NAME

cuda.eclass - 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_sanitize.

SUPPORTED EAPIS

7 8

EXAMPLE

inherit cuda

FUNCTIONS

cuda_gccdir [-f]

Helper for determination of the latest gcc bindir supported by then current nvidia cuda toolkit.

Example:

cuda_gccdir -f
-> --compiler-bindir "/usr/x86_64-pc-linux-gnu/gcc-bin/4.6.3"

Return value: gcc bindir compatible with current cuda, optionally (-f) prefixed with "--compiler-bindir "

cuda_sanitize

Correct NVCCFLAGS by adding the necessary reference to gcc bindir and passing CXXFLAGS to underlying compiler without disturbing nvcc.

cuda_add_sandbox [-w]

Add nvidia dev nodes to the sandbox predict list. with -w, add to the sandbox write list.

cuda_toolkit_version

echo the installed version of dev-util/nvidia-cuda-toolkit

cuda_cudnn_version

echo the installed version of dev-libs/cudnn

cuda_src_prepare

Sanitise and export NVCCFLAGS by default

ECLASS VARIABLES

NVCCFLAGS ?= -O2: nvcc compiler flags (see nvcc --help), which should be used like CFLAGS for c compiler
CUDA_VERBOSE ?= true: Being verbose during compilation to see underlying commands
