Dear R-Helpers,

I am working with Windows XP.
I am trying to build R 2.0.1 from source (R-2.0.1.tar.gz downloaded from 
CRAN).
I read the R Installation and Administration manual and the 
README.packages file as well (probably tot carefully enough !).

I installed the recommended tools and software including TCL/TK software 
(from archive ActiveTcl8.4.9.0.121397-win32-ix86.exe). I modified the 
PATH system variable and created new user variables:

TCLTK_CPPFLAGS=C:\tcl\include
TCLTK_LIBS=C:\tcl\lib

I think these are the problem.  In Windows you should only need to
edit the MkRules file to change these lines:

# Where does Tcl/Tk live? Spaces allowed.
TCL_HOME = $(RHOME)/Tcl
TCL_VERSION = 84

The section I think you were reading where you found TCLTK_CPPFLAGS
was specific to using the configure utility in Unix.
