【ビルドエラー】GoogleAnalyticsとAdMobを両方実装しようとするとビルドエラーが発生する件

かつてGoogleAnalyticsとAdMobを両方実装しようとしたのですが、
Link Errorのため断念したことがありました。

今回、GoogleAnalyticsと別のSDKを実装しようとしたところ、
同様っぽいエラーが発生しました。

こんな感じの。長いですがそのまま貼ります。

再度、解決法を調査したところ、
こちらが見つかりました。

http://stackoverflow.com/questions/22832200/google-analytics-sdk-3-0-sqlite3-linker-errors-in-ios

要約すると、Linked Frameworks and Librariesに
libsqlite3.0dylibを追加すれば良いようです。

で、やってみたところ、
無事ビルドできました！！

今回は表題の2SDKと全く同じではないのですが、
恐らく解決法も同じかと思われます。

後ほど試してみる予定です。

しかし、こういうのは本当に日本語のドキュメントないですね。
気合で英語を読まないと詰みそうです。

プログラマは英語必須だなぁ。
