Using Emgu CV on Mac OSX

Yesterday, I thought of trying to run Emgu CV on Mac OSX.

I write what I did for that here.

*Emgu CV is a OSS Open CV wrapper for .Net framework.

OS: Mac OSX Snow Leopard (10.6.4) failed

Mac OSX Leopard(10.5.8) succeed!

1. Installing Mono and Monodevelop (for now you dont really need Monodevelop)

http://www.mono-project.com/Main_Page

== Japanese problem ==

You need to specify a font that can be used for your own language if you are using Multi-bytes.

Create next file with admin authority.

/Library/Frameworks/Mono.Framework/Version/Current/etc/pango/pango.aliases

Write a line like below.

"Lucida Grande" = "Hiragino Kaku Gothic Pro"

==================

2. Installing depending libraries via Macports

sudo port selfupdate

sudo port upgrade outdated

sudo port install cmake

sudo port install ffmpeg

sudo port install tiff

3. Get a source code from SVN repository

svn co https://emgucv.svn.sourceforge.net/svnroot/emgucv/trunk emgucv

4. Creating make file by cmake
cmake -DBUILD_NEW_PYTHON_SUPPORT:BOOL=FALSE -DBUILD_TESTS:BOOL=FALSE .

5. Executing make

make

6. Running samples
move to bin directory
set value to read library from current directory

export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH

execute a sample

mono Example.PlanarSubdivision.monoexe

Error!

System.DllNotFoundException

7. Setting Log level and execute again

MONO_LOG_LEVEL=debug mono Example.PlanarSubdivision.monoexe

It seems 64bit is not supported by Mono 2.6.7 so that it is hard to run on Snow Leopard.

8. Trying to build with 32bit option

cmake -DCMAKE_OSX_ARCHITECTURES=i386 -DBUILD_NEW_PYTHON_SUPPORT:BOOL=FALSE -DBUILD_TESTS:BOOL=FALSE .

got an error at make command.
It said something like Open CV should be 64bit...
hmm, I gave up with Snow Leopard ...

9. Trying with Leopard (10.5.8)
Mostly same as above however library path was different so set as below.

export LD_LIBRARY_PATH=../lib:.:$LD_LIBRARY_PATH

I could run the sample!
