package/fftw/ that already exists in Buildroot builds the exact same
source code. Why do you think a different package is needed?
Why don't you just add the:
+ifeq ($(BR2_ARM_ENABLE_NEON),y)
+FFTWF_CONF_OPT = --enable-single --enable-neon
+FFTWF_CONF_ENV += \
+ CFLAGS="$(TARGET_CFLAGS) -mfpu=neon -mfloat-abi=softfp"
+else
+FFTWF_CONF_OPT = --enable-single
+endif
block of code into package/fftw/fftw.mk ?
In Buildroot, we generally have one package for each source tarball.
But this package may provide different configuration options to adapt
to the specificities of the platform, or to provide different kind of
features.
Best regards,
Thomas
