link error(glib) of gstreamer in android

[jojo]

Hi, 
My environment is following:
SDK: 4.1.2 (API 16)
NDK: android-ndk-r8e

My application is built on glib, and i use gstreamer or gstreamer-sdk to link/compile some glib code.

I directly reference some static libraries of glib like following instructions(some include path is not listed):

GSTREAMER_SDK_ROOT_ANDROID := /opt/gstreamer-sdk-android-arm-release-2013.6
or
GSTREAMER_SDK_ROOT_ANDROID := /opt/gstreamer-1.0-android-arm-1.0.7-release

app_objs := $(GSTREAMER_SDK_ROOT_ANDROID)/lib/libintl.a \
$(GSTREAMER_SDK_ROOT_ANDROID)/lib/libgio-2.0.a \
$(GSTREAMER_SDK_ROOT_ANDROID)/lib/libgobject-2.0.a \
$(GSTREAMER_SDK_ROOT_ANDROID)/lib/libgthread-2.0.a \ 
        $(GSTREAMER_SDK_ROOT_ANDROID)/lib/libgmodule-2.0.a \
$(GSTREAMER_SDK_ROOT_ANDROID)/lib/libglib-2.0.a \
$(GSTREAMER_SDK_ROOT_ANDROID)/lib/libiconv.a \

the error is report by following (should be pthread issue):
