mnexec.c Compilation issue

Hi, I need to compile mininet-wifi. During the '''step 4: $ sudo util/install.sh -Wlnfv''', i got the following error:

It's like VERSION is not recognised as a global variable How I can workaround this issue ? Thanks for any tips and i can provide further informations if needed. Cordialy

Hello,

I suggest you doing a clean installation. I cannot reproduce the issue.

If you need recompiling the code you should run sudo make install

I just took a clean Ubuntu 22.04, cloned the repo, then it's still the same )-:

[ramonfontes]

This error occurs when a constant string or text is not closed in double quotes; when we have missed closing quotes; or even using single quote instead of double quote while closing the string/text. AFAIK, that's not the case with mnexec.c. I just did a clean installation and I was unable to reproduce the issue.

Which gcc and python versions do you have?

[StatelessCat]

Ok, here are my versions:

$ python --version
Python 3.10.6
$ gcc --version
gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0

Well, I have the same versions. Honestly, I have no idea what is going there.

Just successfully did a new clean installation on a new machine and on a docker container.
