -O – http://live.slovakradio.sk:8000/FM_128.mp3 | madplay –

configure, LDD, using so library

error while loading shared libraries: cannot open shared object file: Error 40
(link to it is wrong, ll on it)

error while loading shared libraries: cannot open shared object file: No such file or directory
( it is not in the system, add it)

so you want to use .so library from internet.
first – library is probably not stored in system path.
use ‚locate thatlib.so‘. If nothing is printed – it is not in the system.
Add it:

sudo ln -s $PWD/libmylib.so.666 /usr/lib/libmylib.so

then fix up the locator:

sudo updatedb

and test locator

locate libmylib.so

you can also try to see if its dependencies are met:

ldd libmylib.so

That’s it.
