Hi, Brad, I think the problem is with the “awk” utility. It’s probably something like the tools are running the awk binary from the OS, but it ends up using a shared library from your MATLAB or Xilinx installation (or vice versa) and there is something of a mismatch. I recommend trying to find out which awk binary is being used and then use “ldd /path/to/the/used/awk” to find out which libraries the dynamic linker is using with it.
FWIW, on Ubuntu 12.04 I found that I needed to use the OS version of libstdc++ so I renamed /opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libstdc++.so.6 (to save it as a backup) then recreated it as a symlink to the OS version at /usr/lib/x86_64-linux-gnu/libstdc++.so.6.
