std::map

[alex alex]

Hi
I have a problem : when i add std::map in application it compiles fine
but in logcat i get signal 4 <SIGILL> code 1 <ILL_ILLOPC> , fault adr
83bd8804. I created a test application that works. When i add

map<char,int> first;

first['a']=10;

it compiles fine but i get the same thing in logcat . I'm using the
external dependencies form $(ANDROID_NDK_ROOT)/sources/cxx-stl/stlport/
stlport and the libraries $(ANDROID_NDK_ROOT)/cxx-stl/stlport/libs/
armeabi/libstlport_static.a and $(ANDROID_NDK_ROOT)/sources/cxx-stl/
gnu-libstdc++/libs/armeabi/libstdc++.a
from ndk r5c for a android 2.3 application

Can you help please!

You can't mix and match C++ STL implementations. Select one and stick to it.

i tried it just with
$(ANDROID_NDK_ROOT)/sources/cxx-stl/stlport/libs/armeabi/libstlport_static.a
and it's still not working it only works if i comment the second line :

       map<char,int> first;

      // first['a']=10;

How do you build your code exactly? Are you using ndk-build and an Android.mk or not?

[alex alex]

I'm using ndk r5c, visual studio 2010 and ant build . I'm not using Android.mk.

vs2010 has probably nothing to do with it.

How are you invoking the compiler? Did you try building a standalone toolchain (see docs/STANDALONE-TOOLCHAIN.html)

A standalone toolchain is probably the only sane way to generate machine code for Android if you're not using the NDK build system.

And it only supports GNU libstdc++, not stlport, btw.

I am using ndk build systems the only things i'm not using are cygwin and Android.mk .In stead of Android.mk i'm using MsBuild .

And i am wondering is anybody made an application that uses std::map (and of course if ti works ).

You are probably trying to call the toolchain binaries directly from MsBuild, this cannot work, really, unless you setup a standalone toolchain installation.

Read docs/STANDALONE-TOOLCHAIN.html for more information.

Hi again
I compiled the sample san-angeles form $(ANDROID_NDK_ROOT)\samples and it worked fine on emulator and on my phone.
Then i added #include <map> form $(ANDROID_NDK_ROOT)\sources\cxx-stl\stlport\stlport and in the function  i added :



void
Java_com_example_SanAngeles_DemoRenderer_nativeInit( JNIEnv*  env )
{
   int importGLInit();
    appInit();
    gAppAlive    = 1;
    sDemoStopped = 0;
    sTimeOffsetInit = 0;
   
    //vector<int> first; (3,0);
   
    std::map<char,int> first;

    first['a']=10;

}

it compiles and it instals  on emulator and phone but at runtime siganl 4 SIGILL   ILL_ILLOPC .
It only works if i comment this :

   //first['a']=10

BTW vector works .Hope you can help me.
