Hi Henry,
The issue appears to be that your version of GCC is too old to compile
the kernels which are generated by PyFR. As per the user guide PyFR
requires GCC 4.9 or newer (alternatively, a recent version of the Intel
compiler may also be used).
Regards, Freddie.

Dear all,
I am new to PyFR and have installed it these days. I d like to run the
first tutorial with -b openmp but I received the following error. I am
quite confused about it. By the way, I installed openblas in anaconda
and the python version is 3.6 as well as the ubuntu version is 12.04.5
LTS. Could anyone help me out?
Thank you all in advance!
