的Android NDK给予的错误，同时在Eclipse编译 [英] Android ndk giving errors while compiling in eclipse
本文介绍了的Android NDK给予的错误，同时在Eclipse编译的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
以下是我在Eclipse的Android应用程序的Android.mk文件。

更新所述opencv_mk_path和LOCAL_C_INCLUDES后，将应用程序没有编译NDK通过。我曾尝试各种可能的解决方案，但没有运气。以下是发生错误：

请帮我出这一点。
解决方案
-
为
LOGD（），用LOGD（％s时，out.str（）c_str（））; -
获得
PTR＆LT; ORB＆GT; detector1，你应该使用ORB ::创建（），不是新的ORB（）
Following is the Android.mk file of my android application in eclipse.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_CAMERA_MODULES := off
OPENCV_MK_PATH:=C:\Users\rabbia\Downloads\OpenCV300androidsdk1\OpenCV-android-sdk\sdk\native\jni\OpenCV.mk

include $(BUILD_SHARED_LIBRARY)
After updating the opencv_mk_path and local_c_includes, the application is not compiling through ndk. I have tried every possible solution but no luck. Following are the errors that occured:

解决方案
for
LOGD(), useLOGD("%s", out.str().c_str());to get
Ptr<ORB> detector1, you should useORB::create(), notnew ORB().
这篇关于的Android NDK给予的错误，同时在Eclipse编译的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
