Provide complete build instructions for javacv and its dependencies

[GoogleCodeExporter]

Right now, there is no simple step by step build instructions geared toward 
java developers to build javacv from source.

The instruction should include details how to set up and compile all 
dependencies, and how to build javacv native libraries for different platforms.

The info that is present right now project home page is geared more towards 
people that are already familiar with used libraries than toward java 
developers that never used them before.

I've just committed a new `pom.xml` that builds without any other dependencies 
than OpenCV, which should simply the build process. Let me know if this 
satisfies you, and if you still feel that nightly snapshots or more detailed 
build instructions are still required, thank you

Hi Samuel,

Thanks for all of your efforts on this.  I am running into dead ends trying to 
compile as well.  At first I didn't know (and still don't) where to place 
javacpp.jar so that Maven would find it.

Then I noticed you changed things up so that we could skip the javacpp 
dependency:
mvn package -Pall -Djavacpp.skip=true

Unfortunately, that doesn't seem to do the trick either.  I run into:

That's just the Maven versioning system doing its thing... I'm not sure how to 
effectively use it yes, so just make sure you install JavaCPP from source as 
well.

@florin As mentioned in the README.txt file, the requirements include OpenCV 
2.4.2. On Mac OS X, we can install that easily with MacPorts, for example.

Hi Samuel, I am unfortunately still running into the same set of errors, about 
100 instances of various classes not being able to find StdVector:

[ERROR] 
/Users/vanevery/Desktop/javacv/src/main/java/com/googlecode/javacv/cpp/opencv_st
itching.java:[970,62] cannot find symbol
[ERROR] symbol  : class StdVector
[ERROR] location: class com.googlecode.javacv.cpp.opencv_stitching

They all involve not being able to find StdVector.

JavaCPP compiles fine and through the new pom.xml if I don't have the jar file 
in place it downloads correctly so I know that it is there. 

Just can get around not being able to find StdVector.

I'm having the same issue as savanev right now, I'm quite new to this, this is 
my first experience with Maven so I apologize if I'm missing something obvious.

I've run mvn install no javacpp, put javacpp.jar in my classpath.. and also put 
the jar directly in the JavaCV directory.  

Thanks for your time.

Hi Version135b and Samuel,

I am new to Maven as well, trying to wade my way through.

I see that the version of JavaCPP that gets downloaded automatically is 
actually missing the StdVector class.  It is placing it in ~/.m2/...  

The version that I compile from source has it so I am attempting to try to 
figure out how to compile JavaCV with my version of JavaCPP rather than the 
automatically downloaded version.

Original comment by savanev...@gmail.com on 21 Aug 2012 at 3:13

interesting.. I cannot find StdVector in my source for JavaCPP or the jar.  Are 
you certain it is supposed to be there?

Original comment by Version1...@gmail.com on 21 Aug 2012 at 3:21

[GoogleCodeExporter]

I definitely have it in the version I checked out.  It seems to be in the repo:

http://code.google.com/p/javacpp/source/browse/src/main/java/com/googlecode/java

Unfortunately, not certain of anything..

interesting.. when i search from top level that doesn't come up.  I notice that 
I'm missing StdString too.. I'm going to try and get the jar built with these 
files and see if i can catch up to you :)

Ok, under tag 0.1 and 0.2 those files are missing, tag <none> contains them.

Ok, i got it to work by pulling the master with git (i dunno if that made sense 
i have little experience with git as well.. ) i then did mvn install for 
javacpp.. after that i did mvn install in javacv (without clean!) i think clean 
will replace the installed jar for javacpp.. not sure though.

Yes, it is building and installing as it should.  I am running on MacOS X 10.8 
with OpenCV installed via Homebrew.

My goal is to build this for Android though so I am not sure I am done.

[GoogleCodeExporter]

For Android, you need to set some options for JavaCPP as explained here:
    http://code.google.com/p/javacpp/#Instructions_for_Android
In the case of JavaCV, I've included in the pom.xml file a property named 
javacpp.options, whose purpose should be pretty obvious, so we can build it 
this way:
    mvn package -Djavacpp.options="-properties android-arm -Dplatform.root=<path to android-ndk-r8> -Dcompiler.path=<path to arm-linux-androideabi-g++>"

I'm now getting errors about finding the openCV library.. i've added 
C:\opencv\build\include 
to the PATH and classpath.. was there some other var that needs configuring as 
well?

The error is looking for opencv2/core/core_c.h which lies inside 
C:\opencv\build\include

Thanks so much for your help so far.. Much appreciated.

Which var is used by maven to look for these files?? I'm not finding stdlib or 
jni headers either.. 

I'm sure its just a matter of plugging in the correct directories for these 
files now.

I've gotten rid of the stdlib and jni errors, what VAR should contain the 
include path for opencv?  I'm still getting opencv2/core/core_c.h no such file 
or directory issues.
LIB OPENCV and INCLUDE setup, classpath and path are both pointing  to opencv's 
build/include directory too.  Thanks for your time.

I am having some serious problems with building JavaCV on Ubuntu for android, 
with most of the problem right now coming from OpenCV. For some reason the 
cmake isn't installing the libs or the headers. Moreover, I can't even seem to 
find the headers themselves. I was able to get the 'include' folder from a 
windows build i managed to create, but now receiving an error regarding an 
undefined reference to some TBB methods. 

If anyone has the openCV static libraries and headers, and could share it it 
would be beautiful. I want to make sure i have built OpenCV properly.

Thanks,
K

@klommenz OpenCV requires a little patch that's part of the cppjars archive. 
Make sure to apply that patch and also execute the build process in a way 
similar to what is in the build_opencv-android-arm.sh script file.

Original comment by samuel.a...@gmail.com on 21 May 2013 at 1:27

[GoogleCodeExporter]

I have used the build_opencv-android-arm.sh script file for my build. I am 
going to remove everything from my file system, and start a clean copy now that 
i know where the pitfalls are.

I will update in case the problems are persisting.

Thanks

Original comment by klomm...@gmail.com on 21 May 2013 at 1:29

[GoogleCodeExporter]

Ok, i made an entirely fresh copy of the JavaCV project, along with all its 
libraries, and used the build script files you have provided, as is.

OS : CentOS
NDK: r8e 64bit
FFMpeg: 1.2
OpenCV: 2.4.5
X264: Latest version
JDK: 1.7
Maven: 3

Right now I am missing the header file core_c.h (and all the other opencv 
headers with it). It's quite evident that the script is not installing the 
headers anywhere in the file system, and also the libs are kept under opencv's 
libs subfolder. when i enter make/cmake install, it reports that it has no 
install instructions. I have already came across this problem in my previous 
attempts. Does anyone have any advice on how to get cmake to produce the 
correct headers, or could just provide me with the correct headers for android, 
so i can continue and eliminate other problems?

I am attaching build logs for opencv and ffmpeg.

Thanks

@ kIommenz I really wished that you could make a more detailed step by step 
guide. It is such a time waster for someone has already figured it out step by 
step.

@samuel

I'm trying to use ffmpegframegrabber but wanted to set option rtp_transport = 
tcp.
av_dict_set(&optionDictionary, "rtsp_transport", "tcp", 0); so I want to modify 
your source and compile. (unless there is a way to set it without recompiling 
javacv?)

Even though I got FFmpeg working on iOS and BlackBerry, but they are native. I 
know when it comes to building JavaCV for Android, I would run into a lot of 
trouble. I haven't used Maven before and I know less about JNI wrapper.

Ok here it goes:

When you say OpenCV is the dependency for building JavaCV. I hear your words 
but cannot think of the way to go forward.

I used specifically macport to install opencv (as you stated in Aug 15, 2012), 
which I assume that I have that dependency fulfilled. But after running mvn 
package -Djavacpp.options="-properties android-arm -Dplatform.root=<path to 
android-ndk-r8> -Dcompiler.path=<path to arm-linux-androideabi-g++>" it still 
asks for core.hpp.

Then i read your words on
"If you're trying to compile for Android, you need the OpenCV from here, as 
stated in the README.txt file: 
http://code.google.com/p/javacv/downloads/list"

Again I head the words, but don't know how the opencv-2.4.6.1-android-arm.jar 
is gonna help for compiling javacv. Should I extract the .so and put it 
somewhere else? or should I put the jar file somewhere?

Or you point us to that link so that we can build our own opencv.jar using the 
.sh script as example to follow?

Could you please enlighten me, I'm pulling my hair out...

Original comment by juiy...@gmail.com on 31 Oct 2013 at 10:07

[GoogleCodeExporter]

Yes, I don't think there is any generic way to set options through 
FFmpegFrameGrabber and av_dict_set() at the moment, but if you have a patch to 
enhance that, though, please send it! thanks

About building JavaCV, the best way is to simply recompile everything from 
scratch, first OpenCV and FFmpeg themselves, through the scripts. We still need 
to run "make install" after the scripts run, and the install directories might 
not quite end up where JavaCV expects them, but it should be pretty 
straightforward to figure that out from the errors you get with "mvn package", 
and yes that's pretty much it.

So, start with building OpenCV and see that goes...

[GoogleCodeExporter]

@sam

Thanks for your kind words. In the end, I just subclassed FramGrabber class 
without compiling and I should be able to send a patch on FFmpegFrameGrabber 
through to specify the tcp. I will do that after my project here let me have a 
breather.

I lost some of my hair. I should read up on mvn...
