Is someone able to give me a quick tutorial how to install cvBlob on osx 10.7 ? On their site they only mention linux and windows. A link would also be welcome, because i can't find any tutorial how to do this.

I tried to do it based on the linux tutorial and did the cmake with an extra entry with referes to my opencv folder. The cmake worked but When i do the make command, i get this error :

what do i have to do ?

the cmake:

Thx in advance

To give a quick overview how i got cvBlobs working :

1) download the latest cvBlob

2) Extract it

3) Navigate to cvBlob/cvBlob and open the CMakeLists.txt

4) Add this code : 

if(APPLE)
   target_link_libraries(cvblob ${OpenCV_LIBS})
endif()

UNDERNEATH 

add_library(cvblob SHARED ${cvBlob_CVBLOB})

5) open your cmake program and select the path to the folder where said cmake file is. And select a path where you want your libs to be

6) Execute it

7) Open terminal, go to the folder

8) Then you get a makefile which you can sudo make install

9) To use the cvBlob in xcode you have to add the 'libcvblob.dylib' to the other linker flags.

About your

No matching constructor for initialization of 'cvflann::LshIndexParams'

you might want to try changing your compiler to LLVM GCC 4.2 in XCode.

Try adding -m32 to CFLAGS/CXXFLAGS in cmake.

  • I've did the cmake for xcode. when i open this xcode project i try to compile this for 32 & 64 bit . When doing this i get this error : No matching constructor for initialization of 'cvflann::LshIndexParams'. and Call to function 'operator<<' that is neither visible in the template definition nor found by argument-dependent lookup . – Olivier_s_j Nov 30 '11 at 11:25
  • Hey, it compiled correctly in console and failed to link because your opencv library is 32bit only. So I said how to fix this (compile cvblob also only for 32bit). Now you created Xcode project instead - I don't know why it doesn't even compile! – pronvit Nov 30 '11 at 11:35
  • My opencv is not 32 bit only. It's not a problem with the architecture. It's a problem considering a path. Which one and why, i'm having a look at. I just wondered if someone did this before and if someone might be able to tell me which path this is etc .... – Olivier_s_j Nov 30 '11 at 13:48
  • when you have problem with paths, you get something like 'library not found', and not 'symbol not found for architecture'. – pronvit Nov 30 '11 at 14:22
