fftw3やsndfileなどのサードパーティライブラリをXcode3.2のiPhoneプロジェクトにリンクしようとしています。プロジェクトビルド構成で「ヘッダー検索パス」を「/usr/ local / include」に設定し、「その他のリンカーフラグ」を「-lfftw3-lsndfile」に設定することで、通常のMacプロジェクトで機能するようになりました。ただし、同じ設定を使用してiPhoneプロジェクトでビルドしようとすると、「-lfftw3のライブラリが見つかりません」という終了コード1のエラーメッセージが表示されました。
AppleはiPhoneでこれを許可していませんか？これを回避する方法はありますか？

fftw3 を含むディレクトリからこのスクリプトを実行します。必要なファイルは ios-library フォルダーにあるはずです。
ライブラリをユニバーサル スタティック ライブラリとしてビルドする必要があります。図書館によって手続きは異なりますが、だいたいこんな感じです。
多くのライブラリにはさまざまなビルド手順があるため、通常、ステップ 1 が最も厄介です。これは通常、システム全体のコンパイラの代わりに iphone sdk を使用するように適切なコンパイラ フラグを設定することによって行われます。
Mac OS X 10.9.2、iOS 7.1、fftw-3.3.4 用に Nickun のスクリプトを修正しました。また、ファット ファイルに arm64 スライスを追加します。ここにスクリプトがあります - >

Appleがライブラリを許可していないわけではなく、リンク先のバージョンがx86であるため、iPhoneでは実行されません。iPhone SDKを使用してライブラリを構築してから、そのバージョンにリンクする必要があります。
または、少しやんちゃになって、メインプロジェクトにサードパーティのソースを含めることもできます。いたずらですが、Appleがあなたを止めていないことを証明し、ライブラリが電話で正常に動作するかどうかを示します。
ただし、コードを個別にビルドされたライブラリプロジェクトに保持する方がクリーンです。
fftw-3.3.8、iOS SDK 12.2、XCode 10.2で動作する 10mitri の回答に基づいています。

Adam Freeman のスクリプトを試してみましたが、これは素晴らしいものでしたが、それを機能させるには次のことを行う必要がありました。その結果を共有するためにここにいます。私の目標は、arm ベースの fftw lib を作成して、arm アーキテクチャを使用して Xcode を介して it++ lib を構築できるようにすることです。
私はloretoparisiによって投稿された問題にも遭遇します
/libbench2/libbench2.a:5:255: warning: null character ignored [-Wnull-character]
./libbench2/libbench2.a:4:8: error: source file is not valid UTF-8
回避策は、"tests"、"tools" フォルダ、および Makefile.in と Makefile.am 内の fftw-"wisdom" 関連の make ルールを削除することです。これら 2 つのフォルダのファイルがどれほど重要かはわかりません。 、しかし、UTF-8エラーなしでfftwビルドが成功できるように、それらを削除する必要がありました
スクリプトも変更する必要があります (ネオンとフロートの精度フラグを目覚めさせましたが、これらのフラグの重要性もわかりません)
