Rgdal windows binary warning message
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.

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?
