Discussion:
[otb-users] Ubuntu 18.04 and undefined symbol

Hello.
I have Ubuntu 18.04 installed and added OTB and Monteverdi through the
Synaptic package manager.
When I try to run Monteverdi or otbcli I get the following error and the
software fails to run:

monteverdi: symbol lookup error:
/usr/lib/x86_64-linux-gnu/libotbossimplugins-6.4.so.1: undefined symbol:
_ZN16ossimSensorModel12getObsCovMatERK8ossimDptRN6NEWMAT15SymmetricMatrixEd

or

/usr/bin/otbApplicationLauncherCommandLine: symbol lookup error:
/usr/lib/x86_64-linux-gnu/libotbossimplugins-6.4.so.1: undefined symbol:
_ZN16ossimSensorModel12getObsCovMatERK8ossimDptRN6NEWMAT15SymmetricMatrixEd


This seems to be a known issue
(https://bugs.launchpad.net/ubuntu/+source/otb/+bug/1762378) but I was just
wondering whether a fix for this is imminent, or if I should install from
the project download page to fix it
(https://www.orfeo-toolbox.org/download/)? Or if I should move to a virtual
machine running an older version of Ubuntu whilst the devs look at this bug?

Any pointers would be great
Thanks
Al

Hi all,

I am now rebuilding the OTB package in UbuntuGIS experimental ppa and once
I confirm it is working, I will move it to UbuntuGIS Unstable.

Best,
Angelos
That's great, thank you Angelos!
Hi all,
I will try to fix the issue in the UbuntuGIS repository in the following
days.
Best,
Angelos
Uninstalling the repository version and installing through the download
page (https://www.orfeo-toolbox.org/download/) seems to have fixed that
particular problem.
