cuda.eclass
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.
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
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
