Mac Mountain Lion issues

I just downloaded MyRobotLab to my Mac which is running Mountain Lion and I can't seem to get it running.  The GUI opens and I have Welcome, MRL6890, gui, and python tabs.  When I try to install or upgrade OpenCV, I get a bunch of errors to the log:

 
140700 [MRL6890] ERROR org.myrobotlab.framework.Ivy2  - unresolved dependency: org.apache.log4j#log4j;latest.integration: configuration not found in org.apache.log4j#log4j;1.2.14: 'x86_64.64.mac'. It was required from org.apache.log4j#log4j-caller;working default

140704 [MRL6890] ERROR class org.myrobotlab.framework.ServiceInfo  - Ivy resolve error
 
I'll spare you from the rest but it keeps complaining about 'x86_64.64.mac'.  I found this on the server:
 
http://myrobotlab.googlecode.com/svn/trunk/myrobotlab/thirdParty/repo/com.googlecode.javacv/javacv/0.2/ivy.xml
 
Which contains these settings:
 
<?xml version="1.0" encoding="ISO-8859-1"?>
<ivy-module version="1.0">
    <info organisation="com.googlecode.javacv" module="javacv" status="release" revision="0.2">

        <artifact name="javacv-linux-x86_64" type="jar" conf="x86.64.linux"/>
    </publications>
</ivy-module> 
 
But there is no 'x86_64.64.mac' in the list above.
 
Here is my java version from the console:

I do have OpenCV installed and it does run when I run my own python scripts.

Hello And Welcome Superdog

I'm impressed with your diagnostic capabilities. I can also tell by the information you/ve provided that your system "SHOULD" report as x86.64.mac ..   Somewhere in the platform identification x86_64 is coming back and not being normalized.

I'll look into it now.

I'll post when the root cause has been found and fixed.

Thanks for the interest..

Ok.. got a couple problems

I believe I fixed the platform identification issue.  The continuous integration server will pick up the change and post a new version on google in about 5 minutes. The next issue which you pointed out is - missing dependencies for opencv - You say that you have a working set of binaries for OpenCV ?  Would you mind telling me what version it is .. 2.4.2  64 bit perhaps?  I have very limited access to Macs (no access to 64 bit macs)

Heh,
I'm guessing you weren't expecting me to ask for you help :)

Thanks for looking at this.

Thanks for looking at this.  I just downloaded v1006.  I can see you updated the platform ID but it's still complaining.  I am running OpenCV-2.4.3.

It's progress - the

It's progress - the identification has changed -> it's now x86.64.mac..

next changes are to the repo - doing that now..

Did you build 2.4.3 yourself ?  I'll be updating shortly from 2.4.2 to 2.4.3

FYI - The change set number is 1000 - its at the beginning - you're look ing at part of the timestamp - was 10:06 when it was built..

Change your Avatar picture .. you're certainly not a scared gopher ! :)

Checked in the x86.64.mac

Checked in the x86.64.mac definition into the repo - you should get stuff to install, but it will choke on OpenCV as I do not currently have a OpenCV 2.4.2 version for mac 64

Current options are :

  • wait till I upgrade to 2.4.3
  • if you can build and send me the binaries for 2.4.2 - I dont have access to a mac 64

I'm building 242 right now.

I'm building 242 right now.  Where do you want me to send it to?

Tried but yahoo croaked.  You can download it from my web server.  Let me know after you grab it.

Got it.. Thanks ! The output

Got it.. Thanks !

The output looks like Linux.. I removed the symbolic links since they will be meaningless by the time they are requested from the mrl repo.

Threre are two files which are different - a cv2.so (I thought all dynamic libraries on mac were always .dylib extention? no? & libopencv_haartraining_engine.a - which looks a little bit like a static library (at least in Linux extentions)  The name of the file sounds exciting...  haartraining in the past was always a PITA in opencv.

Theoretically, (If I did it right) you shouldn't get errors on the "install / download" from the repo - and you should get the contents of what is currently checked in (the stuff you just built) - from here - http://code.google.com/p/myrobotlab/source/browse/#svn%2Ftrunk%2Fmyrobotlab%2FthirdParty%2Frepo%2Fnet.sourceforge.opencv%2Fopencv%2F2.4.2%2Fx86.64.mac 

I had to change the filenames slightly because of JavaCV's JNI interface expects them without the service pack number.

They should theoretically, be downloaded into wherever you installed myrobotlab  myrobotlab/libraries/native/x86.64.mac

I added :./libraries/native/x86.64.mac to the myrobotlab.sh - so the java.library.path should be ok.

The updated bash script is in change set 1005 - uploading now.

I don't think mac requires a LD_LIBRARY_PATH environment variable - (although could be dreadfully wrong) 

Hopefully this will get you pretty close - although I have enough experience to say, things don't work out perfectly the first time :)

Good luck !

closer

The GUI opens now so that's good progress but I get a java linker error.

Great, I looked on the

Great,

I looked on the intertoobs - and it looks like mac doesnt use LD_LIBRARY_PATH like Linux.

Windows will load dynamic libraries off of PATH 
Linux uses LD_LIBRARY_PATH
Mac uses DYLD_LIBRARY_PATH ?

I added the following to the myrobotlab.sh shell script :

 

 
DYLD_LIBRARY_PATH=`pwd`/libraries/native/x86.32.mac:`pwd`/libraries/native/x86.64.mac:${DYLD_LIBRARY_PATH}
export DYLD_LIBRARY_PATH
 
...
 
You'll need to download build 1006, which is currently baking on the continuous integration server - should be done in 30 minutes..
 
Fingers crossed ..

no dice

Gets the same error. I also found 100 people with the same issue and I had already tried adding the export to my bash profile.  Always a linker error with java and C.    Let me know if you think of anything else.

Bummer...

I have limited access to a x86.32.mac so it will take me a while to do any meaningful diagnostics...

works

I downloaded the source and was able to get it compiled and working under NetBeans.  It doesn't run from the IDE though, I'll figure that out next.  I had to copy over the hidden .ivy folder to the dist folder that was created when I built the project.  

My mac has an HD camera which scrolls way off the screen when it turns on and I can't access the filters and sliders on the right on the openCV screen.  I'll look at that too.  

Thanks for your help and work on this project.

Yay ! The .ivy folder is

Yay !

The .ivy folder is built when a service is installed - it is a local cache of the repo and built during runtime.

So if a complete package downloaded now from google does not work, how is it you got the shell script to work now?  What is the magic part I was missing?

You can put in a PyramidDown filter in Python while the camera is capturing.

You should be able to copy paste the following in the python tab and have it work for you.

 

 

opencv = runtime.createAndStart("opencv","OpenCV")
 
# scale the view down - faster since updating the screen is 
# relatively slow
opencv.addFilter("pyramidDown1","PyramidDown")
 
# begin capturing
opencv.capture()
 
# set focus on the lkOpticalTrack filter
opencv.setDisplayFilter("pyramidDown1")
 
Glad to hear we're making progress...
