引き継いだプロジェクトで使用されているAndroid::MutexとAndroid::AudioTrackのリンク時に、奇妙な未定義の参照が発生します。

誰かアイデアはありますか？含めるAndroid静的ライブラリはありませんか？

これも私を悩ませました-しかし、私は最終的にBionicのヘッダー（bionic/libc/include）とリンクすることによってそれを解決しました-そして-重要な部分#define-'ing HAVE_PTHREADS（すなわちadd LOCAL_CFLAGS += HAVE_PTHREADS）。

さて、これらはいくつかの奇妙なエラーです... android::Mutexまたはandroid::AudioTrackライブラリから何かを参照するたびに、リンカーはそれらの関数を見つけることができないようです。私が言えるのは、これらのライブラリはandroid標準ライブラリの一部ではないため、ビルドパスにそれらがあることを確認してください。そうでない場合は幸運を祈ります。
