我目前面临的问题与此问题中提出的问题相同，只是我使用的是 2.4 版本而不是 2.3.1。
我已将本机活动（从 ndk 示例）转换为 c++ 并修改了 android.mk 和 application.mk。
我有同样的错误（有 ~Mat 等等）。
当我阅读问题的答案时，我意识到我需要添加OPENCV_INSTALL_MODULES:=on and OPENCV_LIB_TYPE:=STATIC（这很奇怪，因为我有另一个使用本机 openCV 的项目不需要这两行）。
但它仍然无法正常工作。
Android.mk 如下：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_LIB_TYPE:=STATIC
OPENCV_INSTALL_MODULES:=on
include includeOpenCV.mk
ifeq ("$(wildcard $(OPENCV_MK_PATH))","")
#try to load OpenCV.mk from default install location
include $(TOOLCHAIN_PREBUILT_ROOT)/user/share/OpenCV/OpenCV.mk
else
include $(OPENCV_MK_PATH)
endif
LOCAL_MODULE := native-activity
LOCAL_SRC_FILES := main.cpp engine.cpp
LOCAL_LDLIBS := -llog -landroid -lEGL -lGLESv1_CM
LOCAL_STATIC_LIBRARIES += android_native_app_glue
include $(BUILD_SHARED_LIBRARY)
$(call import-module,android/native_app_glue)
我收到以下错误：

有什么我错过的吗？
