My guess is that it’s failing to build the Makefile properly, perhaps some values are not included. I know one of the errors is that python cannot locate g++ in ./configure even though it’s installed so CXX=/usr/bin/g++ took care of that, but didn’t change the error much.

I wonder if there is just some problem with the libpcap conan package on your system and/or Fedora 35. I’m not sure if there’s much else I can do here, especially because I can’t reproduce the problem on Fedora 36. I think the originally reported issue caused by DOS line endings has been resolved.

I have confirmed that the original build issue has been resolved as I was able to build it successfully without libpcap. I’m fine with closing this issue because it seems to be a weird isolated case to my system. I’m not sure why it’s even trying to build libpcap since I have the exact version it’s targeting already installed…

If anyone else is having the same issue, just install the dependencies manually and build without conan:

mkdir build && cd build
cmake ..
cmake --build ..
