Hello Raman,

thank you very much,
I just tempted to set LD_LIBRARY_PATH

(but without success) using export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:${LD_LIBRARY_PATH}

07:30:12 $ export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:${LD_LIBRARY_PATH}
07:30:32 $ pwd
/home/gcaddeo/openDTect/git/installation/bin/lux64
07:30:38 $ cd Debug/
07:30:42 $ ./od_ma
od_madexec  od_main    
07:30:42 $ ./od_main
Segmentation fault (core dumped)
07:30:48 $ cd ../Release/
07:30:57 $ ./od_main
Segmentation fault (core dumped)


I'm using an UBUNTU MACHINE (Linux milcham 3.19.0-58-generic #64~14.04.1-Ubuntu SMP Fri Mar 18 19:05:43 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux) in which I installed qt4 and qt5 packages from apt-get.

this is my dirs tree:
 07:27:51 $ sudo find /usr -name "libQtGui*"
/usr/lib/i386-linux-gnu/libQtGui.so.4.8
/usr/lib/i386-linux-gnu/libQtGui.so.4
/usr/lib/i386-linux-gnu/libQtGui.so.4.8.6
/usr/lib/x86_64-linux-gnu/libQtGui.so.4.8
/usr/lib/x86_64-linux-gnu/libQtGui.so.4
/usr/lib/x86_64-linux-gnu/libQtGui.so.4.8.6
07:27:52 $
07:27:52 $ sudo find /usr -name "libQt5*" | grep Gui
17:/usr/lib/x86_64-linux-gnu/libQt5Gui.so.5
25:/usr/lib/x86_64-linux-gnu/libQt5Gui.so
32:/usr/lib/x86_64-linux-gnu/libQt5Gui.so.5.2
48:/usr/lib/x86_64-linux-gnu/libQt5Gui.so.5.2.1
102:/usr/lib/x86_64-linux-gnu/libQt5Gui.prl

I also used qtchooser tool to switch between libraries, but nothing...
qtchooser --print-env
QT_SELECT="default"
QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt5/bin"
QTLIBDIR="/usr/lib/x86_64-linux-gnu"

I attach also my cmake configuration for qt (Today I have a doubt for /usr/lib/libosgQt.so and I will re-check it)

Thank you so much

Best regards

Hi Gianluigi,

I think that problem is cause by fact that I compiled opendtect with qt5, but, at run, opendtect looks for libQtGui.so.4 instead libQt5Gui,
How to do?  I need to use libQt5 but my efforts did not give results...

In the terminal where you run OpendTect, set the environment variable LD_LIBRARY_PATH to use Qt5 libraries. For example,

setenv LD_LIBRARY_PATH /usr/local/qt5/lib:${LD_LIBRARY_PATH}

I hope this helps.

Regards,

Raman K Singh

Dear all,
I Installed opendtect by OpendTect_Installer_lux64.sh script and everything goes well.
I performed, also, a second installation by sources that download by from https://github.com/OpendTect/OpendTect.git.
I compiled and installed opendtect in debug mode (CMAKE_BUILD_TYPE=Debug)
My problem is that when I run start_dtect -> /home/opendTect/git/installation/bin/start_dtect* from my command line
I have a segmentation fault:
/start_dtect
Setting up GMT environment ... GMT installation directory not found
Setting up Madagascar environment ... Madagascar installation directory not found
Segmentation fault (core dumped)
I do not know if this could be useful, but If I launch the script in debug mode, (I understand that it is need to set export DTECT_START_DEBUGGER=/usr/bin/gdb, but I'm not sure)
output is:
17:14:09 $ ./start_dtect

Setting up Madagascar environment ... Madagascar installation directory not found

Did you have some idea about the problem?
