我一直在尝试编译包含 OpenCV 库的共享库。我的示例 android make 文件如下：
LOCAL_PATH := (call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libopencvXXX
LOCAL_SRC_FILES := libs/opencv/libopencvXXX.a
include $(PREBUILT_STATIC_LIBRARY)
OPENCV_LIB_TYPE := STATIC
OPENCV_INSTALL_MODULES := on
OPENCV_CAMERA_MODULES := on
LOCAL_MODULE := libXXX
LOCAL_CPPFLAGS := -std=c++11 -fexceptions
LOCAL_CPP_FEATURES += exceptions
LOCAL_CFLAGS := -std=gnu++11 -fexceptions
LOCAL_LDLIBS := -llog -ldl
LOCAL_SRC_FILES := XXX.cpp
LOCAL_C_INCLUDES := <path to opencv header files>
LOCAL_STATIC_LIBRARIES := stdc++
LOCAL_STATIC_LIBRARIES += libopencvXXX
include $(BUILD_SHARED_LIBRARY)
但是，它不断抛出以下错误：
[INFO] jni/libs/opencv/libopencv_core.a(persistence.cpp.o):persistence.cpp:function icvGets(CvFileStorage*, char*, int): error: undefined reference to 'gzgets'
[INFO] jni/libs/opencv/libopencv_core.a(persistence.cpp.o):persistence.cpp:function icvXMLSkipSpaces(CvFileStorage*, char*, int): error: undefined reference to 'gzeof'
我尝试了如下几个选项。
LOCAL_LDLIBS += -lz
LOCAL_LDLIBS += -L<NDK root>/platforms/android-19/arch-arm/usr/lib -lz
但没有任何帮助。有人知道我该如何解决这个问题吗？
编辑：忘记添加，当我添加包括'-lz'在内的上述两个选项时，它会抛出一个错误，提示“未找到本机编译库，本机编译是否成功完成！”。
