How to Install OpenCV2.0 in Mac OS 10.6.1 (Snow Leopard)

Question

Hi, I am not a Unix guy, so I have been trying to install openCV 2.0 for days with out success. I just downloaded the opencv library form sourceforge from this page: http://sourceforge.net/projects/opencvlibrary/ Does any one know the exact unix terminal commands for installing it?

please don't say "go to google", I already did. I found this: http://opencv.willowgarage.com/wiki/InstallGuide and this http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port but the explanations are not very good for unix beginners.

installations always fails in the end.

It would be great if I can make a framework. for example OpenCV.framework from the current source, So I can use it with Xcode, and Cocoa easier.

thanks

I did:

downloaded it. extracted it.

cd Downloads/OpenCV-2.0.0
./make_frameworks.sh

and got this when linking all the .o files.

mv -f .deps/saving.Tpo .deps/saving.Plo
mv -f .deps/logger.Tpo .deps/logger.Plo
mv -f .deps/index_testing.Tpo .deps/index_testing.Plo
libtool: link: (cd .libs/lib_clapack.lax/lib_clapack_floatstore.a && ar x "/Users/nacho4d/Downloads/OpenCV-2.0.0 3/build_i386/3rdparty/./.libs/lib_clapack_floatstore.a")

Creating universal Framework
=============================================
cp: build_ppc/OpenCV.framework: No such file or directory
lipo: can't open input file: build_ppc/OpenCV.framework/OpenCV (No such file or directory)
Done

!

Do I need to do something before running the shell script?

EDIT: For the interested, I wrote a post on how to install and use OpenCV 2.1.1 on Macs here: http://nacho4d-nacho4d.blogspot.com/2010/07/blog-post.html

Answer 1

Ok, I just solved it. In fact there is a bug somewhere, because if your path contains a space shell scripts will fail.

for example.

$pwd
/Users/nacho4d/Downloads/OpenCV-2.0.0 3
$./make_frameworks.sh

this will fail because current folder "OpenCV-2.0.0 3" has a space.

It took me many hours to realize this. ;(

Answer 3

I had a problem compiling on Snow Leopard too, but was able to get it to work by following the instructions at: http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port

The only modification I had to make was also to disable ffmpeg inside of ccmake

The GNU autotools methods (make && make install) are being outdated. Volunteers to edit this section?

mkdir opencv/build cd opencv/build cmake .. ccmake .

If you are on Snow Leopard, hit 't' to toggle advanced mode. Set CMAKE_CXX_COMPILER="/usr/bin/g++-4.0" and CMAKE_C_COMPILER="/usr/bin/gcc-4.0" and then continue with the following steps.

Hit 'c' to configure. Hit 'g' to generate the config file and exit ccmake.

make -j8 sudo make install

If you hit the following build error:

/Users/awagner/Developer/opencv2/src/highgui/grfmt_tiff.cpp:292: error: ‘fmtSignTiffII’ was not declared in this scope make[2]: * [src/highgui/CMakeFiles/highgui.dir/grfmt_tiff.o] Error 1 make1: * [src/highgui/CMakeFiles/highgui.dir/all] Error 2

you can get the build to complete by commenting out line 292 of src/highgui/grfmt_tiff.cpp and running make again. (This probably breaks something in TIFF export, but the build at least completes)
