hivex-1.3.13-4.fc25 fails to build in F25: Making all in ruby make[2]: Entering directory '/builddir/build/BUILD/hivex-1.3.13/ruby' rake build rake aborted! ERROR: 'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (available in RDoc 2.4.2+) instead. /builddir/build/BUILD/hivex-1.3.13/ruby/Rakefile:27:in `rescue in <top (required)>' /builddir/build/BUILD/hivex-1.3.13/ruby/Rakefile:24:in `<top (required)>' LoadError: cannot load such file -- rdoc/task /builddir/build/BUILD/hivex-1.3.13/ruby/Rakefile:25:in `<top (required)>' (See full trace by running task with --trace) Makefile:1631: recipe for target 'all' failed I don't know what causes the failure. The first failure is dated to 2016-04-09 <https://apps.fedoraproject.org/koschei/build/1558312> that was apparently not caused by ruby. There can be more reasons.
This is likely to be a missing dependency. Recently dnf in Koji in Rawhide was changed so that Recommended packages are no longer installed. Since rubygem-rdoc is not listed as an explicit BuildRequires, but was (previously) only being pulled in as a side effect of a Recommended dep of some other package, it is now missing. I've pushed a new package that adds the explicit BR, so let's see what happens: http://koji.fedoraproject.org/koji/taskinfo?taskID=13995135
And rubygem(json) too (but see also bug 1325022). http://koji.fedoraproject.org/koji/taskinfo?taskID=13995249
That seems to have worked, so closing. Thanks for the clear bug report.
