Hi,
I would like to introduce a new eclass for packages using the nvidia
cuda compiler suite. Currently the eclass simply sanitize the NVCCFLAGS.
May be extended in the future.
Two problems come up with using nvcc:
* Each version only supports a limited number of gcc versions. Therefore
we need to pass the path to a supported gcc bindir
* nvcc calls CXX but doesn't pass CXXFLAGS on.
I don't know if this is helpful feedback, but it would be great if our
"CUDA" compiler was also detected in your eclass.
Notable differences : Probably a lot faster compilation times (needs
benchmarking), no external userland dependencies (gcc or nvidia), we
don't support nvcc flags and we have a driver just for the CUDA language
Example:
pathcu deadbeef.cu
./a.out
(Unfortunately our recent nightly builds started to do a license check,
but any interested open source dev just ping me to get setup)
To validate simple things you could use an older nightly
http://c591116.r16.cf2.rackcdn.com/enzo/nightly/Linux/enzo-2012-11-18-installer.run
chmod +x enzo-2012-11-18-installer.run ; ./enzo-2012-11-18-installer.run
--mode unattended # --prefix /opt/foobar
./C
