Error in xbob.paper.tpami2013 related to bob-master version
eslam mostafa
Manuel Günther and laurent El Shafey: Thanks for your help and time for fixing the compile error of giflib version > 5.1 with bob. I used the master version from git hub.
Unfortunately, I had this error with the version of bob.master
Note : while I am running old version of bob 1.2 , I was not have this problem.

If you want to replicate the results of our TPAMI article from 2013, you need to install bob 1.2.x.
The package https://pypi.python.org/pypi/xbob.paper.tpami2013 indeed relies on the API of the bob 1.2 branch. It is hence not compatible with the current master branch of bob (which is the development branch of bob 2.0.x) on github.
First, revert any change that you may have done in "boost/smart_ptr/shared_ptr.hpp and boost/smart_ptr/detail/shared_count.hpp" and make sure you have a clean environment.
You then have two options:
1- Compilation from source
1.a. Download the archive located here:
https://github.com/idiap/bob/releases/tag/v1.2.2
1.b. Installation of the dependencies required by bob 1.2. List available here
http://www.idiap.ch/software/bob/docs/releases/v1.2.2/sphinx/html/Dependencies.html#section-dependencies
1.c. Compilation of bob, according to the instructions here:
http://www.idiap.ch/software/bob/docs/releases/v1.2.2/sphinx/html/Compilation.html
2. If you are using a distribution with a pre-packaged release of bob such as Ubuntu 12.04 LTS or Mac OS X, you could just install bob using your package manager, e.g. on ubuntu (see https://github.com/idiap/bob/wiki/Packages)
$ sudo add-apt-repository ppa:biometrics/bob
$ sudo apt-get update
$ sudo apt-get install bob
Once bob is installed properly, you will have to follow the following instructions to install the package xbob.paper.tpami201:
https://pypi.python.org/pypi/xbob.paper.tpami2013#installation
If you don't succeed in installing bob cleanly, please report us the detailed error message as well as information (such as version) about your operating system and dependencies (giflib and boost). A good way to be helped successfully is to follow these guidelines:

With kind regards,
Laurent

Following your new issue #194 (please use the mailing list for problem wrt. the installation, except if you identify a 'clear' bug).
https://github.com/idiap/bob/issues/194
If you really compiled bob against giflib 4.2.0, I don't see how you could get the error you reported here:
"""
../../../lib64/libbob_io.so: undefined reference to
MakeMapObject'
../../../lib64/libbob_io.so:
undefined reference toFreeMapObject'collect2: error: ld returned 1 exit status
src/io/cxx/CMakeFiles/test_bob_io_image_codec.dir/build.make:102: recipe for target 'bin/test_bob_io_image_codec' failed
make[2]: *** [bin/test_bob_io_image_codec] Error 1
CMakeFiles/Makefile2:765: recipe for target 'src/io/cxx/CMakeFiles/test_bob_io_image_codec.dir/all' failed
"""
In giflib 4.x.y, the following functions should be defined in your giflib header (most probably in /usr/include/gif_lib.h):
"""
267 extern ColorMapObject *MakeMapObject(int ColorCount,
268 const GifColorType * ColorMap);
269 extern void FreeMapObject(ColorMapObject * Object);
270 extern ColorMapObject *UnionColorMap(const ColorMapObject * ColorIn1,
271 const ColorMapObject * ColorIn2,
272 GifPixelType ColorTransIn2[]);
"""
In contrast, in giflib 5.x.y, these functions have been renamed:
"""
extern ColorMapObject *GifMakeMapObject(int ColorCount,
const GifColorType *ColorMap);
extern void GifFreeMapObject(ColorMapObject *Object);
extern ColorMapObject *GifUnionColorMap(const ColorMapObject *ColorIn1,
const ColorMapObject *ColorIn2,
GifPixelType ColorTransIn2[]);
"""
which would explained the undefined references that you faced.
Could you please make sure that giflib 4.x.y is properly installed, and then try to recompile bob again (after a make clean).
I may give a try in compiling bob on the mageia distribution, but this would take some time.
Another option for you would be to use a virtual machine with bob 1.2 preinstalled. You may find such virtualbox images here:
