MacPorts を使用して、GCC 4.7.2 のユニバーサル ビルドをセットアップしています。その依存関係の 1 つは、libstdcxxビルドしてから削除する というサブポートです。
再構築後にスタティック ライブラリが削除されないように、portfileのlibstdcxxエントリを編集しました。gcc47libstdc++.a
ただし、スタティック ライブラリは 64 ビット ( x86_64) ファイルです。
$ sudo port -n upgrade --force libstdcxx +universal
---> Computing dependencies for libstdcxx
...
$ lipo -info /opt/local/lib/libstdc++.a
input file /opt/local/lib/libstdc++.a is not a fat file
Non-fat file: /opt/local/lib/libstdc++.a is architecture: x86_64
i386また、このファイルにアーキテクチャのサポートを追加したいと思います。
ファットな静的libstdc++ライブラリを構築するには、どのような追加手順に従う必要がありますか? または、これは MacPorts では不可能ですか? GCC 4.7.2 全体を 2 回 (両方i386とx86_64アーキテクチャのサポートを取得するために) 再配布してコンパイルし、アプリケーションのソースと共に、この 1 つの静的ライブラリにリンクするための唯一の他のオプションはありますか?

Brett Hale の提案はうまくいかなかったようです。ビルド プロセスが失敗しました。エラー ログのスニペットを次に示します。
