Android NDK对`std :: ios_base :: Init :: Init（）'的未定义引用

标签： c++ android-ndk cocos2d-x

我要从cocos2d-x 3.9迁移到cocos2d-x 3.17.2，并且在构建android studio项目时，在链接Wwise libAuroPannerMixer.a时出现错误。 NDK版本19.2，使用clang编译，wwise版本2017.1.3.6377。也许有人遇到同样的问题？

Application.mk 

APP_STL := c++_static

APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -std=c++11 - 
fsigned-char -Wno-extern-c-compat
APP_LDFLAGS := -latomic -stdlib=libc++ -lstdc++

APP_ABI := arm64-v8a
APP_SHORT_COMMANDS := true

ifeq ($(NDK_DEBUG),1)
  APP_CPPFLAGS += -DCOCOS2D_DEBUG=1
  APP_OPTIM := debug
else
  APP_CPPFLAGS += -DNDEBUG
  APP_OPTIM := release

2 个答案:

答案 0 :(得分：0)

我认为libAuroPannerMixer.a的构建不正确。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该库，它对我来说没有任何声音麻烦。我在wwise论坛上创建了一个主题topic。

答案 1 :(得分：0)

我至少看到了三个问题。

APP_LDFLAGS := -latomic -stdlib=libc++ -lstdc++

删除整行。第一个标志是多余的（使用ndk-build是自动的），第二个标志是错误的。

ndk-build在链接命令中的正确位置手动链接标准库，并使用-nostdlib++禁止编译器的默认行为。添加-stdlib=libc++可以解决这个问题，因此现在它被链接了两次并且在错误的位置。

-lstdc++链接了错误的库。

c:\jenkins\ws\wwise_v2017.1\wwise\sdk\source\build\android\android-21_arm64-v8a\include\c++\4.9.x/iostream:74: undefined reference to `std::ios_base::Init::Init()'

在此处特别注意std命名空间的路径和名称。 include\c++\4.9.x是gnustl标头的路径，而std是gnustl名称空间的名称。 libc ++使用不同的标头路径，名称空间为std::__ndk1（第二部分是内联名称空间，因此您无需担心编码时的实现细节，但它会在构建时中断，以保护您这些问题）。您的wwise库是使用gnustl构建的，并且您正在使用libc ++。这两个库不兼容，不能在同一应用程序中使用。

您需要使用libc ++重建wwise才能将其与libc ++一起使用。如果无法执行此操作，则需要还原到NDK r17（支持gnustl的最新版本）。请注意，这样一来，您还将失去对C ++ 14和C ++ 11的访问权限（以及重新引入此后修复的所有错误），因此，强烈建议您重建wwise而不是使用旧的NDK。
