fftw: fix build failure with old gcc

2015-04-11T13:21:31+00:00

-Ofast is not available on gcc <4.6. This option is equivalent to -O3 -ffast-math.

package/fftw: enable OpenMP if the compiler has that

2015-03-16T18:44:02+00:00

Unfortunately, this is limited to internal toolchains; we currently have no way to know if an external toolchain has support for OpenMP. Signed-off-by: "Yann E.

package/fftw: disable fortran

2015-03-16T18:44:02+00:00

We do not have any fortran package and we do not build a fortran compiler. Still, an external toolchain may have a fortran compiler and that is totally useless to us, since we anyway have no fortran package... So, entirely disable fortran support; that will at least slightly speed up the build in case an external toolchain has a fortran compiler. Signed-off-by: "Yann E.

Use FFTW_CFLAGS as intermediate variable, since we're going to need it in a later patch (about NEON optimisations). Signed-off-by: "Yann E.

fftw: add compile precision option

2015-03-16T18:44:02+00:00

fftw has options to select compile precision between single, long-double and quad. These options are exclusives. This patch adds choice to select precision option.
