Undefined reference to a a lot of caffe2 libries

Question

I experience the same error as has been described here: Android NDK make. Hundreds of "undefined reference error"s

However, after we use the solution we get another type of error:

We have built caffe2 from source and updated our application's CMakeLists.txt as follows:

cmake_minimum_required(VERSION 3.4.1)

add_library(
             native-lib
             SHARED
             src/main/cpp/native-lib.cpp
             )
find_library(
          android-lib
          android
          )

include(AndroidNdkModules)
android_ndk_import_module_cpufeatures()

add_library(
    caffe2
    STATIC
    IMPORTED
    )
set_target_properties(
    caffe2
    PROPERTIES IMPORTED_LOCATION
    ${CMAKE_CURRENT_LIST_DIR}/src/main/jniLibs/${ANDROID_ABI}/libcaffe2.a
    )
add_library(

    )
set_target_properties(
    thread_pool
    PROPERTIES IMPORTED_LOCATION

    )
add_library(

    )
set_target_properties(
    clog

    ${CMAKE_CURRENT_LIST_DIR}/src/main/jniLibs/${ANDROID_ABI}/libclog.a
    )

add_library(

find_library(

     log
     )

target_link_libraries(

                       -Wl,--no-whole-archive
                       NNPACK
                       thread_pool
                       clog
                       protobuf
                       cpufeatures
                       ${log-lib}
                       ${android-lib})

It seems that the `caffe2` imported target is missing its libc++ dependencies. You probably need to use `set_target_properties` to set [`IMPORTED_LINK_DEPENDENT_LIBRARIES`](https://cmake.org/cmake/help/latest/prop_tgt/IMPORTED_LINK_DEPENDENT_LIBRARIES.html) to that location. — compor, Sep 05 '18 at 13:05
We are using android studio. Could you clarify what command we should use and what we should link? — Augustinas Makevičius, Sep 05 '18 at 13:20
I assumed you wrote that `CMakeLists.txt`; you should use `set_target_properties(caffe2 PROPERTIES IMPORTED_LINK_DEPENDENT_LIBRARIES [path to libc++.so or .a]`. Basically the path to the built `/home/augustinas/Android/Sdk/ndk-bundle/sources/cxx-stl/llvm-libc++/` library, wherever that is placed. — compor, Sep 05 '18 at 13:35
Nope. Error still here. Do you have any more advice? Full output: https://pastebin.com/7iRgkVgS — Augustinas Makevičius, Sep 05 '18 at 14:13
You still seem to be mixing `libgnustl_shared.so` with `libc++_static.a`. Some of your static libraries are built with either one or the other, that's why that link step fails. I cannot see this option `-DANDROID_STL=gnustl_shared` (suggested by [that](https://stackoverflow.com/a/51945444/3048763) post) anywhere on the CMake invocation; did you clean your CMake cache? — compor, Sep 05 '18 at 14:37
-DANDROID_STL=gnustl_shared is used in another place. It is supplied 100% — Augustinas Makevičius, Sep 05 '18 at 14:42
I cannot see it the first 2 lines in your pastebin link where `Error while executing process...cmake with arguments...` etc — compor, Sep 05 '18 at 14:47
Let us [continue this discussion in chat](https://chat.stackoverflow.com/rooms/179482/discussion-between-augustinas-makevicius-and-compor). — Augustinas Makevičius, Sep 05 '18 at 14:54
Please read [Under what circumstances may I add “urgent” or other similar phrases to my question, in order to obtain faster answers?](//meta.stackoverflow.com/q/326569) - the summary is that this is not an ideal way to address volunteers, and is probably counterproductive to obtaining answers. Please refrain from adding this to your questions. — halfer, Sep 05 '18 at 21:13
