Installation seems to fail

[Richard_O]

Good morning,

I have a bit of a Problem, I am unable to start rtabmap. I followed the instructions on the GitHub-Page for the source installation and all I get from the rtabmap standalone binary is a segmentation fault. Mind you it compiles without any errors and the installation works as expected. Roslaunch on the rtabmap_ros produces more informative feedback: *** Error in `/home/pas/catkin_ws/devel/lib/rtabmap_ros/rtabmap': realloc(): invalid pointer: 0x00007fcd00a6b840 ***

The System is as follows:
OS:
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
Hardware:
Memory 15,6GB
Processor Intel® Core™ i7-3610QE CPU @ 2.30GHz × 8
Graphics Intel® Ivybridge Mobile
OS-Type 64-bit
Disk 235,1 GB
Software:
OpenCV 2.4.11
ROS Indigo

As the problem occurs on four machines I am working on (all are the same model wit the same specifications) I can also provide a complete bash history, the output of the cmake configuration and a list of the installed software acquired with dpkg -l. Frustrating is, that rtabmap is working fine on two older laptops woking with the same OS.

Any help is appreciated.

Thanks in advance,
Richard

Can you try these commands to see if they crash too:

$ ./rtabmap-rgbd_camera
$ ./rtabmap-rgbd_mapping

To get more debug information, you can set "ULogger::setLevel(ULogger::kDebug);" instead of "ULogger::setLevel(ULogger::kInfo);" or "ULogger::setLevel(ULogger::kWarning);" in the binaries:
-For rtabmap, see app/src/main.cpp
-For rtabmap-rgbd_camera, see tools/CameraRGBD/main.cpp
-For rtabmap-rgbd_mapping, see examples/RGBDMapping/main.cpp

Thank you for the pointer, I was able to resolve the issue. The problem seemed to be the installation of qt5-default, along  with qt4, which I used in my build of OpenCV 2.4.11. After the removal of qt5 and recompiling OpenCV, rtabmap and rtabmap_ros it is working!

Best wishes,
Richard
