Sorry that does not work for me - wish it did ! - I get the same error after trying to compile the source. Im using ubuntu 4.4.0-34-generic -specifically the error is

Since I am a noob trying to get ipfw to work on Linux - Ubuntu 14.04 to be precise, I would very much appreciate some noob level (lead me by the nose type) help.

Bump... does anyone have an idea what the issue is ?
A more recent attempt with 4.4.0-36-generic linux headers (Ubuntu 16) yielded these specific errors (and more)..............

Hi

I m observing a similar issue while trying to build dummynet. Any suggestions will be helpful.

Thanks

Perhaps our colleagues at the University of Pisa can help us. I think the problem starts with the version of linux that is supported. Alas ! I have had no problems until the headers exceed 3.x.x.x. Since I am merely a novice (at best) I defer to the genii in this community ;)

I was worried it was 3rd declension fortunately it is not http://www.cultus.hk/Latin_vocab/noun1245/genius.html

I am facing the same issue. Does anyone have a resolution ?
