Hello, I'm using OpenCV2.4.3 on Eclipse. I need to add the correct path to GCC C++ Linker on MINGW libraries as shown in the figure below. Where is the location of the opencv lib and the libraries needed to add on GCC Linker? Please guide me.

Update AVD

Thank you. No errors now. But when I tried to run the samples, the screen displayed 'camera not supported'. Full details http://answers.opencv.org/question/4500/device-not-found-camera-not-supported/

Hello again! I tried to run Sample1Java from OpenCV Samples on an emulator. I installed the OpenCV_2.4.3_Manager_2.0_armeabi.apk but my emulator screen displayed 'It seems that your device does not support camera(or it is locked). Application will be closed.' How to resolve this issue? (Setup and error below)

AVD Setup

Error

Are you using an emulator? If yes, Tutorial 3 and 4 use OpenCV Native Camera which may not work with emulator.

Hello again! I imported the OpenCV-Android samples in Eclipse. I installed Eclipse,NDK,SDK from here (http://docs.opencv.org/2.4.1/doc/tutorials/introduction/android_binary_package/android_binary_package.html) but got these errors. Please I've been struggling for 3 weeks.

I did that already. The only way to compile is through commandline.

@Andrey Pavlenko, I also tried that. Still no effect.

My commandline can detect ndk-build.cmd. I don't know if I correctly compiled the file. Now I want to know what will I do next. Here is my post http://answers.opencv.org/question/4149/opencv-ndk-buildcmd-next-move/?comment=4152#comment-4152

@Kirill Kornyakov Yes. In Properties->C/C++ Build->Environment. NDKROOT=C:\android-ndk-r8b. @Oscanto. I'm using Windows7 so removing .cmd is not needed.

Ok @manmedia. I'll give updates few hours from now. Thanks a lot :D

I think Eclipse doesn't recognize my ndk-build.cmd. So I used windows commandline to build OpenCV Sample-Tutorial 3(Adding Native OpenCV). I wonder if it has errors or is it ready to produce an output. How will I know if it's ready to run? If yes, how will I see the output? What will be my next step?

Yes man, I followed the manual. No worries about the frustration. I tried using the commandline. I can't post the picture here. So, kindly go to the original link. http://answers.opencv.org/question/4137/error-cannot-run-program-ndk-buildcmd/

Yes man, there is. I don't know why Eclipse can't recognize the path to my ndk-build.cmd.

Hello @Chayan, I am also in OpenCV Tutorial 3 and produced lot of errors. I know you can help me about my problem. How did you resolve the error "Cannot run the program ndk-build.cmd: The system cannot find the file specified" in Tutorial 3? Please help. My original post http://answers.opencv.org/question/4137/error-cannot-run-program-ndk-buildcmd/

I can't find the solution to my problem. It's about ndk-build.cmd. Here is the link http://answers.opencv.org/question/4137/error-cannot-run-program-ndk-buildcmd/

Hello again, I imported the sample files from OpenCV4Android-SDK. I used Eclipse, installed the CDT and the NDK but I got this kind of error. "Cannot run program "\ndk-build.cmd": The system cannot find the file specified." Why is this happening? Please help!

Here is my directory and the ndk-build.cmd ---------------------------------

-------And my Environment Variables -------------------------

Congratulations. Good for you. :)

I installed the tools and followed the instructions. But there's a problem in Building application native part from Eclipse (CDT Builder). I've encountered errors on ndk-build.cmd. It's in my directory but Eclipse doesn't recognize it. I really need to proceed. How did you installed your opencv Sir?

Then what will I use? How did you manage to install your opencv in eclipse? Please.

Please help me install OpenCV4Android on Eclipse.

Here is the link for the OPENCV slides. Some links in the slides (slide 7 link for detailed instruction) gave 404 errors. Do you think it's UPDATED? https://docs.google.com/presentation/d/1EO_1kijgBg_BsjNp2ymk-aarg-0K279_1VZRcPplSuk/present#slide=id.g14d10b04_0_59

@Andrey Pavlenko. I downloaded the new Android ndk called android-ndk-r8b-windows. I extracted the file to C:\android-ndk-r8b and added it to the PATH (System Properties->Advanced System Settings->Environment Variables) . This gives me the error "C:/android-ndk-r8b/ndk-build.cmd" is not found in PATH". I can see the ndk-build.cmd in the directory but Eclipse didn't detect it.

I tried the new tutorial but it's also old. Can you help me install the new OpenCV4Android? Please. I'm desperate.

Hello, I am very new to OpenCV-Android. I have problems installing OpenCV4Android-SDK. The instruction on http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html says "Install the Manager.apk and the corresponding binary_pack.apk depending on the device CPU..." I don't know the kind of APK to install. I also don't know what does ArmV7A, X86, Armeabi-Armv7A, MIPS mean. Can you help me install the right apk? Here is the screenshot to my available APK located in C:\Work\OpenCV4Android\OpenCV-2.4.3-android-sdk\apk

Hello again! I imported the OpenCV samples in Eclipse and encountered errors like "C:/.../android-ndk-r4-crystax/ndk-build.cmd" is not found in PATH.

How can I resolve these errors?

I downloaded android-ndk-r4-windows-crystax-4.zip from this website http://www.crystax.net/android/ndk-r4.php but I can't find ndk-build.cmd . Screenshot of my directory.

Screenshot of the errors.

Thank you @Simone. I'll try your answer and come back if I have any problems. Do you have any links for OpenCV4Android installation guide except this http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html ?
