Hi,

What are the other configure options you're using? Following http://www.read.cs.ucla.edu/click/nsclick for NS 3 it works for me. Did you try a "make distclean" before too? I recently submitted a PR which moved fasttcpflows from linuxmodule to be compatible with userlevel. Maybe the old fasttcpflows.cc/hh is still in your elements/linuxmodule folder which would prevent tcpudp/fasttcpflows.hh from being included?

I had a related issue with this build (2a181e0). I used EC2 instance clean, followed the instruction in INSTALL and got the following error. I found that this build (392b1f6) was able to make following the instructions.

[tbarbette]

Is it solved by the commit #199? If so, please close the issue ;)

[lthurlow]

Tested on fedora I do not guild a build issue with --enable-nsclick. I think you can close this one, I will open another one for --enable-all-elements.

[fabian-marquardt]

Sorry for my long absence, I was busy with other projects. Just to let you know, the issue is fixed on my system when using the recent master branch.
