Hi Corinna,

Do you happen to have the LD_LIBRARY_PATH environment variable set in your shell? If so, I would unset it. LD_LIBRARY_PATH tends to mess with any programs linked to dynamic libraries. In this case, it’s forcing freeview to load the wrong matlab Qt libraries.

Subject: [Freesurfer] matlab runtime error

        External Email - Use Caution        

Hi all,

I ran a few subjects successfully through7.1.1, but when I got to check the surfs in freeview I get an error about the Matlab runtime libraries below. However, I already have those libraries and the 2014b runtime environment installed on my Ubuntu 18.04.

freeview: /usr/local/MATLAB/MATLAB_Runtime/v97/bin/glnxa64/libQt5X11Extras.so.5: no version information available (required by freeview)
freeview: /usr/local/MATLAB/MATLAB_Runtime/v97/bin/glnxa64/libQt5Core.so.5: no version information available (required by freeview)
freeview: /usr/local/MATLAB/MATLAB_Runtime/v97/bin/glnxa64/libQt5Gui.so.5: no version information available (required by freeview)
freeview: /usr/local/MATLAB/MATLAB_Runtime/v97/bin/glnxa64/libQt5Widgets.so.5: no version information available (required by freeview)
freeview: relocation error: freeview: symbol _ZN17QAbstractItemView11eventFilterEP7QObjectP6QEvent version Qt_5 not defined in file libQt5Widgets.so.5 with link time reference

I also tried re-installing the 2014b MCR, but get this message:

fs_install_mcr R2014b
curl: /usr/local/MATLAB/MATLAB_Runtime/v97/bin/glnxa64/libcurl.so.4: no version information available (required by curl)
curl: (48) An unknown option was passed in to libcurl

Let me know how to best proceed.

Thanks!

Corinna
