我在本机应用程序中链接 STL 时遇到一些问题。map::operator[] 和 map::insert 的链接都失败，而其他 map 函数则成功。我的 Application.mk 是：
APP_STL := gnustl_static
APP_CPPFLAGS := -fexceptions -frtti
APP_CPPFLAGS += -g3
APP_CPPFLAGS += -DDEBUG
APP_ABI := armeabi-v7a
APP_PLATFORM:=android-14
NDK_TOOLCHAIN_VERSION:=4.6
本机代码包含两个文件夹级别。我为每个内部文件夹创建了一个 Android.mk 文件来编译和生成一个静态库。我在最深的文件夹中使用 std::map 。Android.mk 看起来像：
TEMP_PATH_REG := $(call my-dir)
LOCAL_PATH := $(TEMP_PATH_REG)
include $(call all-subdir-makefiles)
LOCAL_PATH := $(TEMP_PATH_REG)
include $(CLEAR_VARS)
LOCAL_MODULE := registration
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../glm/
LOCAL_SRC_FILES := registration_factory.cpp \
inertial.cpp
LOCAL_LDLIBS := -llog -landroid -lEGL
LOCAL_STATIC_LIBRARIES := android_native_app_glue
include $(BUILD_STATIC_LIBRARY)
$(call import-module,android/native_app_glue)
当我构建项目时，我收到以下错误：

我做错了什么？
非常感谢。
