Using bob in Xcode

[Ghifari Rahadian]

I am new to programming so please don't be harsh.

I want to use bob on Xcode. I already install it on my OSX by using this (https://github.com/idiap/bob/wiki/Binary-Installation) via MacPorts.

From this (https://www.idiap.ch/software/bob/docs/releases/last/sphinx/html/IntroCxxDevelopment.html) it is said that I only need to put (#include <io/Video.h>) in my Xcode project. However, My Xcode can not detect the library.

Do I miss something? When I try to use OpenCV in Xcode, I need to set the linker flags manually. Perhaps I need to do so in Xcode as well?

Thank you,

Ghifari

Dear Ghifari,

the documentation you are pointing at is from the old Bob 1.x code, which is not valid for Bob 2 any more.

@idiapers: Guys, do you think we should remove this documentation, or at least add a note to it stating that this documentation is outdated?

indeed, using the C++ interface of Bob is not as straightforward, and there are only few people that have tried to use the pure C++ interface so far. Indeed, by now you have to add compiler and linker options in your CMakeLists.txt on your own. Maybe the discussion in here:

https://groups.google.com/forum/#!searchin/bob-devel/gabor/bob-devel/vSZk5SQ3I9U/MTUDsHUBQh0J

helps. Personally, I have never used Xcode (in fact I don't even know, what that is), so I cannot help you out on that.

Please note that the C++ interface has changed between Bob 1 and Bob 2. For some packages (such as the bob.io.video package), we don't even provide the C++ interface any more (though it should not be difficult to create one, if we would really require that).

@idiapers: It might be a good idea to provide some CMake macros in order to find Bob's libraries and include options, similar to what FindOpenCV.cmake would to for OpenCV: http://code.opencv.org/attachments/196/FindOpenCV.cmake 

In our case this might be a bit more complicated as we would need to get all the dependencies, too. I am already doing that inside python: https://github.com/bioidiap/bob.extension/blob/master/bob/extension/__init__.py#L173

but we would probably need to translate that into CMake syntax.

Best regards

Dear Manuel,

Thank you for your reply. Okay, I guess I have to use another C++ library for my project because converting it to python is already too late
