# MAKEFILE FOR GNU/Linux SPIDER using FFTW on single processor --
#        Non-native mode byte ordering on AMD/Intel IA32  
#
# Using: Portland Group F90 compiler
#        Non-native mode byte ordering on Intel IA32 GNU/Linux SHOULD RUN ON MOST LINUX PC's
#        FFTW3 must be configured with: --enable-float --enable-type-prefix
#
# Note:    You may ignore any undefined QFFLAGS, QLFLAGS & SUFFIX
#
# Note:  To create executable: make -f Makefile_linux_fftw
