Portsあれこれ

依存関係のエラーの対処方法

たまに依存関係系のエラーが発生し、コンパイルに行く前に終了することがある。そんな時は/usr/ports/UPDATINGを見れば殆ど解決する。

例えばこんなエラーが出たとする。

===>>> Gathering dependency list for devel/llvm40 from ports

===>>> The dependency for devel/cmake
       seems to be handled by cmake-modules-3.8.2


===>>> The devel/cmake-modules port has been deleted: Deleted, merged into devel/cmake
===>>> Aborting update

===>>> Update for llvm40-4.0.1_1 failed
===>>> Aborting update

devel/cmake-modulesが削除されdevel/cmakeに統合されたと言っている。すかさず/usr/ports/UPDATINGを見てみると…

20170914:
  AFFECTS: users of CMake & CMake Modules
  AUTHOR: adridg@FreeBSD.org

  The devel/cmake-modules port has been merged into devel/cmake.

  The benefit of being able to update the modules without the binary
  is outweighed by the issues caused by having the binary out-of-sync
  with the modules.

  Users should delete the devel/cmake-modules package and then
  upgrade or reinstall devel/cmake.

  All ports have been updated to depend only on CMake.

丁寧な解説と対処方法がちゃんと載ってるんすな。というわけで、解説通りにdevel/cmake-modulesを消してdevel/cmakeを入れてみる。

$ sudo pkg remove devel/cmake-modules
