question about Makeconf and nvcc/CUDA
You will need a src/Makevars.win to get a .cu file to compile. It is not a known extension: see ?1.1.4 of 'Writing R Extensions' Most likely you need something like cudasize.dll: nvcc -m32 --shared -o $@ cuda4.cu in Makevars.win. Also, heed the advice about trying R CMD INSTALL before R CMD check.

Now let's try again. I set up the CYGWIN environment command as kindly suggested by Prof. Ripley.
Here are my next steps:
R CMD build cudasize
* checking for file 'cudasize/DESCRIPTION' ... OK
* preparing 'cudasize':
* checking DESCRIPTION meta-information ... OK
* cleaning src

Subdirectory 'src' contains:

These are unlikely file names for src files.
* checking if there is a namespace ... OK
* checking for executable files ... OK
* checking for hidden files and directories ... OK
* checking for portable file names ... OK
* checking whether package 'cudasize' can be installed ... ERROR
Installation failed.
See 'c:/PROGRA~1/R/R-3.0.1/bin/i386/cudasize.Rcheck/00install.out' for details.
And the 00install.out file is:
* installing *source* package 'cudasize' ...
** libs
*** arch - i386
ERROR: compilation failed for package 'cudasize'
* removing 'c:/PROGRA~1/R/R-3.0.1/bin/i386/cudasize.Rcheck/cudasize'
So it doesn't seem that CUDA is working here. However, if I compile cuda4.cu from the command line, it works fine, as seen here:
nvcc -m32 --shared -o cuda4.dll cuda4.cu
nvcc -m32 --shared -o cuda4.dll cuda4.cu
cuda4.cu
tmpxft_000013d4_00000000-5_cuda4.cudafe1.gpu
tmpxft_000013d4_00000000-10_cuda4.cudafe2.gpu
cuda4.cu
tmpxft_000013d4_00000000-5_cuda4.cudafe1.cpp
tmpxft_000013d4_00000000-15_cuda4.ii
So that is my situation.
This is Windows 7, R version 3.0.1
Thanks,
Erin

I would like to put together a package which contains a CUDA program on Windows 7. I believe that it has to do with the Makeconf file in the etc directory.
