我正在尝试使用 boost 1-49 的序列化库编译一个 android 应用程序。具体来说，这个项目有一些方便的脚本来完成工作：https ://github.com/MysticTreeGames/Boost-for-Android
使用 gnu-libstdc++ 4.6 for armeabi-v7a，针对官方 ndk-r8 构建的 Boost 没有问题。
至少，它能够创建 libboost_serialization-gcc-mt-1_49.a 而不会遇到任何错误。在构建过程中引发了几个警告，'禁止零大小数组'_pad' [-pedantic]'，'不支持'long long'，'不允许命名可变参数宏'，似乎没有什么严重的，但我没有' t 自称是 gnu 编译器方面的专家。
构建 boost 还创建了 libboost_wserialization-gcc-mt-1_49.a，这看起来很奇怪，但可能无关紧要。我没有将它包含在我的 makefile 中。
无论如何，当我现在尝试使用这个库编译我的代码时，我会收到以下错误：

好的，我在午餐时间在这方面取得了一些进展。通过实际挖掘 boost 中的那些 src 文件，我发现 mbtowc 及其倒数是 gnu-libstdc++ 的一部分。因此，不知何故，当我构建 boost 时，它一定没有得到正确的参考。午餐时间不能再给它了，但我已经查看了 boost 是如何编译的，并且使用的标志应该适当地链接所有内容。
从构建日志：

鉴于我在库中遇到错误，并且它是我在代码中使用的唯一库，我认为 makefile 不会有问题。不过，为了彻底起见，这里有以下内容：Android.mk，包含在我保存已编译的 boost 库的位置：

我最好的猜测是我没有正确构建提升，但不能肯定地说。什么可能导致这些错误？我什至无法搜索据称在序列化库中引用的文件（“mbtowc”和排列）。它是否试图引用我没有通过 makefile 包含的系统或文件系统提升库？
