Use as Library

NOTE: Although the core/iptables is primarily a package of binaries; it also can be treated as a library of headers. Library packages can be set as runtime or build time dependencies, however they are typically used as buildtime dependencies. See Defining your dependencies for more information.

Viewing library files

To view the library files first get the habitat installation directory

hab pkg path core/iptables
/hab/pkgs/core/iptables/1.8.4/20200921113838

Then list the libraries, for example:

ls -1 $(hab pkg path core/iptables)/lib
