[ Image CVSweb ] [ Image Homepage ] [ Image RSS ] [ Image Required by ] [ Image Add to tracker ]

Branch: CURRENT, Version: 0.76, Package name: djbfft-0.76, Maintainer: schmonz

djbfft is an extremely fast library for floating-point convolution.
The current version holds most of the speed records for double-precision
FFTs on general-purpose computers.

djbfft provides power-of-2 complex FFTs, real FFTs at twice the
speed, and fast multiplication of complex arrays. Single precision
and double precision are equally supported.

djbware: reduce lint, mostly by replacing SUBST_CLASSES+=djberrno with
DJB_ERRNO_FIXUP.

While here, sprinkle FORCE_C_STD (mostly c89) where it doesn't break the
build. Tested on NetBSD and macOS.

Log message:
Retire 'djbware-errno-hack' and associated options.mk cleverness.
Instead:

1. Package makefiles including their own options.mk
2. Packages say "SUBST_CLASSES+=djberrno" to get the hack, if needed
3. Packages adjust SUBST_FILES.djberrno, if needed

Should fix bulk build failures due to multiple inclusions of options.mk
and/or incorrect definitions of DJB_ERRNO_HACK.
