Android NDK linker Error:error: undefined reference to std::basic_string

Question

我目前正在尝试构建一些需要 boost 的源 C++ 文件的静态库。我一直在关注 hello-libs 示例并成功链接了 boost 静态文件依赖项，正如示例 example.Now 中所做的那样，在构建模块期间我得到了这些错误：

Error:error: undefined reference to 'std::basic_string, std::allocator >::basic_string(char const*, std::allocator const&)'

Error:Execution failed for task ':dummy:linkDummyArmeabiDebugSharedLibrary'.

A build operation failed. Linker failed while linking libdummy.so. See the complete log at: file:///home/cran-cg/Downloads/Hello-libs-boost/name/build/tmp/linkDummyArmeabiDebugSharedLibrary/output.txt

我一直在尝试解决这个问题，并且在 Whosebug 本身上找到了许多解决方案，建议我应该修改我的链接器路径并包含 libc++.so 库

ndk{
        moduleName = 'p2psp'
        stl = "c++_shared"
       // ldLibs.addAll('-L'+ file("/home/cran-cg/Android/Sdk/ndk-bundle/sources/cxx-stl/llvm-libc++/libs/armeabi").absolutePath)
        ldLibs.addAll(['android', 'log','atomic'])/*"${NDK_ROOT}/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi",'gnustl_static'*/
        toolchain = "clang"
        cppFlags.add("-std=c++11")
        cppFlags.add('-frtti')
        cppFlags.add('-fexceptions')
        cppFlags.addAll('-I' + file("/home/cran-cg/Android/Sdk/ndk-bundle/sources/cxx-stl/llvm-libc++/libcxx/include").absolutePath ,'-DANDROID', ' -DANDROID_NDK', '-DAWS_CUSTOM_MEMORY_MANAGEMENT', '-fPIC', '-fexceptions')
        //cppFlags.add("-I${lib_distribution_root}/boost/include".toString())
        //cppFlags.add("-I${file("src/main/jni/inc")}".toString())

        abiFilters.addAll(['armeabi'])//, 'armeabi-v7a', 'x86'])
    }

而且我对应该做什么感到困惑。请建议我如何解决此问题。谢谢:))

看起来你的 boost 库是针对 gnustl（或者可能是 stlport）构建的，而你使用的是 libc++。您不能混合和匹配 STL，因为它们不兼容 ABI。

如果您将 stl = "c++_shared" 替换为 stl = "gnustl_shared"（或者 stlport_shared，那么它应该 link。或者针对 c++_shared.[=14= 建立提升]
