[otb-users] OTB Superbuild and QT5

[Daniel McInerney]

Hi List,

I have run the superbuild using the following cmake:

cmake /work/otb/OTB/SuperBuild
-DCMAKE_INSTALL_PREFIX=/work/otb/installdir -DOTB_USE_OPENCV=ON
-DOTB_USE_QT=OFF

However, despite specifying -DOTB_USE_QT=OFF (and -DOTB_USE_QT5=OFF), it
still installs QT5 and the OTB gui applications. Although this doesn't
present an issue for the OTB applications, when I update /etc/ld.so.conf
with the new library path, the QT version installed during the
Superbuild conflicts with the system version. Consequently, when I try
to run qgis (or other QT5 dependent applications), I get the following
issue: 

Cannot mix incompatible Qt library (version 0x50905) with this library
(version 0x50a01)

Aborted (core dumped)

I've followed the documentation here [1] and this tutorial [2], but to
date, I haven't been able to disable QT5 during the installation. Any
advice appreciated.

best regards,

Daniel.

Hi Daniel,

Can you try also setting OTB_USE_QWT=OFF? I think that it enables QT (not very intuitive, I know)

Hi Victor,
Many thanks, that solved it. I was going to suggest to add this to the
documentation, but I see that it is being handled by MR!291.
best regards,
Daniel.
