Linux version 3.10.108-dd (root @ linux) (gcc version 7.3.0 (OpenWrt GCC 7.3.0 r6438-46177a850f)) # 54598 Thu Apr 26 02:19:11 Used in CEST 2018.

Once, I used Entware by setting the following as a reference
https://wiki.dd-wrt.com/wiki/index.php/Installin…

After doing opkg update after a long time, if you type opkg, it will output a bus error and it will be an error

Since it is inevitable, refer to the following
https://wiki.dd-wrt.com/wiki/index.php/Installin…

[For MIPS-based devices (Atheros, not dual-core):]

cd / opt (Enter key pressed)
wget http://bin.entware.net/mipssf-k3.4/installer/gen… (press Enter key)
sh generic.sh (press Enter key)

I installed
Typing / opt / bin / opkg outputs a bus error and results in an error ntware-for-kernel-3x / Entware-ng-3x / wiki / General-installation-notes
With reference
https://github.com/Ehttp://entware-3x.zyxmon.org…
And run install_std.sh,
./opkg list
busybox-1.27.2-2
entware-opt-1.0-6
findutils-4.6.0-1
libc-2.25-8
libgcc-6.3.0-8
libpthread-2.25-8
librt-2.25-8
libssp-6.3.0-8
libstdcpp-6.3.0-8
locales-2.25-8
opkg-2011-04-08-9c97d5ec-17a
terminfo-6.0-1c
zoneinfo-asia-2017c-1
zoneinfo-europe-2017c-1

And / opt / bin / opkg execution no longer gives an error

Running after / opt / bin / opkg update will result in a Segmentation fault
How can you give advice?

I am not sure that I follow what you did. Have you tried:

https://github.com/Entware-for-kernel-3x/Entware-ng-3x/wiki/General-installation-notes

[Katu_Ueda]

Am I doing something wrong?
I hope you'll tell me

I downloaded and executed install_std.sh from the URL provided,
and I think that the update of the package list is the same as other entware
(there is no particular description on the corresponding page)

If you think that opkg upgrade should be performed after opkg update,
typing opkg after upgrade will output the following,
so it is excluded from this post

opkg: /opt/lib/libc.so.6: version `GLIBC_2.27 'not found (required by opkg)

Have you read the wiki here: https://wiki.dd-wrt.com/wiki/index.php/Installing_Entware

I wrote it a while ago but it should still be accurate.

opkg update - downloads the latest package list
opkg upgrade - checks the list against your installed packages, looking for upgrades

By the way, the Entware located here, the same one I linked to in the wiki, is the most up-to-date: https://github.com/Entware/Entware

[Wildlion]

agree with ian5142

once the install has happened run

[Katu_Ueda]

I'm sorry, my equipment is a WZR-300HP.
https://wiki.dd-wrt.com/wiki/index.php/Supported_Devices#Buffalo
I don't think that the latest DD-WRT works

So I presented cat / proc / version as a prerequisite

If Entware-3X doesn't work at all, give up,
https://github.com/Entware-for-kernel-3x/Entware-ng-3x/wiki/General-installation-notes
Has an installation shell that can be installed and has a package presentation.
I want to know the suggested way to install the package

Perhaps the subject was bad. Sorry if you should have asked "how to run old Entware-3X on a machine that only runs kernel 3.X"

[Katu_Ueda]

To check, use the ipkg command to find the local ipk file
But my DD-WRT does not have ipkg, disappointed

[ian5142]

Hello,
A very recent dd-wrt build is found here: ftp://ftp.dd-wrt.com/betas/2020/02-14-2020-r42366/buffalo_wzr-300hp/

Use the webupgrade file if the router is already running dd-wrt. If you are coming from a build older then a few months, sometimes even only a few builds ago, reset to factory defaults. Then add in your settings manually, don't restore a nvram backup.

I would highly suggest using the Entware that I linked to, it is still being updated, the other one is not.

[Katu_Ueda]

Somehow, the following thread seems to be helpful
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=314719&sid=1eb86b7e23b798998c0037f29d493242

[Katu_Ueda]

I'm surprised you have the latest build
Thanks for any useful information
Then, I will examine the release notes etc.
Because old love machines do not grow into bricks

[Katu_Ueda]

I could not stand it and updated it
It seems to have been upgraded.
cat / proc / version

However,
Running after / opt / bin / opkg update will result in a Segmentation fault
And
opkg update will output:
./opkg: /opt/lib/libc.so.6: version `GLIBC_2.27 'not found (required by ./opkg)

[Katu_Ueda]

The following message at the time of the update seems like evidence
Upgrading libc on root from 2.25-8 to 2.27-9 ...
Downloading http://bin.entware.net/mipssf-k3.4/libc_2.27-9_mips-3.4.ipk
wget: read error: Connection reset by peer

It can be downloaded with a browser, but is the work area of opkg update too small?

[Katu_Ueda]

If you change the extension of downloaded libc_2.27-9_mips-3.4.ipk to tgz and browse with Archive Manager, you can see the directories and files of / opt / etc and / opt / lib
Should this be placed in / opt? But I doubt that there is a file called control in /

[Katu_Ueda]

opkg worked by changing the extension of libc_2.27-9_mips-3.4.ipk to tgz
and placing the contents in / opt / lib / opt / etc in dd-wrt.
Older packages, simply on platforms
opkg update opkg update is not good
