Linker Error in STL

[vijayasarathy m]

Hi All,

I am trying to build ffmpeg with libstagefright enabled for android.

I am able to build ffmpeg libraries separately.

But when I was trying to link the ffmpeg libraries with my Android NDK, I am getting below linker errors.

 error: undefined reference to 'std::_Rb_tree_decrement(std::_Rb_tree_node_base const*)'

 error: undefined reference to 'std::_Rb_tree_insert_and_rebalance(bool, std::_Rb_tree_node_base*, std::_Rb_tree_node_base*, std::_Rb_tree_node_base&)'

 error: undefined reference to 'std::_Rb_tree_decrement(std::_Rb_tree_node_base const*)'

 error: undefined reference to 'std::_Rb_tree_insert_and_rebalance(bool, std::_Rb_tree_node_base*, std::_Rb_tree_node_base*, std::_Rb_tree_node_base&)'

 error: undefined reference to 'std::_Rb_tree_increment(std::_Rb_tree_node_base const*)'

 error: undefined reference to 'std::_Rb_tree_decrement(std::_Rb_tree_node_base*)'

All the errors are in stl_tree.h

In Application.mk, I have tried using both stlport_static and gnustl_static

I am using Android NDK r8e (android-ndk-r8e)

Please let me know how to resolve this Linker errors.

Thanks & Regards,

Well, which headers did you point your compiler to when you built
ffmpeg? The implementation of the std libraries is free to differ (as
you can see, the undefined symbols are using reserved names), as long as
the external C++ interface is compatible.

When you build ffmpeg, you'll need to point the compiler to the headers
for the std library you wish to link to.

Thanks Ben,

Actually I have linked with gnustl_shared in ffmpeg and trying to link gnustl_static in NDK.

Now I have changed gnustl_static to gnustl_shared in Application.mk

NDK is built successfully.

But When running the application, I am getting unsatisfied link error.

E/AndroidRuntime( 5424): Caused by: java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1936]:   129 could not load needed library 'libgnustl_shared.so' for 'libnative-ffplayer.so' (load_library[1091]: Library 'libgnustl_shared.so' not found)

I am even loading the library explicitly. Still facing same Runtime exception.

System.loadLibrary("gnustl_shared.so");

Any idea what I am doing wrong here.

Thanks & Regards,

This should be:

  System.loadLibrary("gnustl_shared");

Otherwise the library won't be found.

Hi All, 

I am using ndk to build my cpp files and I am also facing the issue related to RB Tree

Error:

error: undefined reference to 'std::_Rb_tree_increment(std::_Rb_tree_node_base*)'

error: undefined reference to 'std::_Rb_tree_insert_and_rebalance(bool, std::_Rb_tree_node_base*, std::_Rb_tree_node_base*, std::_Rb_tree_node_base&)'

After a long R&D also I am not able to remove this error can any one help me on this, I am also presenting my Application.mk file here

Am I missing something to include in Android.mk file, Appreciate the help.

You should not use gcc 4.6; use NDK_TOOLCHAIN_VERSION=4.8 or NDK_TOOLCHAIN_VERSION=clang in your Application.mk
