Using the STL with Android NDK C++

Question

I am trying to use the STL in an Android NDK C++ File. I try to use map, vector and various other stl classes and I cannot compile it because it doesn't find the files.

My classes header starts with:

#pragma once
#include <map>
#include <iostream>
#include <stdexcept>
#include <vector>
#include <set>
#include <list>
#include <algorithm>

and I get following error messages:

2>  In file included from jni/../../Classes/Assist/Test.cpp:1:
2>  jni/../../Classes/Assist/Test.h:2:15: error: map: No such file or directory
2>  jni/../../Classes/Assist/Test.h:3:20: error: iostream: No such file or directory

I read various posts and tried "APP_STL := stlport_static" and "APP_STL := gnustl_static" in an application.mk file but it didn't work.

Does anyone know how I can get this to work ?

Answer 1

I had the same problem, and then realized that I need to put: APP_STL := stlport_static

in Application.mk, not Android.mk ... doh

Then I needed to add: ${ANDROID_NDK_ROOT}\\sources\\cxx-stl\\stlport\\stlport

to the include paths in eclipse to make it not complain in the UI about errors

Answer 2

It seems that the mistake was a somehow broken NDK. I reinstalled it (delete, unzip) and now it works.
