hi,
for a specific need, I try to install ovs_2.13.0 on openwrt.21-stable, however this version of ovs is not placed on packages. so I try to buil it from source, but dependcies need to be installed first ans I even stuck at building dependcies due to they are not in the package list also.
anyway my question is, is there any other way to achieve installing ovs.2.13.0 without building every packet from scratch. Im not an software-eng/coder/scripter..
thanks.
Is there a reason why you want an earlier version?
I just built it on aarch64 on OpenWrt master. What dependencies are you missing on OpenWrt 21?
hello VA1DER,
there will be a SDN controller that support specific ovs release as 2.13.0.
unfourtanetly, I need to built it on openwrt machine. I dont try to build an image with ovs2.13.0, but I want to try. but this is not my case.
by the way, Im getting following lines inluding errors.
thanks.

EDIT: The following only addresses the later issue. The earlier write error, I don't know. I suspect it's likely another missing tool. I would suggest you look at the link in option three below to the wiki page I wrote, and follow its instructions for setting up your device to build OpenWrt on - specifically on installing all the coreutils and other build tools.
Oh, yes, rev is a util-linux tool that OpenWrt is missing. You can do one of three things:
-
Use a pre-built
revbinary:
https://va1der.ca/~public/openwrt/bin/aarch64/rev -
Build the rev tool, which is one of the tools in
util-linux, inside OpenWrt - inside your devel folder do the following (you might need xz and full version of tar for this)
The patch is just a quick and dirty one to allow you to disable all the other utils and enable only rev (the configure for util-linux doesn't otherwise let you enable rev by itself)
wget https://mirrors.edge.kernel.org/pub/linux/utils/util-linux/v2.39/util-linux-2.39.tar.xz
tar -xaf util-linux-2.39.tar.xz
cd util-linux-2.39
wget -O - -o /dev/null https://va1der.ca/~public/openwrt/patches/util-linux/util_linux_enable_rev.patch | patch -p0
./configure --prefix=/usr --without-systemd --without-btrfs --without-econf --without-util --without-tinfo --disable-all-programs
make rev
- Follow these instructions for building OpenWrt ON OpenWrt, which builds
revas part of that procedure.
Thanks Mr Fitzner,
Your response was very informative, and I was able to successfully build and install "rev" by the steps you provided. Thank you very much for your assistance. You've been incredibly helpful.
rev is now a commad on my OpenWRT machine. 
to install rev, I follow your instructions, these are my commands that I applied:
opkg update
opkg install pkg-config make gcc diffutils autoconf automake check git git-http patch libtool-bin
opkg install grep rsync tar python3 getopt procps-ng-ps gawk sed xz unzip gzip bzip2 flock wget-ssl

cd util-linux-2.39

./configure --prefix=/usr --without-systemd --without-btrfs --without-econf --without-util --without-tinfo --disable-all-programs
make rev
make install
Additionally, I attempted to configure/make/make-install once more and carefully inspected the outputs of these commands. As a beginner, I didn't observe any errors, but unfortunately, I'm still unable to access the ovs commands, 
.
So you compiled ovs and it seemed to install, but you can't access it?
When you ran the configure script for ovs, did you tell it to use /usr as the prefix? Most GNU configure scripts will pick /usr/local as the default installation directory, and I don't think /usr/local/bin is in the search path on OpenWrt normally.
Try going back to the openvswitch-2.13.0 directory and performing:
make uninstall
configure --prefix=/usr
make clean
make -j $(nproc)
make install
The first make uninstall is to remove the earlier installation, assuming it was installed to /usr/local/. Then the rest is just reconfiguring it for /usr, rebuilding, and reinstalling. After that, all the ovs commands should be available.
Great!
Mr. Fitzner, thank you so much. I really appreciate your help!
I applied the solution you provided, and it worked!!!
Now I have access to all the ovs commands:
root@qemuOpnWRT:/# ovs
ovs-appctl
ovs-bugtool
ovs-bugtool-daemons-ver
ovs-bugtool-fdb-show
ovs-bugtool-get-dpdk-nic-numa

ovs-bugtool-ovs-ofctl-loop-over-bridges
ovs-bugtool-ovs-vswitchd-threads-affinity
ovs-bugtool-qos-configs
ovs-bugtool-tc-class-show
ovs-check-dead-ifs
ovs-ctl
ovs-docker
ovs-dpctl

ovs-testcontroller
ovs-vlan-test
ovs-vsctl

Now, I'm going to locate the openvswitch module as requested to start it. 
root@qemuOpnWRT:/# ovs-ctl start

First of all, I see I made a little mistake with your configure, though that's not likely causing your problem. I didn't notice that the configure script is a little dated and that it uses the prefix for etc. Right now it's looking for your configuration in /usr/etc. So let's fix that - you'll have to reinstall again, sorry. Switch to the devel folder and:
make uninstall
./configure --prefix=/usr --sysconfdir=/etc --sharedstatedir=/var
make clean
make -j $(nproc)
make install
As for your problem, it looks like you don't have the kernel module installed. I'd suggest trying to use the one included with OpenWrt first:
opkg install kmod-openvswitch
If that doesn't work for you, then you'll have to build the kernel module too, which will be more complicated.
Dear Mr. Fitzner,
