I tried with master, 2.3.0d5 and 2.2.2

[lennart-bader]

Did you find a solution?

[svenchen90]

Do shown below before installing mininet

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade

[crisbermud]

Installation script isn't working well for me as well. I tried to install Mininet 2.2.2 and 2.3.0d6 on Ubuntu 20.04.1 but cbench component always failed with the following error related to liboflops_test.

I couldn't fix the error so just skip installing it...

[ishitachaturvedi]

I am facing the same issue, was it resolved?

[lantz]

Tested and working in 2.3.0b2.

[tobiayofe]

I'm experiencing this same issue please. I'm using mininet version 2.6.

[lantz]

2.6? Current Mininet version is 2.3.1b1; last release was 2.3.0.

[tbarbette]

With the latest version, 2.3.1b1, the problem is fixed with 20.04 LTS for me at least :)

Well I'm using an Ubuntu variant called Lubuntu and it's Ubuntu 20.04 LTS. I ran the command below:
"sh ./boot.sh ; ./configure --with-openflow-src-dir=/oflops/openflow/; sudo make" OR
sh ./boot.sh ; ./configure --with-openflow-src-dir=/oflops/openflow/; make"

Both of them results in the images below:

I just used the OS package for openflow.

I just used the OS package for openflow.

So you don't use Cbench or other performance benchmarking tool on it?

[tbarbette]

Not sure what you're referring to. I'm the OP of this issue. A few years ago I could not compile mininet on Ubuntu 18.04. And with time it was fixed. Nothing really related to ovs here.

Well, my complaints here wasn't about openflow or mininet from the on set. I was complaining about an error due to Cbench installation on a mininet VM instance.

Perhaps, I have made complaints in the wrong box. I thought seeing oflops was about Cbench which is the main directory for the Cbench cloned to the mininet VM.
