Rgdal windows binary warning message

Hello every one--

My sincere apologies if I have missed something obvious, but I need
to construct some multinomial logit models.  I remember using nnet
for this in the past, but I am having trouble locating a OS X version
of this (it's been a year or so since I had to use it). I found a
Windows version, but when I try to install across platforms, it
crashes R immediately--no error messages or anything helpful.  Can
any one direct me to a repository, or alternatively, to another
package readily available Mac side that can do simple multinomial
logit models? This is basic survey data--nothing fancy needed.

All best,

Lisa

Hi all,

I just downloaded windows binaries of RGDAL (from
http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.1/) and installed.

I ran the example R_HOME\library\rgdal\R-ex\getPixmapGDAL.R and everything
seemed to work as expected. However I got the following warning message:

DLL attempted to change FPU control word from 8001f to 9001f

The R-help (?dyn.load) describes the problem as:

************************************
External code must not change the floating point control word, but
    many DLLs do so.  Common changes are to set it to use 53 bit
    precision instead of R's default 64 bit precision, or to unmask
    some exceptions.  'dyn.load' detects such changes,  and restores
    R's control word to its default value of hex 8001F.   This may
    cause the DLL to malfunction; if so, it should be rewritten to
    save and restore the control word itself.  If 'warn.FPU' is set to
    'TRUE' using the 'options' function,  a warning will be printed.
    (If the warning says that the control word was changed from some
    other value than 8001F,  please report the circumstances to the
    Windows maintainers:   that probably indicates an internal bug.)

************************************

Does anyone know if this is a major problem for reading and manipulating
image files using RDAL? And if so are there windows binaries which have
patched it up?

Thanks in advance

Tony

This is a consequence of how VC++ compiled gdal.  R is protecting 
itself against that.  Since R did not crash, there is nothing to worry 
about.
