Demo: java.lang.UnsatisfiedLinkError - Reason: image not found #125

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install opencv from Mac Ports ( 
http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port )
2. Download and setup javacv in Eclipse
3. Run the Demo code from http://code.google.com/p/javacv/ 

What is the expected output? What do you see instead?

Attempted to run the Demo from the javacv main page.

Please install OpenCV 2.3.1 as documented in the README.txt file, thank you.

I installed OpenCV 2.3.1 as directed and am receiving the same error:

Have you tried to 1. upgrade MacPorts and then 2. recompile OpenCV 2.3.1?

Original comment by samuel.a...@gmail.com on 2 Nov 2011 at 12:31

GoogleCodeExporter commented 9 years ago 
Yes, I have.  The package maintainer just patched OpenCV to 2.3.1  ( 
https://trac.macports.org/ticket/31818 ). I successfully upgraded opencv to 
2.3.1 and attempted to clean and rebuild the demo javacv example.  Receiving 
the same error.

The source code provided is a different version than the binary. The binary is 
looking for a 2.3 library in only the relative path lib/ , while the source 
snapshot correctly looks for 2.3.1 in the correct paths. I just compiled the 
source and it worked for me.

Hi guys,

I'm running Mac OS X Version 10.7.4 and I have OpenCV-2.4.1 in my root 
directory (/).  I have this working on two Windows machines but I can't figure 
this one out so any help would be greatly appreciated.

Cheers,
Alexei Blue.

Try to install OpenCV with MacPorts instead http://www.macports.org/

GoogleCodeExporter commented 9 years ago 
Thanks Samuel,

I'm installing with MacPorts but it seems to be getting stuck.   I've heard the 
installation can take hours but it looks like it's getting stuck installing 
llvm-3.0.  Using -v option the last line printed before nothing else happens 
is: 

"make[3] Leaving directory 
`/opt/local/var/macports/build/_opt_local_car_macports_source_rsync.macports.org
_release_tarballs_ports_lang_llvm-3.0/llvm-3.0/work/llvm-3.0.src/lib/Target/MBla
ze'"

Do I just need to be more patient or is there anything you can suggest?

Cheers,
Alexei Blue.

I have no idea, it does not install llvm here.

Original comment by samuel.a...@gmail.com on 15 Jun 2012 at 12:47

GoogleCodeExporter commented 9 years ago 
Weird.  It seems to recognise it as a dependency for me.  I have OpenCV 
download and in root but I'm using the install command.  Should I just 
recompile?  And if so can you give me a command please?

Again, cheers for your help,
Alexei Blue.

Original comment by Alexei_o...@hotmail.com on 15 Jun 2012 at 12:56

GoogleCodeExporter commented 9 years ago 
Just follow the instructions here http://guide.macports.org/ and then "port 
install opencv". If you have trouble following that guide, please ask the 
MacPorts developers, not me, thank you.

GoogleCodeExporter commented 9 years ago 
Apologies Samuel,

It looks like things are happening as they should now.  I was using +universal 
with the command which I read somewhere might help with installs using 
macports.  I ensured opencv was uninstalled (port uninstall opencv) and then I 
cleaned out the directory (port clean opencv) and finally I ran the install 
command minus the +universal and dependencies are now downloading again so with 
any luck I'll have it working shortly.

Cheers,
Alexei Blue.
