SDL2サンプルビルドエラーがandroid ndk r14

Question

私のubuntu 16.04マシンのSDL2ソース（2.0.5）でサンプルをビルドするためにテストしました。

https://wiki.libsdl.org/Androidによれば、私はアンドロイドのsdkとndk r14をインストールし、自分の環境変数を設定しました。

しかし、「シンプルビルド」の章で次のコマンドを使用してビルドできませんでした。

cd /usr/src/SDL2/build-scripts/ 
./androidbuild.sh org.libsdl.testgles ../test/testgles.c 

以下のエラーが発生します。

Error: The project either has no target set or the target is invalid. 
Please provide a --target to the 'android update' command.

「アンドロイドアップデート」についての最初のエラーは、プロジェクトディレクトリ内の手作業で更新コマンドを実行することで修正できると思います。

しかし、LLVMバックエンドがSDL_wave.c

をコンパイルするには、このエラーになりますなぜ私が推測することはできませんがSDL2はまだクラン3.8でビルドするためにサポートしていませんか？

Answer 1

私はちょうど同じ問題を抱えていますが、私はそれを解決します、それはとても良い感じです！

私はそれがコンパイラclang.exeによって引き起こされたと思います。

あなたがしなければならないのは、（あなたがNDK_BUILDを使用している場合）あなたのapplication.mkを編集している

にビットを追加するには1行「NDK_TOOLCHAIN_VERSION = 4.9（あなたにGCCのバージョンに依存）」

Answer 2

を追加L.wcの答えはこれを試してみてください。

NDK_TOOLCHAIN_VERSION =あなたのNDKのインストールでツールチェインの4.9 ./androidbuild.sh org.libsdl.testgles ../test/testgles.c

4.9になりますバージョン。
