I'm making a port of http://netlib.org/math/ The supplied makefile has: # This makefile uses features of GNU Make. Uses bash on Linux. # Meant to be run from the directory containing the math77 Fortran directory. # You may need to change the first line above, and the definitions of FC, # std_flags, and FFLAGS below. If code is to be used in production, # you will want to change the optimization level. (For example change # -ggdb to -O3 or -O2. FC = /usr/bin/gfortran std_flags=-march=native -fimplicit-none -fno-f2c -fno-backslash\ -funroll-loops -ffpe-trap=zero,overflow,invalid -finit-real=NAN\ -ftree-vectorize -floop-interchange -floop-strip-mine -floop-block -pipe FFLAGS = -ggdb $(std_flags) -Wall Trying to build (with gfortran48 to gfortran6) I get: f951: sorry, unimplemented: Graphite loop optimizations cannot be used (ISL is not available)(-fgraphite, -fgraphite-identity, -floop-block, -floop-interchange, -floop-strip-mine, -floop-parallelize-all, -floop-unroll-and-jam, and -ftree-loop-linear) Are these not implemented on BSD? I wonder how they build with GCC with these flags? Anyway, should I leave all these flags, and -ggdb in the port? Or should I use the default ports tree FFLAGS instead? Thanks Anton
