# @ECLASS: cuda.eclass
# @MAINTAINER:
# Justin Lecher <jlec@gentoo.org>
# @BLURB: Common functions for cuda packages
# @DESCRIPTION:
# This eclass contains functions to be used with cuda package. Currently it is
# setting and/or sanitizing NVCCFLAGS, the compiler flags for nvcc. This is
# automatically done and exported in src_prepare() or manually by calling
# cuda_sanatize.
# @EXAMPLE:
# inherit cuda
# @ECLASS-VARIABLE: NVCCFLAGS
# @DESCRIPTION:
# nvcc compiler flags (see nvcc --help), which should be used like
# CFLAGS for c compiler
: ${NVCCFLAGS:=-O2}
# @ECLASS-VARIABLE: CUDA_VERBOSE
# @DESCRIPTION:
# Being verbose during compilation to see underlying commands
: ${CUDA_VERBOSE:=true}
# @FUNCTION: cuda_gccdir
# @USAGE: [-f]
# @RETURN: gcc bindir compatible with current cuda, optionally (-f) prefixed with "--compiler-bindir="
# @DESCRIPTION:
# Helper for determination of the latest gcc bindir supported by
# then current nvidia cuda toolkit.
#
# Example:
# @CODE
# cuda_gccdir -f
# -> --compiler-bindir="/usr/x86_64-pc-linux-gnu/gcc-bin/4.6.3"
# @CODE
cuda_gccdir() {

# Currently we only support the gnu compiler suite

# Call cuda_src_prepare for EAPIs not supporting src_prepare
