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版本.

我已将原生活动(从ndk样本)转换为c ++并修改了android.mk和application.mk.

我有同样的错误(~Mat等等).

当我读到问题的答案时,我意识到我需要添加OPENCV_INSTALL_MODULES:=on and OPENCV_LIB_TYPE:=STATIC(这很奇怪,因为我有一个原生openCV的其他项目,不需要两行).

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:
