Can t include C headers like vector in Android NDK

Question

When I try to include any C   class like vector in my Android NDK project  using NDK r5b  the latest   I get an error like the following     Compile   thumb    test-libstl  lt   test-libstl cpp  Users nitrex88 Desktop Programming EclipseProjects STLTest jni test-libstl cpp 3 18  error  vector  No such file or directory  Other people who reported this issue online have claimed success by adding  APP STL    stlport static  to their Application mk file  I have done this as well as tried every other possible value for APP STL  I ve cleaned to project  ran ndk-build clean  deleted the obj and libs folders  and still when I compile it cannot find the vector class  I ve been working on this for a number of weeks now  since NDK r5 came out  and would really appreciate if someone has any advice  Thanks

This is what caused the problem in my case (CMakeLists.txt):

set (CMAKE_CXX_FLAGS "...some flags...")

It makes invisible all earlier defined include directories. After removing / refactoring this line everything works fine.

Even Sebastian had given a good answer there 3 more years ago  I still would like to share a new experience here  in case you will face same problem as me in new ndk version   I have compilation error such as   fatal error  map  No such file or directory fatal error  vector  No such file or directory   My environment is android-ndk-r9d and adt-bundle-linux-x86 64-20140702  I add Application mk file in same jni folder and insert one  and only one  line   APP STL    stlport static   But unfortunately  it doesn t solve my problem  I have to add these 3 lines into Android mk to solve it   ifndef NDK ROOT include external stlport libstlport mk endif   And I saw a good sharing from here that says   stlport shared  is preferred   So maybe it s a better solution to use stlport as a shared library instead of static  Just add the following lines into Android mk and then no need to add file Application mk   ifndef NDK ROOT include external stlport libstlport mk endif LOCAL SHARED LIBRARIES    libstlport   Hope this is helpful

I m using Android Studio and as of 19th of January 2016 this did the trick for me   This seems like something that changes every year or so   Go to  app -  Gradle Scripts -  build gradle  Module  app   Then under model       android ndk       and add a line  stl    gnustl shared   Like this   model                 android ndk           moduleName    gl2jni          cppFlags add  -Werror           ldLibs addAll   log    GLESv2            stl    gnustl shared           lt -- this is the line that I added

If you are using ndk r10c or later  simply add APP STL c   static to Application mk

It is possible  Here is some step by step   In  PROJECT DIR jni Application mk   APP STL                    stlport static   I tried using stlport shared  but no luck  Same with libstdc     In  PROJECT DIR jni Android mk   LOCAL PATH      call my-dir   include   CLEAR VARS   LOCAL MODULE       hello-jni LOCAL SRC FILES    hello-jni cpp LOCAL LDLIBS       -llog  include   BUILD SHARED LIBRARY    Nothing special here  but make sure your files are  cpp   In  PROJECT DIR jni hello-jni cpp    include  lt string h gt   include  lt jni h gt   include  lt android log h gt    include  lt iostream gt   include  lt vector gt     define  LOG TAG     hellojni   define  LOGI         android log print ANDROID LOG INFO LOG TAG   VA ARGS     define  LOGE         android log print ANDROID LOG ERROR LOG TAG   VA ARGS       ifdef   cplusplus extern  C     endif     Comments omitted      void Java com example hellojni HelloJni stringFromJNI  JNIEnv  env                                                    jobject thiz         std  vector lt std  string gt  vec          Go ahead and do some stuff with this vector of strings now      ifdef   cplusplus    endif   The only thing that bite me here was  ifdef   cplusplus   Watch the directories   To compile  use ndk-build clean  amp  amp  ndk-build

If you are using Android studio and you are still seeing the message  error  vector  No such file or directory   or other stl related errors  when you re compiling using ndk  then this might help you   In your project  open the module s build gradle file  not your project s build grade  but the one that is for your module  and add  stl  stlport shared   within the ndk element in defaultConfig   For eg   android       compileSdkVersion 21     buildToolsVersion  21 1 2       defaultConfig           applicationId  com domain app          minSdkVersion 15         targetSdkVersion 21         versionCode 1         versionName  1 0           ndk               moduleName  myModuleName              stl  stlport shared

Let me add a little to Sebastian Roth s answer   Your project can be compiled by using ndk-build in the command line after adding the code Sebastian had posted  But as for me  there were syntax errors in Eclipse  and I didn t have code completion   Note that your project must be converted to a C C   project   How to convert a C C   project  To fix this issue right-click on your project  click Properties  Choose C C   General -  Paths and Symbols and include the   ANDROID NDK  sources cxx-stl stlport stlport to Include directories  Click Yes when a dialog shows up     Before    After    Update  1  GNU C  Add directories  rebuild  There won t be any errors in C source files GNU C    Add directories  rebuild  There won t be any errors in CPP source files
