# Assumes ifort and icc are installed. Run this script to compile both intel fftw2, fftw3 libraries.

# Important: must run this code as root, or it may not find the correct links, e.g., -liomp5
# In case it does not sucess, try to yum install compat-libstdc++-33.x86_64
# It may also not able to install if it can't find icc in the path. In that case, do the folloing:
# cd /usr/bin
# ln -s /opt/intel/Compiler/11.0/081/bin/intel64/icc /usr/bin/.
# Then rerun this script again.
