HI, I'm setting up freeview on a Linux 18.04 system and running through the instructions in https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall

I got through to Example 4: "View the output volumes..." and got the error below.

harritp1@TPHTVB:~/FSSubjects$ freeview freeview.bin: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory

It looks like I need to either set up an environment variable, or install that specific graphics library. I did an install of the latest version of libpng: i. e. sudo apt-get install -y libpng-dev but that didn't fix the problem.

Have you dealt with this?

Thanks Tim
