rpmbuild-order alternatives and similar packages

Based on the "Distribution" category

Do you think we are missing an alternative of rpmbuild-order or a related project?

Add another 'Distribution' Package


Build Status Hackage license


This package originally based on code from cabal-sort, sorts rpm package spec files by build order.

$ rpmbuild-order --help
$ rpmbuild-order sort mycore mylib myapp
mylib mycore myapp

The arguments passed can either be directories containing the package, or spec files.

If the dependency graph has cycles then an error will be output with a list of cycles and any subcycles.

Using the rpmbuild-order deps and rdeps commands the ordered dependencies and reverse dependencies of a package can be obtained from the current set of checked out package sources.


As of version 0.4, a library is also provided.

There are two modules:

  • Distribution.RPM.Build.Graph provides lower level functions for generating RPM dependency graphs
  • Distribution.RPM.Build.Order provides higher level functions for sorting packages in build dependency orders and output.

Please see the documentation for more details.

Notes and known problems

  1. Given packages A, B, C, where C depends on B, and B depends on A, and you call

    rpmbuild-order sort C.spec A.spec

then the output may be wrong if C does not have a direct dependency on A. Even if the order is correct, B is missing in the output and thus in this case the list of packages cannot be reliably used for a sequence of builds.

However the deps and rdeps commands take other neighbouring package directories into account.

  1. repoquery is not used to resolve meta-dependencies or files to packages. So if a package BuildRequires a file, it will not be resolved to a package. This may get addressed some day, but file dependencies seem less common for BuildRequires than Requires.

  2. rpmspec is used to parse spec files (for macro expansion etc): so missing macros packages can lead to erroneous results in some cases.
