Hi all, I wanted to package ksniff aka kubectl-sniff (https://github.com/eldadru/ksniff) for openSUSE. It allows sniffing the network traffic inside a Kubernetes pod and forwards it to a local wireshark instance. Very helpful sometimes. Anyways, to work properly it needs a "static tcpdump binary" that it can inject into the pod. I wanted to build it inside the knsiff package. But as soon as I add the "CFLAGS=-static" from the ksniff makefile, the configure breaks as the compiler cannot create executables.

https://build.opensuse.org/package/show/home:ojkastl_buildservice:Branch_dev...

Here is the interesting Makefile part:

https://github.com/eldadru/ksniff/blob/master/Makefile#L42

"CFLAGS=-static ./configure --without-crypto && make" I added all of the %configure macro options manually and tried to add BuildRequires, but I am stuck. Which package do I have to add to get this working? Thanks in advance! Kind Regards, Johannes
