Optional features

You can enable optional features by setting the following variables to 1 before compilation:

• OWL_ENABLE_EXPMODE=1: turn on experiment features like -flto

• OWL_ENABLE_DEVMODE=1: turn on all the warnings in development

• OWL_ENABLE_OPENMP=1: turn on OpenMP support in core module and the automatic parameter tuning (AEOS)

• OWL_CFLAGS allows to change the default flags passed to the C targets, it defaults to

  OWL_CFLAGS="-g -O3 -Ofast -march=native -mfpmath=sse -funroll-loops -ffast-math -DSFMT_MEXP=19937 -msse2 -fno-strict-aliasing -Wno-tautological-constant-out-of-range-compare"`
  

• OWL_AEOS_CFLAGS allows to change the default flags passed to the C targets when compiling AEOS. It defaults to

  OWL_AEOS_CFLAGS="-g -O3 -Ofast -march=native -funroll-loops -ffast-math -DSFMT_MEXP=19937 -fno-strict-aliasing"
  

If you are not using opam, you should run make clean before recompiling the library after having changed any of those environment variables.
