Fix for the /opt/bin/update-alternatives problem!!!

Hi Gizmo1007!

The error is the way you stated 'Syntax error' also the expected result after change.

The problem was that: install of uclibc-opt first, then reinstall busybox and then do the edits per sollie's info did not work for me. Struggled for hours with it different solutions and that didn't work got the error everytime. Tried to downgrade to 1.5.1-1 didn't work either. The qualified path to the right busybox command 'head' in the 'update-alternatives' did it for me. The default 'head' command came from the wrong busybox (probably the one ASUS shipped it with)

Rejan.

Finally! Thanks everyone for the help.

Usage: ln [OPTION] TARGET... LINK_NAME|DIRECTORY

I tested it and it works: ln -s /opt/bin/busybox /opt/bin/head
It seems busybox checks the arg[0] (program name, in this case head) to see the command. If I create that link I get the correct help:

Busybox 1.7.2 ....
Usage head [OPTION] ...

On a slightly different tangent,

Does anyone have a problem when running ps command with busybox 1.7.2
I can only run ps -w
nothing else will work.
Is there another way to check what process are being executed currently.
I know it's supposed to be ps -x but busybox won't allow me to run that option, only gives -w as available
any other commands that do the similar?

if you install procps ipkg you will get fully functional ps

thanks for last pointer it worked out,

One final problem which I have noticed since installing busybox ver 1.7 is that when I power down the unit and repower again windows cannot see the WL700 as a share drive.
You can see ushare as a media server but cannot see WL700.
When I reset the unit it comes up fine.
Question is there any way in rc.local to correct this?

sorry... now it works

Maybe superfluous, but the original title Sollie gave: Fix for the /opt/bin/update-alternatives problem!!!, did not tell me very much, when I first saw it. I really never had heard of update-alternatives. Hence, also not of any problem arising from it...

But, after installing a new package with ipkg these days, which I had not done for months, gave me all sorts of syntax errors and post-errors, as with so many people here.
But NOW I understand that's because the newer ipkg scripts in /opt/bin/update-alternatives use /bin/sh in stead of /opt/bin/bash. AHA.

I changed step 2 and 3 from Sollie in:
2: ln -s /opt/bin/busybox /opt/bin/sort
3: ln -s /opt/bin/busybox /opt/bin/dirname
and added:
3b: ln -s /opt/bin/busybox /opt/bin/head

Now ipkg does its job fine.
So I guess this is the final recipe (partly), let alone that if you run K.C.Furge's latest 1.0.7.8 firmware with KCSHELL set, this should not be needed anymore.:p

Hi there,


a good advice for anyone who has kfurge custom firmware and has ever encountered this problem, above steps will not work, if your environment variables PATH and LD_LIBRARY_PATH are not set properly before!

You must apply:

export PATH=/opt/bin:${PATH}
export LD_LIBRARY_PATH=/opt/lib:${LD_LIBRARY_PATH}

guess i'm stuck and considering to do a complete reinstall after failed upgrade.
changes made, still get the following errors, symlinks do not work... maybe someone found a fix here?

ipkg upgrade

Maybe there is nothing wrong. I had installed wget, that conflicts with wget-ssl. Now I removed wget, and installed wget-ssl. That conflicts with wget, but that is just informative, because wget is not there anymore. So have a look in the list that ipkg status produces to spot the places with Conflicts.
For instance:

Code:

---

Package: wget-ssl
Version: 1.11.1-1
Depends: openss
Conflicts: wget
Status: install user installed
Architecture: mipsel
Installed-Time: 1207514113

---

and

Code:

---

Package: ivorbis-tools
Version: 1.0-6
Depends: libvorbis, libogg, libao, libcurl, libvorbisidec
Conflicts: vorbis-tools
Status: install user installed
Architecture: mipsel

Can someone post their full, working copy?

Thanks!

Actually it's the update-alternatives config file I need.
