yosemite上のGentoo/Prefixでsys-apps/dbusのemergeがコケる
OSX 10.10.2な環境でsys-apps/dbusをemergeするとconfigure phaseでコケる。
configure: error: launchd support explicitly enabled but not available
こんな感じのエラーログが出る。
原因はlaunch.h内でインクルードしているxpc/base.hでclangでしか使えないプリプロセッサディレクティブ(__has_extension(),__has_feature())を使っているため。
要するにコンパイラをgccからclangに代えてやればコンパイルは通るので、
% CC=clang CXX=clang++ emerge sys-apps/dbus
してやればコンパイル出来る。
次回以降もclangを指定してやらないとコンパイルが失敗するため、
% echo -e "CC=clang\nCXX=clang++" >> ${prefix_root}/etc/portage/env/clang
% echo -e "sys-apps/dbus clang" >> ${prefix_root}/etc/portage/package.env(もちろん適宜変更してください)
すると次回以降もclangでコンパイルされる(はず)。
参考:Clang - Gentoo Wiki
これはバグレポート案件なのだろうか。
英語が出来ないのでバグレポート書いてないんですが誰か暇な人いたら書いてくれませんか。
早くGentoo/Prefixでemerge mikutterしたい。
