Android Studio NDKリンカーのエラー 'cv :: _ OutputArray :: _ OutputArray（cv :: Mat＆）'への未定義の参照

Question

NDKを使用するAndroidプロジェクトで作業しています。もの。

：私は、次のリンカエラーを取得しています（パスをchaningことによってそれを検証する）すべてのOpenCVのライブラリをリンクし、正しいパスを指定していますが

LOCAL_PATH := $(call my-dir) 

include $(CLEAR_VARS) 

include path/to/OpenCV.mk

include $(BUILD_SHARED_LIBRARY) 

：ここに私のAndroid.mkがどのように見えるかです

これはlinkです。ここでスキャナアプリのデモをダウンロードし、scan.cppファイルに変更を加えてライブラリを再構築しようとしています。 私はAndroidスタジオで外部ツールとしてndk-buildを作成しましたが、ndkパスも確認しました。私はここで何が欠けていますか？どんな助けもありがとう。

Answer 1

修正。私はそれがどのように修正されるのか正確な理由はわかりません。私はAndroid.mk、Application.mkとOpenCV.mkで行ったすべての変更を元に戻す、今私のAdnroid.mkは次のようになります。

LOCAL_PATH := $(call my-dir) 

include $(CLEAR_VARS) 
OPENCV_INSTALL_MODULES:=on 
include $(LOCAL_PATH)/sdk/native/jni/OpenCV.mk 

LOCAL_MODULE := Scanner 
LOCAL_SRC_FILES := scan.cpp 
LOCAL_LDLIBS += -lm -llog -landroid 
LOCAL_LDFLAGS += -ljnigraphics 
include $(BUILD_SHARED_LIBRARY) 

そしてApplication.mk：

APP_STL := stlport_static 
APP_CPPFLAGS := -frtti -fexceptions 
APP_ABI := all 
APP_PLATFORM := android-14 

THA私は正しいパスか、私のライブラリファイルをspecyfying見逃していると思います

（.soのと.A）異なるバージョンであるかもしれない。そして、ここのように私OpenCV.mkがどのように見えるかですヘッダファイルが含まれています。誰かが他のアイデアを持っているなら、コメントを投稿してください。
