Question

我是android ndk和opencv的新手但是我已经在Eclipse中运行了一些opencv项目的示例/教程因此opencv库应该不是问题

Here i want to run this camera project from github, i think it should work

下载后将其导入Eclipse，我遇到了一个问题：

当我运行它时会停止并完成，因为无法在CameraActivity中加载库。

           ->     System.loadLibrary("PanoHDR");

我试图在网上搜索解决方案，但它们要么不起作用，要么我不理解它们。

我是否需要做类似＆＃34; ndk-build＆＃34;在某个地方让它发挥作用？

有人可以帮帮我吗？我找不到任何解决方案。

这是默认的android.mk

 LOCAL_PATH := $(call my-dir)

 include $(CLEAR_VARS)

 # Tegra optimized OpenCV.mk
 include /Users/milmil/Documents/NVPACK/OpenCV-2.4.5-Tegra-sdk-r2/sdk/native/jni/OpenCV-tegra3.mk

 # Linker
 LOCAL_LDLIBS += -llog

 # Our module sources
 LOCAL_MODULE    := PanoHDR
 LOCAL_SRC_FILES := PanoHDR.cpp Panorama.cpp HDR.cpp NativeLogging.cpp

 include $(BUILD_SHARED_LIBRARY)

当我尝试在项目的主目录中的cmd中使用ndk-build时它失败了

jni/Android.mk:6: /sdk/native/jni/OpenCV.mk: No such file or directory
make: *** No rule to make target `/sdk/native/jni/OpenCV-tegra3'.  Stop.

它应该是由Andriod.mk中的这一行引起的。

include /Users/milmil/Documents/NVPACK/OpenCV-2.4.5-Tegra-sdk-r2/sdk/native/jni/OpenCV-tegra3.mk

我尝试使用opencv sdk的路径

include /Android/OpenCV-3.1.0-android-sdk/OpenCV-android-sdk/sdk/native/jni/OpenCV.mk

并在cmd中返回

Android NDK: WARNING:jni/Android.mk:PanoHDR: non-system libraries in linker flag
s: -lopencv_java3
Android NDK:     This is likely to result in incorrect builds. Try using LOCAL_S

谢谢

=============================================== ==========================

WARNING:jni/Android.mk:PanoHDR: non-system libraries in linker flag

通过在android.mk中添加"OPENCV_LIB_TYPE=STATIC"来解决上述问题，但仍有此错误＆＃34;

[armeabi-v7a] "Compile++ thumb": "PanoHDR <= PanoHDR.cpp"
The system cannot find the path specified.

android ndk项目在加载库时出错
