## comparison of `pkgconf` and `pkg-config` dependency resolvers
pkgconf builds an acyclic directed dependency graph. This allows for the user
to more conservatively link their binaries -- which may be helpful in some
to more conservatively link their binaries -- which may be helpful in some
environments, such as when prelink(1) is being used. As a result of building
a directed dependency graph designed for the specific problem domain provided
by the user, more accurate dependencies can be determined. pkg-config, on the
other hand builds a database of all known pkg-config files on the system before
attempting to resolve dependencies, which is a considerably slower and less
efficient design.
by the user, more accurate dependencies can be determined.
Current release versions of pkg-config, on the other hand, build a database of all
known pkg-config files on the system before attempting to resolve dependencies, which
is a considerably slower and less efficient design. Efforts have been made recently
to improve this behaviour.
As of the 1.1 series, pkgconf also fully implements support for `Provides` rules,
while pkg-config does not. pkg-config only provides the `--print-provides` functionality
as a stub. There are other intentional implementation differences in pkgconf's dependency
resolver verses pkg-config's dependency resolver in terms of completeness and correctness,
such as, for example, how `Conflicts` rules are processed.
