Android NDK 未定义对 `std::ios_base::Init::Init()' 的引用
Android NDK undefined reference to `std::ios_base::Init::Init()'
我正在从 cocos2d-x 3.9 迁移到 cocos2d-x 3.17.2，当我构建 android studio 项目时，链接 Wwise libAuroPannerMixer.a 时出现错误。 NDK 版本 19.2，用 clang 编译，wwise 版本 2017.1.3.6377。也许有人有同样的问题？

我认为 libAuroPannerMixer.a 构建不正确。在接下来的 wwise 版本中没有 Auro 库。结果，我只是从项目中删除了那个库，它对我有用，没有任何声音问题。我在 wwise 论坛上创建了一个主题 topic。
我至少看到三个问题。
APP_LDFLAGS := -latomic -stdlib=libc++ -lstdc++
删除整行。第一个标志是多余的（ndk-build 是自动的），后两个是错误的。
ndk-build 手动 link 将标准库放在 link 命令的正确位置，并使用 -nostdlib++ 来禁止编译器的默认行为。添加 -stdlib=libc++ 会破坏它，所以现在它被 link 编辑了两次，而且在错误的位置。
-lstdc++ link 库错误。
c:\jenkins\ws\wwise_v2017.1\wwise\sdk\source\build\android\android-21_arm64-v8a\include\c++.9.x/iostream:74: undefined reference to `std::ios_base::Init::Init()'
请特别注意此处 std 命名空间的路径和名称。 include\c++.9.x 是 gnustl header 的路径，std 是 gnustl 命名空间的名称。 libc++ 使用不同的 header 路径，命名空间为 std::__ndk1（第二部分是内联命名空间，因此这是一个实现细节，您在编码时无需担心，但它在构建时中断以保护您免受这些问题的影响）。您的 wwise 库是使用 gnustl 构建的，而您使用的是 libc++。这两个库不兼容，不能在同一个应用程序中使用。
您需要使用 libc++ 重建 wwise 才能将其与 libc++ 一起使用。如果您无法这样做，则需要恢复到 NDK r17（支持 gnustl 的最后一个版本）。请注意，如果这样做，您也会失去对 C++14 和 C++11 的某些部分的访问权限（以及重新引入我们从那时起修复的任何错误），因此强烈建议重建 wwise 而不是使用一个旧的 NDK。
我正在从 cocos2d-x 3.9 迁移到 cocos2d-x 3.17.2，当我构建 android studio 项目时，链接 Wwise libAuroPannerMixer.a 时出现错误。 NDK 版本 19.2，用 clang 编译，wwise 版本 2017.1.3.6377。也许有人有同样的问题？

我认为 libAuroPannerMixer.a 构建不正确。在接下来的 wwise 版本中没有 Auro 库。结果，我只是从项目中删除了那个库，它对我有用，没有任何声音问题。我在 wwise 论坛上创建了一个主题 topic。
我至少看到三个问题。
APP_LDFLAGS := -latomic -stdlib=libc++ -lstdc++
删除整行。第一个标志是多余的（ndk-build 是自动的），后两个是错误的。
ndk-build 手动 link 将标准库放在 link 命令的正确位置，并使用 -nostdlib++ 来禁止编译器的默认行为。添加 -stdlib=libc++ 会破坏它，所以现在它被 link 编辑了两次，而且在错误的位置。
-lstdc++ link 库错误。

请特别注意此处 std 命名空间的路径和名称。 include\c++.9.x 是 gnustl header 的路径，std 是 gnustl 命名空间的名称。 libc++ 使用不同的 header 路径，命名空间为 std::__ndk1（第二部分是内联命名空间，因此这是一个实现细节，您在编码时无需担心，但它在构建时中断以保护您免受这些问题的影响）。您的 wwise 库是使用 gnustl 构建的，而您使用的是 libc++。这两个库不兼容，不能在同一个应用程序中使用。
您需要使用 libc++ 重建 wwise 才能将其与 libc++ 一起使用。如果您无法这样做，则需要恢复到 NDK r17（支持 gnustl 的最后一个版本）。请注意，如果这样做，您也会失去对 C++14 和 C++11 的某些部分的访问权限（以及重新引入我们从那时起修复的任何错误），因此强烈建议重建 wwise 而不是使用一个旧的 NDK。
