Install Javacv and opencv o Windows

[Menegussi]

Hi!

I have the opencv2.2, javacv and Eclipse on Windows 7 and all work fine!

Now I'm installing, in another computer with Windows 8, and I have the followed message when i run the program:

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Users\AndreW.M\AppData\Local\Temp\jniopencv_core5538018260107553126.dll: Can't find dependent libraries

Below I describe what I made:

1- Unzip OpenCV 2.4.4 (only unzip, nothing installed like OpenCV2.2

2- Unzip javacv-0.4-bin 

3- CLASSPTATH with:  D:\OpenCVJavaCV\opencv\build\x64\vc10\bin;D:\OpenCVJavaCV\javacv-0.4-cppjars\javacv-cppjars

4- Added External Jars in the project, locates at javacv-0.4 bin

Can you help me?

Thanks!

Did you try the lastest version of opencv? In m'y memory is 2.4.4 or 2.4.2

Yes, I did! i'm using opencv 2.4.4. But I don't know if I was installed correctly. I just unzipped the file containg the opencv. In opencv 2.2 version, I installed with a .exe that was registred in windows registry.

I don't know if I did something wrong. I'm not sure if my javacv is 64 or 32 bits, because I just unzipped it too!.

Thanks

Re-download it and put it at  C:/opencv/

Then add it to your path

[André Menegussi]

I put the opencv in D:\OpenCV\opencv2.4.4. Is it a problem?

Which JAR files are in your CLASSPATH exactly? It looks like
opencv-2.4.4-windows-x86.jar and opencv-2.4.4-windows-x86_64.jar are
missing. Please add them to your CLASSPATH as instructed in the
README.txt file and let us know how that goes...

Hi Samuel,

The files opencv-2.4.4-windows-x86.jar and opencv-2.4.4-windows-x86_64.jar and in  the D:\OpenCVJavaCV\javacv-0.4-cppjars\javacv-cppjars directory. This directory is in my CLASSPATH. See in the previous message!!

Do I make any mistake or I'm not doing something else?

Thanks!

I never said to put the directory containing the JAR files in your
CLASSPATH, I said to put the JAR files themselves in your CLASSPATH, as
explained in Java's documentation here:
http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html

Ok Samuel! I understood wrong! Sorry! :)

Hi Samuel, sorry I'm newbie in java and javacv/opencv.

In javacv (using OpenCV 2.2) I have a directory with avcode-xx.dll files. I downloaded this files from the website.

I'n not finding these files in the installation of OpenCV 2.4.4. Is it normal?

Thanks,

André

Yes, they are available here as indicated in the README.txt file:
http://code.google.com/p/javacv/downloads/list

[André Menegussi]

Hi Samuel, 

Sorry about this question again, but in the http://code.google.com/p/javacv/downloads/list I not found the avcodec-xx.dll in any zipped file! I read the readme.txt and I'm not knowing how to do that!

Thanks in advance!.

Just download all the ZIP files and put all the JAR files in your
CLASSPATH: That will work :)

[André Menegussi]

Ok, I'll try!

I'm thinking like Opencv 2.2 and javacv instalation!! :)

After I'll let know!

Thanks!!
