--target = i386-apple-ios（iOSシミュレータ）

Question

私は、rlib（rust-opensslに依存する）とbin（rlibに依存する）を含むマルチモジュールプロジェクトを持っています。 。

それは私が一人でrlibを構築する際にokですが、私はビンを構築する際に失敗した、私はエラーを得た：

demo project to reproduce the error

Answer 1

2つの問題があります。

1. 記号（複数可）した後、正常にビルドのi386-リンゴ-IOSを、https://github.com/chshawkn/openssl-buildからhttps://github.com/x2on/OpenSSL-for-iPhoneにopensslの静的libが置き換え対象i386アーキテクチャ が見つかりません。

2. ル（/Users/user/project/target/i386-apple-ios/debug/deps/libopenssl_sys-9f3b06cb5b388503.rlib(wp-mmx.oは））OSX用に構築されました。 〜/ .cargo/bin/ccにスクリプトを入れてこれを修正してください。
