Dear @mzaiady,

Thanks for your kind request.
Despite many careful reads and a lot of effort I couldn't figure out your operating system, compiler, compiling options, or installed libraries.
Even worst, I couldn't find any question in your message.

This sadly prevents me to help you, and I'm sorry to inform you that I'm closing this issue, as you failed to comply to basic rules of courtesy.

Best wishes,

N.

Thank you for replay, sorry for missing information!

Installation and build works fine, but I’m getting the error while running the ./run-example.sh
I'm planning to use it for within ROS, PCL 1.7

Current configuration:

OS: Ubuntu 14.0.4

from CMakeCache.txt

OpenCV_3RDPARTY_LIB_DIR_DBG:PATH=/opt/ros/indigo/share/OpenCV-3.1.0-dev/3rdparty/lib
OpenCV_3RDPARTY_LIB_DIR_OPT:PATH=/opt/ros/indigo/share/OpenCV-3.1.0-dev/3rdparty/lib
OpenCV_CONFIG_PATH:FILEPATH=/opt/ros/indigo/share/OpenCV-3.1.0-dev
OpenCV_DIR:PATH=/opt/ros/indigo/share/OpenCV-3.1.0-dev

Hi,

Thanks for the report.

So, if I'm right, OpenCV libraries are not included in your path, right ?
One fix would be to add the OpenCV library path to the applications RPATH.

I can try to push a tentative fix tomorrow. In the meantime, adding OpenCV libraries either in your system library dir, or in Super4PCS lib folder should temporarly fix the problem.

Cheers

Hi,

I've pushed a candidate fix in #51 .
Could you please checkout branch fix_rpath_from_master and check if solves your problem ?

Thanks

Example Works Fins now, thank you very much!

when trying to add this my my project

set(Super4PCS_DIR "usr/share/code/Super4PCS/build/install/lib/cmake")

I'm getting the following error:

Imported target "super4pcs_algo" includes non-existent path

"/usr/include/opencv-3.1.0-dev/opencv"

Additional query, maybe should open another issue! I have PCL 1.7 Would PCLWrapper work with it!
