It does not work:
jcrn12@jcrn12-VirtualBox:/usr/local/bin$ which freeview
/usr/local/freesurfer/bin/freeview
jcrn12@jcrn12-VirtualBox:/usr/local/bin$ ldd freeview | grep not
ldd: ./freeview: No such file or directory

Sorry - from your previous mail, I mistakenly thought “which freeview” returned /usr/local/bin/freeview.

If you can reproduce what you did before to run freeview from the command line where it tells you that it was not finding libgfortran, then “which freeview” will likely tell you where the binary is.  You should have already set FREESURFER_HOME to point to the freesurfer  installation and then did the source of the shell init file (SetUpFreeSurfer.sh for bash or sh, SetUpFreeSurfer.csh for csh).  See the wiki page here under setup and configuration, https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall  That should have put freeview in your PATH so that “which freeview” works.

What you want to do is to cd into the directory where the freeview binary lives and run ldd on it.  If “which freeview” returned /usr/local/bin/freeview then you could “cd /usr/local/bin” and from there directly run “ldd freeview | grep not”.

That is what happened:
$ ldd /usr/local/bin/freeview | grep not
ldd: /usr/local/bin/freeview: No such file or directory
$ bash
jcrn12@jcrn12-VirtualBox:~$ ldd /usr/local/bin/freeview | grep not
ldd: /usr/local/bin/freeview: No such file or directory

Hello JC,

Try this to see what libs are missing,

$ ldd /usr/local/bin/freeview | grep not

Hi, thank you for your help. 
I tried again and once again it did not work. I am using Ubuntu 18
This is the message I get:

$ freeview
sh: 8: freeview: not found
$  which freeview                  
$ /usr/local/bin/freeview
sh: 10: /usr/local/bin/freeview: not found
$ which ldd
/usr/bin/ldd
$ ldd `which freeview` | grep not
ldd: missing file arguments
Try `ldd --help' for more information.

Thank you very much,
JC.

Hello Juan,

For CentOS try:
$ sudo yum install gcc-gfortran.x86_64
… if that does not work then,
$ sudo yum install libgfortran.x86_64

For Ubuntu,
$sudo apt-get install gfortran

One thing you might want to try first is to run the “ldd” command on the freeview binary to see all/any libraries that are missing....

This should return the path to freeview, e.g., /usr/local/bin/freeview, though your path may differ.
$ which freeview
/usr/local/bin/freeview

- then check you have the ldd command, 
$ which ldd
/usr/bin/ldd

If the above returned paths for freeview and ldd, then run the ldd command followed by the grep command to see what libraries are missing.  Prior to doing the install of libgfortran above, it should list libgfortran is missing.

$ ldd `which freeview` | grep not

Also it would be good to know what linux you are running, e.g., CentOS 7, Ubuntu 18, etc.

Hi, thank you for your answer.
I did what you recommended to me, and I get this message:
freeview: error while loading shared libraries: libgfortran.so.3: cannot open shared object file: No such file or directory.
What could be the next step?

Hello JC,

Your machine could be missing the qt5 libraries/files.

On Ubuntu linux you can try installing them with,
$ sudo apt-get install qt5-default qtcreator libqt5x11extras5-dev

On CentOS linux,
$ sudo yum install qt-create qt-config.x86_64
$ sudo yum install qt5-qtx11extras.x86_64 qt5-qtx11extras-devel...x86_64

Hello, I am trying to use freeview, but everytime I try I get this message:
freeview: error while loading shared libraries: libQt5Widgets.so.5: cannot open shared object file: No such file or directory.
How can I fix it?
Thanks a lot,
