No binaries for Linux on ARM (Gumstix, PandaBoard, Trim-Slice, Raspberry Pi, etc.) #184

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Compiling and installing OpenCV on a Gumstix board with Linux.
2. Creating a javacv project on Windows Eclipse and exporting a .jar file.
3. Running the program with "java -jar test.jar" 

What is the expected output? What do you see instead?
I get the error:
"no jniopencv_core in java.library.path"

What version of the product are you using? On what operating system?

Please provide any additional information below.
The lib directory with the OpenCV .so files is in my PATH. javacv.jar, 
javacpp.jar, and javacv-linux-x86.jar are all in my project directory and added 
to the build path using Eclipse.

GoogleCodeExporter commented 8 years ago 
I don't think the Gumstix uses an x86 CPU... ? In addition to OpenCV, could you 
try to recompile JavaCV using the Gumstix's SDK as well and try again? Thank you

So, did you get it working? I guess I will be marking this as a RFE... If you 
or anybody else could contribute any builds, they would be most welcome! Simply 
attach them here, thank you

@Manoj Thanks!! If you could also compile it for FFmpeg, etc. I'd make

not provided with javacv 0.5?

Hi Samuel,
We manage to get the linux-arm jar compiled but it's not working. 
For some reason we get an exception in the execution related with TBB. We have 
tried compiling opencv 2.4.5 with and without the TBB feature, but that wasn't 
helping. Does this ring some bell on your side? 
I'm looking forward to send the jar as soon as we get it working. 

Cheers

Original comment by sala...@gmail.com on 10 Jun 2013 at 8:38

GoogleCodeExporter commented 8 years ago 
Looking at the javacpp/src/main/java/com/googlecode/javacpp/Loader.java  class 
I've noticed that there could be a problem identifying the platform (linux-arm) 
there and for that reason the Loader tries to get the TBB libs in the mix. Any 
ideas where this could be invoked? Do you remember if inside JavaCV or JavaCPP 
the TBB classes are required to be loaded?

Original comment by sala...@gmail.com on 10 Jun 2013 at 8:53

GoogleCodeExporter commented 8 years ago 
Is this really necessary? 

src/main/java/com/googlecode/javacv/cpp/opencv_core.java:127:        

include={"<opencv2/core/core.hpp>", "opencv_adapters.h"}, 
link="opencv_core@.2.4", preload="tbb"),

Original comment by sala...@gmail.com on 10 Jun 2013 at 1:28

GoogleCodeExporter commented 8 years ago 
Hi everyone,
We get it working here after two modifications:
1) we removed the preload="tbb" sentence in the opencv_core.java:127 file
2) we manually create a soft link from libjvm.so to libjvm.so.0

Now the problem is to locate the raspberry camera device with the 
OpenCVFrameGrabber, that it doesn't seem to work using the following 
constructor OpenCVFrameGrabber(""). 
Any ideas on how to list all the available camera devices?

Cheers

GoogleCodeExporter commented 8 years ago 
The `libjvm` issue is related to this bug report, which I'll be working on 
shortly:
http://code.google.com/p/javacpp/issues/detail?id=33

Removing `preload="tbb"` shouldn't change anything. What error message do you 
get if you do not remove it?

IIRC what Jeremy said, I don't think Linux supports the camera device on the 
Raspberry Pi. He might have more info about that at this point, so please ask 
him about that, thanks.

Hi folks,
I'm sorry that I can't provide the arm build atm.

For your information, direct access of the CSI camera module of the Raspberry 
Pi is not possible at the moment, as there is no V4L driver.
The Raspberry Pi foundation said they are working on it though.

The best workaround for the moment is to call their "raspistill" command from 
your programm and read the resulting .jpg image from OpenCV...

GoogleCodeExporter commented 8 years ago 
Hi Jeremy, 
We manage to get the build working and we can provide the linux-arm.jar to 
anyone interested in it.. it should be provided with the release file. 
We were looking at it and we reach at the same conclusion, it's not possible to 
access directly.
We were also trying to use raspivid which allows us to stream the video out and 
then pick up that streaming with java-cv. That seems to be working correctly, 
but with lots of delay. 
I'm looking forward to see what the Raspberry Pi foundation has to deliver. 
Samuel, thanks a lot for your help, let me know if you want me to write a wiki 
about how to install java cv in the Pi and also let me know if you wanted to 
get the linux-arm.jar. 

Cheers

@salaboy Upload your files to Google Drive or something and post the URL here, 
thanks!!

As for a Wiki page, it would be great to have one that explains the build 
process in detail, yes. Could you also do it for Linux in general and maybe 
Android and what not? I'm sure you can manage :) In any case, I gave you Wiki 
edit access, so please feel free to contribute what you can, thanks!

HI guys, I finally had time to finish the blog post about the installation 
process:
http://salaboy.com/2013/06/14/using-javacv-in-the-raspberry-pi-linux-arm/

Here are the direct links to the compiled jars: 
https://drive.google.com/folderview?id=0B0lFIImWo61bc3pTTHdZN3NmNkE&usp=sharing

I don't mind providing new versions of the jars for the next release of JavaCV. 
I believe that they should be delivered inside the distribution files, so 
please contact me back if you need me to produce those jars. 
The Raspberry Pi it's getting popular and having these jars out of the box can 
save people a lot of time.

Another thing is adding these compiled jars to the Maven repository, I think 
that it will be extremely useful if you just publish these artifacts there, so 
people just forget about all the compilation steps. 

Cheers

@salaboy If you can create a JAR file that contains all the binary files, and 
not just the ones for OpenCV, I'll be glad to upload it with all the rest to 
the little repo! Let me know if you get there, thanks.

Hi Samuel,
I'm definitely a newbie here, what do you mean with all the binary files and 
not just the OpenCV ones? as far as I understand the only new thing that I've 
provided is the javacv-linux-arm.jar which contains the binary files for 
OpenCV, can you specify which other binaries do you want me to deliver?
Cheers

Original comment by sala...@gmail.com on 17 Jun 2013 at 9:40

That's one of the reasons why we need better build instructions :) Try to 
compile with this command:
    $ mvn package -Pall -Djavacpp.options="-Xcompiler -fpermissive"
and when that succeeds you should get everything.

AFAIK, JOGL doesn't have any Maven artifact. That's why it's not in the pom.xml 
file. You could limit the dependencies to only the set required to get a full 
build of the native libraries:
    $ mvn package -Pmarkers,ffmpeg,dc1394,flycapture,openkinect,videoinput -Djavacpp.options="-Xcompiler -fpermissive"

You won't need to build ARToolKitPlus, just have it under the same parent 
directory as javacv. In any case, the path is indicated in annotations at the 
beginning of ARToolKitPlus.java.

Original comment by samuel.a...@gmail.com on 22 Jun 2013 at 10:28

GoogleCodeExporter commented 8 years ago 
Can you be a little bit more specific? I've downloaded ARToolKitPlus from the 
JavaCV webpage, and then I've placed in these 3 places to see if it work 
without any luck (projects is my root dir): 

1) projects/javacv/ARToolKitPlus/

2) projects/ARToolKitPlus/

3) projects/javacv/target/ARToolKitPlus/

Any idea?
I notice that template.h is inside the include dir in the file that you provide 
in the main page.

Original comment by sala...@gmail.com on 22 Jun 2013 at 2:15

None of the above: You would have to put it in "projects", but you can also 
change ARToolKitPlus.java to fit your system.
