java.lang.unsatisfiedLinkError lib not found :(failed to link mylib.so)

i've successfully cross compiled a c++ library to the android plateform using the android ndk standalone toolchain. i've created a new android application project into Eclipse with a jni dolder and Android.mk file and when i do an ndk-build the building goes well and it adds mylib.so to libs/armeabi folder The problem is when i do a System.loadLibrary("mylibname"); i get the following error in the logcat: Unable to dlopen(/data/data/com.oussama.firsttry/lib/libdash.so): Cannot load library: link_image[1995]: failed to link libdash.so that cause a java.lang.UnsatisfiedLinkError: my lib not found**.

There must be a library that my lib depends on and the emulator can't load it so i've done a readelf -d mylib.so and here is the result:

Here is my Android.mk file:

 include $(PREBUILT_SHARED_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE

 include $(PREBUILT_SHARED_LIBRARY)

 include $(CLEAR_VARS)

 LOCAL_MODULE := d LOCAL_SRC_FILES := libdash.so
 LOCAL_SHARED_LIBRARIES := c m dl 

 LOCAL_STATIC_LIBRARIES := libz libxml libcurl  include
 $(PREBUILT_SHARED_LIBRARY)

i'am really stuck now and i can't figure out what is the missing library

When i do an ndk-build V=1 -B i get the following result:

I would be thankfull if any one can help me.

You should use the system versions of libm, libc and libdl shared libraries,

LOCAL_LDLIBS := -lm -ldl 

If you can't, link them statically.
