R help - Feb 2005 - Compilation of R (linux) package on windows

Hello,
I develop some R package on Linux machine with C subroutines.
The programs in C are well compiled on Linux machine and so I have some
".so"
files.

Now, I want to do the same work on windows, so I install R (the last version) 
on windows, with Active Perl and djgpp, which is, as I know, the gcc version 
for windows (to compile C program), but unfortunately when I run "R CMD
SHLIB
inv.c, ", I have an error.
I think it's a problem with my choice of compiler C, could somebody give to
me
the name of good compiler to do that ?

Please read the R for Windows FAQ 3.1 "Can I install packages into 
libraries in this version?".
It points you to README.packages, 
http://www.murdoch-sutherland.com/Rtools/ , and tells you "Note that 
this is rather tricky; please do ensure that you have followed the 
instructions exactly."

Confusion is the price you pay for not following the directions given.  You
need to download and install the  tools in Rtools.zip as mentioned in
README.packages, and have it the the appropriate position in the PATH, as
also mentioned in README.packages.
