[R] cross building

[Jun Yan]

I was trying to learn cross building an R pcakage for windows on my linux
machine. I picked a relatively small library gee to test. I downloaded the
cross-tools and put them in my path,
 
jyan at ludwig:/a3/jyan/src/R-1.2.1/src/gnuwin32$ echo $PATH
/home/jyan/cross-tools/bin:/home/jyan/cross-tools/i386-mingw32msvc/bin:
/usr/lib:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games

Following the instructions, I was able to go through the following:

jyan at ludwig:/a3/jyan/src/R-1.2.1/src/gnuwin32$ make PKGDIR=/home/jyan
RLIB=/home/jyan/Rwinlibs STAMP=NO pkg-gee

Then I zipped the package and installed it on a Win98 machine. But when I
load the library, I got an error message:

>library(gee)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library 
"C:/PROGRA~1/RWIN/RW1021/library/gee/libs/gee.dll":
  LoadLibrary failure:  A device attached to the system is not
functioning.
Error in library(gee) : .First.lib failed

What's the device not functioning? Was my cross-building missing
something? Thanks.
