Android“沒有這樣的文件或目錄”錯誤？

Question

安裝ADT並添加CDT和NDK並添加OpenCV庫后，會出現此錯誤

**** Build of configuration Default for project OpenCV Tutorial 2 - Mixed Processing     ****

C:\android-ndk-r9\ndk-build.cmd 
jni/Android.mk:5: ../../sdk/native/jni/OpenCV.mk: No such file or directory
make: *** No rule to make target `../../sdk/native/jni/OpenCV.mk'.  Stop.

**** Build Finished ****

這是Android.mk代碼

    LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

include ../../sdk/native/jni/OpenCV.mk

LOCAL_MODULE    := mixed_sample
LOCAL_SRC_FILES := jni_part.cpp
LOCAL_LDLIBS +=  -llog -ldl

include $(BUILD_SHARED_LIBRARY)

Answer 1

更改Android.mk以便include包含OpenCV.mk的絕對路徑。 例如：

WIN: include d:\dev\OpenCV-2.4.6-android-sdk\sdk\native\jni\OpenCV.mk
Linux: include ~/mydevdir/OpenCV-2.4.6-android-sdk/sdk/native/jni/OpenCV.mk

Answer 2

代碼不在它期望的位置。 它期望OpenCV.mk文件存在於目錄../../sdk/native/jni/OpenCv.mk

Answer 3

您是否知道在使用include時，相對路徑從項目目錄開始，而不是project / jni目錄。 確保您的目錄結構如下所示，

• 根

  - sdk

  - 項目

和你的包含行：

include ../sdk/native/jni/OpenCV.mk
