R help - Feb 2007 - Calling C code from R

Hi!
   
  Thanks in advance.
   
  I am using R-2.4.0 on Windows XP. I am trying to create dll file.
   
  My C code:
   
  /* useC1.c */
  void useC(int *i) {
    i[6] = 100;
}
   
  I have tried to create useC1.dll. 
   
  C:\R-2.4.0\bin>R CMD SHLIB useC1.c
   
  'perl' is not recognized as an internal or external command, operable
program or batch file.
   
  Then I have tried:
   
  C:\R-2.4.0\bin>Rcmd SHLIB useC1.c
   
  'perl' is not recognized as an internal or external command, operable
program or batch file.
   
  I am looking forward for your reply.
   
  Regards,

Did you install Perl? and did you read
http://cran.r-project.org/doc/manuals/R-admin.html#The-Windows-toolset
and http://cran.r-project.org/doc/manuals/R-exts.html#Creating-R-packages?

You need to install perl and MinGW, at least.
If you have them installed, then you need to properly set PATH environment
variable and, probably, restart your command line session.

See chapter 5 of the manual "Writing R extensions" (installed in
R_HOME/doc/manual)
and these two links

http://www.murdoch-sutherland.com/Rtools/
http://www.stats.uwo.ca/faculty/murdoch/software/debuggingR/

Also, it would be great to upgrade R to 2.4.1
