[Oisf-users] Suricata 3.0 issues on Debian 7 with PFRING / libcap-ng-dev

[David Touzeau]

Hi i'm trying to compile suricata with pf_ring.

the main issue ( i did not know if it is a debian bug ) is that the 
library libcap-ng cannot be detected with the following error

checking for cap-ng.h... yes
checking for capng_clear in -lcap-ng... no

    WARNING!  libcap-ng library not found, go get it
    from http://people.redhat.com/sgrubb/libcap-ng/
    or your distribution:

    Ubuntu: apt-get install libcap-ng-dev
    Fedora: yum install libcap-ng-devel

    Suricata will be built without support for dropping privs.


It appears ld is on error :

ld -lcap-ng --verbose

../..

The same error result on libpnsr4

Is there a way to fix it ??
