In the coming days, I plan to move my code on R-forge, so people can easily
contribute. If you are interested please let me know.

As this header is not listed in R-exts.pdf section 6.17, I think I cannot
use the do_docall function.
Does anyone face this problem? or have an idea on how to solve it?

Hi,
By default, R CMD build makes sources, you have to use --binary if you want to
get binaries. But you have to submit sources to the CRAN ftp server (and not
binary). So just run a R CMD build.

Hi,
You are completely right, the problem was not about what R_alloc
returned but my use of the fill_array32. Now it works fine, but the
block generation is longer due to a conversion to double after using
fill_array32. I must underline the fact that I do not yet use sse2
support.
Thank
Thanks for your remarks.
According to
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/SFMT/howto-compile.html, I
need 16 bit aligned memory when using fill_array64. So I suppose I need 8
bit aligned memory. I will test what you advise me and will come back to
R-devel list after.
Thanks again

Hi,
If you want I can put RANARRAY in the 'randtoolbox' package? unless
you want in R and not in a package?
In randtoolbox (not the version on cran), I port SFMT and WELL

idea to add Knuth's code?

You confirm what I fear, it is not easily possible to test for SSE2
