Dear all Pfcount (build from Github) can not reopen zbalance_ipc instances but pfcount installed via apt can

2. System Information:
   • Ubuntu 22.04
   • Pfring version ( install via apt) : 8.8.0-9273

     apt list --installed | grep pfring

@jolysoul127 this is strange as the code and libraries are exactly the same, we will verify this

Thank you @cardigliano Update : I have install fresh ubuntu 22.04 (iso downloaded from Ubuntu Official site) but not solve the problem

• Install requirement

  
  apt-get install build-essential bison flex linux-headers-$(uname -r) libnuma-dev libnl-genl-3-dev
  apt install gcc-12

- Make kernel ( but not make install )
- Make driver 
- make lib and libpcap ( make only, not make install)
- make example and example_zc

But reopen zbalance_ipc after close still error :

/home/test/PF_RING-8.8.0-stable/userland/examples# ./pfcount -i zc:103@1 pfring_open error [Resource temporarily unavailable] (pf_ring not loaded or interface zc:103@1 is down ?)

@jolysoul127 it seems be be working in our lab compiling from source code.. anyway I suggest not to mix binaries from packages with binaries compiled from source code as this may lead to unaligned code and create issues

@cardigliano i have install fresh ubuntu 22.04 but everything is the same. can you please let me know your OS, kernel, gcc version and PF_RING version which build from Git Thank you
