Looks like SSIZE_MAX is usually <*/limits.h>: pd$ grep -r SSIZE_MAX /usr/include/ /usr/include/i386/limits.h:#define SSIZE_MAX LONG_MAX /* max value for a ssize_t */ /usr/include/limits.h:#define _POSIX_SSIZE_MAX 32767 /usr/include/ppc/limits.h:#define SSIZE_MAX LONG_MAX /* max value for a ssize_t */ If R_xlen_t is int, you need to adjust R_XLEN_T_MAX to INT_MAX or so. The case warnings look like they are bound to happen on systems where int and long have the same size, and should presumably be harmless. > Thanks, > > > Jony > > -- > Centre for Cold Matter, The Blackett Laboratory, > Imperial College London, London SW7 2BW > T: +44 (0)207 5947741 > http://www.imperial.ac.uk/people/jony.hudson > http://www.imperial.ac.uk/ccm/research/edm > http://www.monkeycruncher.org > http://j-star.org/ > -- > > On 2 May 2013, at 17:12, Jony Hudson <jony.hud...@imperial.ac.uk> wrote: > >> Hi, >> >> I'm trying to cross-compile R to javascript so that it can run in a >> web-browser.
