Undefined Reference on Ubuntu 23.10
Hello
I'm in the process of integrating the PF_RING library into a CMake project, but I'm facing compilation errors. I've followed the steps described in this guide to install PF_RING.
Please let me know if you need more information. P.S.: I didn't have any issues installing the PF_RING library, and compiling the examples

I am not a cmake expert, however I see compilation is failing because it cannot find symbols from libpcap
Hi @cardigliano
Before creating this issue, I tried with a static link to libpcap, and encountered the same error. I've just identified the problem, it's related to the nl libraries. CMake can't locate the libraries on the Raspberry Pi, so I had to add a static link to where these libraries are located. However, now I'm getting the following error:

Regards!
Hi @cardigliano
Sorry for not updating the thread earlier, but I have already fixed the issue. The problem was due to some paths related to the Raspberry Pi architecture not being in the default directory for CMake, which caused the conflicts mentioned in my previous message
Thank you
