将 libmpich 链接到 android NDK

问：

我使用 buildroot 生成了 Uclib，并用它来为 ARM 设备编译 mpich。然后我创建了 Android 项目并将 libmpich.a 和 Include 文件夹复制到项目中，这是 Android.mk：

LOCAL_PATH := $(call my-dir)
# static library info

LOCAL_MODULE_FILENAME:= libmpich
LOCAL_MODULE := libmpich
LOCAL_SRC_FILES := ../prebuilt/libmpich.a 
LOCAL_EXPORT_C_INCLUDES := ../prebuilt/include
LOCAL_STATIC_LIBRARIES := libmpich
include $(PREBUILT_STATIC_LIBRARY)

# wrapper info
include $(CLEAR_VARS)

LOCAL_C_INCLUDES += ../prebuilt/include
LOCAL_MODULE    := ndk1
LOCAL_SRC_FILES := native.c
LOCAL_STATIC_LIBRARIES := libmpich
include $(BUILD_SHARED_LIBRARY)

在ndk-build之后，我收到以下错误

我不明白为什么它没有正确链接以及缺少什么

更新： 当我将 libmpl.a 添加到项目中时，所有 MPL 错误都消失了
