I have followed this steps: 1) create a JNI Folder and put there all the source files and the wrapper. Configuration Problem : Windows Visual Studio.
#Android ndk cannot link function android
and I get fatal error: sys/sysctl.h file not found cant figure out why. The link given in the Android Preferences for the Android NDK is incorrect and does not exist. I am not sure if the ndk-build add this symbol to the static lib.ĪPP_PLATFORM := android-21 // I change this to android-14, also not workĪPP_CPPFLAGS:=-std=c++11 -fexceptions -frtti -DANDROID -DDEBUG The linker drops any object 'files' (in your case, foo.o) from used static libraries, unless they are 'pinned' by one of the objects in the shared lib (in your case, native.o ). I am trying to add c++ native project to my library project. Foreign Function Interface aka FFI is a neat mechanism for supercharging your Dart and Flutter apps by harnessing the power of native C libraries. I can not find reference of ndk in my source code. too many undefined reference errors for OpenCV in NDK coding.
load(std::string const&) even after I link the libraries. I am using one of the libraries libboostfilesystem-clang-mt-a32-166.
#Android ndk cannot link function for android
Undefined reference to function Android NDK. I have an issue when compiling my code using Boost for Android with Android Studio ndk. : dlopen failed: cannot locate symbol "_ZNSt6_ndk17codecvtIcc9mbstate_tE2idE" referenced by "/data/app/-2/lib/x86/libtest.so".Īt (Runtime.java:372)Īt (System.java:1076)Īt .Sdk.(Sdk.kt:15)Īt .MyApplication.onCreate(MyApplication.kt:12)Īt (Instrumentation.java:1013)Īt (ActivityThread.java:4707)Īt .-wrap1(ActivityThread.java)Īt $H.handleMessage(ActivityThread.java:1405)Īt android.os.Handler.dispatchMessage(Handler.java:102)Īt android.os.Looper.loop(Looper.java:148)Īt (ActivityThread.java:5417)Īt .invoke(Native Method)Īt .ZygoteInit$n(ZygoteInit.java:726)Īt .ZygoteInit.main(ZygoteInit.java:616)Īnd I find symbol _ZNSt6_ndk17codecvtIcc9mbstate_tE2idE appears on the static library I build. Android studio 1.3 NDK cannot resolve c++ header / code. The error is E/AndroidRuntime: FATAL EXCEPTION: main
I use ndk-build to build a static library and compile to a *.so successfully, but Runtime error is thrown when runs in android simulator.
