External Email - Use Caution        

Hello Pascale,

Yes, that kind of symbol error has been posted before, and it can from the version of the standard C++ (or C) libraries being too different on the machine the binaries are running on - compared to the machine they were built on.  Generally speaking, newer versions of the OS try to be backwards compatible, e.g., such that binaries built on CentOS 6 could run on CentOS7.  However, forward compatibility may not to work, e.g., CentOS 7 binaries may not run on CentOS 5 or 6.

You could let us know something more about the binaries you are using and the version of the OS you are running on in order to match them up, but using different version of the standard C libraries to run only some binaries is not recommended.

Hello FreeSurfer Developers,

I'm attempting to produce an automated segmentation of the hippocampal substructures and the nuclei of the amygdala (see hippocampal module https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldsAndNucleiOfAmygdala). When I try to run the segmentHA_T1.sh bert  [SUBJECTS_DIR] command with the dev version of freesurfer, I keep getting this error: 
/freesurfer-dev/MCRv84//sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.19' not found 
/freesurfer-dev/MCRv84//sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.19' not found 

It was suggested in the archives that this is a library problem but does anyone have any suggestions on how this can be fixed? 

Thank you in advance,

Pascale
