Dear all,

I am new to Einstein Toolkit and am having some difficulty installing it. My system is minimal Ubuntu 14.04 ​ with basic build toolchain​ . I followed the instructions given and ran:

curl -kLO

https://raw.githubusercontent.com/gridaphobe/CRL/ET_2014_11/GetComponents chmod a+x GetComponents ./GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2014_11/einsteintoolki... cd Cactus make test

I removed BLAS and LAPACK from Cactus/configs/build/Thornlist because it complains that OpenBLAS does the same thing. Then I ran:

make

​ test​

​The build fails at compiling GRHydro:​

​My Fortran compiler is from Ubuntu:

​# gfortran --version

GNU Fortran (Ubuntu 4.8.2-19ubuntu1) 4.8.2

​Thanks in advance for the help~
