Hi, thanks for reporting. I don't know what that error could be caused by. Could you please add the whole output, not only the one line with the error.

If possible, please try rosrun --prefix 'gdb -ex run --args' rgbdslam rgbdslam, then after the crash type backtrace and attach the output here.

from rgbdslam_v2.

roslaunch rgbdslam openni+rgbdslam.launch

return the following:

rgbdslam requires qt4, you have qt5. I don't know why it would build correctly and link against qt5.
Maybe issue #17 has more information?

from rgbdslam_v2.

I deleted qt5.

from rgbdslam_v2.

The error still occurs in /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 (in levels 5 to 9 of the backtrace). Have you cleaned an rebuilt? Try rm -rf ~/rgbdslam_catkin_ws/build/ before catkin_make, to make sure cmake is not caching anything qt5 related.

from rgbdslam_v2.

I completely reinstall ROS but it did't help. Looks like there still some qt5 related packages that participated in the making process (which I could't find). I removed all files from /usr/lib/x86_64-linux-gnu/ with "Qt5" in the name, but it did not help.

Actually my problem is that I'm not that good at Linux, therefore the only things that solved my issue is reinstalling the Ubuntu. rgbdslam fit default ubuntu 14.04 pretty well.

Thanks!

from rgbdslam_v2.

Sorry to hear you had to take the brute force approach (i.e. reinstall).

from rgbdslam_v2.

no problem.
just one more comment: yes, on default Ubuntu I did catkin_make and everything works fine. But after installing all dependencies for OpenCV (qt5-default among them) and OpenCV inself, I have the same error while launching rgbdslam:

Error in `/home/negvet/rgbdslam_catkin_ws/devel/lib/rgbdslam/rgbdslam': realloc(): invalid pointer: 0x00007f9fc000a840

looks like I just need to configure rgbdslam to not to use everything related to qt5 while starting up, but I do not know how..

from rgbdslam_v2.

Please check whether you built against the right version. ldd /path/to/your/executable/rgbdslam should turn up something like

(...)
libQtCore.so.4 => /usr/lib/x86_64-linux-gnu/libQtCore.so.4
(...)

If there is a 5 instead of 4 you can try the following: Check out the exact qt 4 version with /usr/bin/qmake-qt4 -v. For me this prints Using Qt version 4.8.6.

Then state the version exactly in the CMakeLists.txt of rgbdslam by changing the line

find_package(Qt4 REQUIRED)

to reflect the exact version, e.g.,

find_package(Qt4 4.8.6 EXACT REQUIRED)

from rgbdslam_v2.

So here are both 4 and 5.
/usr/bin/qmake-qt4 -v returns

QMake version 2.01a
Using Qt version 4.8.6 in /usr/lib/x86_64-linux-gnu

So I updated CMakeLists.txt with
find_package(Qt4 4.8.6 EXACT REQUIRED)

Then I run catkin_make clean , rm -rf ~/rgbdslam_catkin_ws/build/, catkin_make but finally I have the same error:
`Error in /home/negvet/rgbdslam_catkin_ws/devel/lib/rgbdslam/rgbdslam': realloc(): invalid pointer: 0x00007f51a375a840``

from rgbdslam_v2.

Hm, weird. Maybe another library is pulling in qt5? I'm out of ideas how to solve this, sorry.
