Hi,

I was having the same problem as described here: https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2017-March/050544.htm... when I was trying to run selxavg3-sess.

I realize that this error was mentioned in the release notes and that the potential fix was sourcing freesurfer and then typing "sudo -E fs_update” into terminal. fs_update seemed to run without any problems, but did not fix the lazy symbol binding error. I did end up fixing the problem after many hours. My fix: I went to http://hpc.sourceforge.net/, downloaded gcc-7.1-bin.tar.gz and followed the instructions on the webpage. I found this error and solution described for another software package here: https://www.ncl.ucar.edu/Download/macosx.shtml#InstallCompilers. I wish I understood compilers enough to figure out exactly what is going on, but I only know that this fixed my error.

I subscribe to the freesurfer emails, but don’t think I am able to add to an old thread or anything so wanted to contact you two directly. I am hoping you could add this to the original thread or the release notes so that others can use this if fs_update does not work for them either.

Best, Alissa
