I use
Ubuntu 18.04
QGIS version: 3.6.2-Noosa
QGIS code revision: 656500e
Qt version: 5.9.5
GDAL version: 2.2.3

An error occurs while executing the algorithm

Error
/home/cnc/.OTB/bin/otbApplicationLauncherCommandLine: error while loading shared libraries: libOTBCommandLine-6.6.so.1: cannot open shared object file: No such file or directory
The file “libOTBCommandLine-6.6.so.1” is in the directory
/usr/lib/x86_64-linux-gnu
and
/home/cnc/.OTB/lib
How to make the program work?

Hello,

In QGIS, have you set the OTB application folder and OTB folder variables to the right folder ? (options/processing/providers/OTB)

Thanks for your help. Yes, I set the paths to the folders.
OTB application folder ---- /home/ cnc/.OTB/lib/otb/applications
OTB folder ---- /home/ cnc/.OTB/

Hi,
Can you check the following things please and post the command output:

  • make sure you do not have any environment variable like LD_LIBRARY_PATH (echo $LD_LIBRARY_PATH)
  • look at where the otbApplicationLauncherCommandLine is looking for its shared library (ldd /home/cnc/.OTB/bin/otbApplicationLauncherCommandLine)

Also can I ask you why you have the shared lib in /usr/lib/x86_64-linux-gnu? Do you know where it comes from?

NB: you can also do a printenv to check if you do not have any other variables coming from old OTB installation that corrupt the correct behavior of otbApplicationLauncherCommandLine.

Hi, Antoine
I installed the program for the first time.
Сommand output:
echo $LD_LIBRARY_PATH
Empty command output

ldd /home/cnc/.OTB/bin/otbApplicationLauncherCommandLine
the output of the command is very large. Here is only one part

Ok, so here you have an installation problem. How did you install OTB? Was there any output when executing the OTB-6.6.0-Linux64.run?

Thanks everyone!
My mistake was to rename the unpacked folder OTB-6.6.1-Linux64 -> OTB
