Compile error on RGBD modul (opencv_contrib)

[albenoit]

Hi,
i report compile error on modules/rgbd/samples/odometry_evaluation.cpp
at line 38 and following

Here is a description :

these 3 include lines generate compile error
instead of

#include <opencv2/rgbd/rgbd.hpp>

i guess it should be

#include <opencv2/rgbd.hpp>

same remark for highgui and contrib includes

I have the following compilation error:

[ 80%] Built target opencv_rgbd

[ 80%] Building CXX object modules/rgbd/CMakeFiles/example_rgbd_odometry_evaluation.dir/samples/odometry_evaluation.cpp.o

make1: [modules/rgbd/CMakeFiles/example_rgbd_odometry_evaluation.dir/all] Erreur 2
make: ** [all] Erreur 2

After correcting includes, i got this compile error
This must be related to missing opencv_XXX libraries links :

@vrabaud, could you please have a look?

[vrabaud]

on it. Thx for giving me rights. Doesn't contrib get sent to the built farm ?
Also, I guess you are using clang right ? I only tested it on Linux GCC 4.8.1.

[vrabaud]

Thx guys, I had indeed not tried to build the sample. Please let me know if that should be closed (lgtm)

Hi Vincent,
I just synced the new code and now it compiles fine. However, i did not
pushed furfer testing.
thanks for your quick reply.

Hi, this code was used quite a lot by Ilya, Maria and I. I still use it in production: just to say that the quality is better than average. If you have any suggestion, please let me know. We hope to have a GSOC to help develop it. I could maybe add a sample with real-time plane tracking (I have it somewhere else).
Should I close the bug or wait for it to be compiled elsewhere ?

Hi,
apprently the build farm does not already manage the opencv_contrib module,
then, i cannot tell you more. Maybe people from Itseez can give more
answers ;o)
Anycase, it works on my plateform so it is fine for me, on a fresh install
so you can think that it will work on similar plateforms.
thanks
Alex
