R help - Dec 2010 - tcltk error compiling R 2.13.0 under Windows 7 x64

Hi All,

I am trying to compile R 2.13.0 r53834 on 64-bit Windows 7 (home
premium) using Rtools212.exe from Duncan Murdoch's site.  I (think) I
followed the installation guide for Windows.  When installing Rtools,
made sure I was installing 64-bit tools (including tcltk), etc.  I
created a copy of MkRules.local where I selected 64 bit instead of 32
architecture.  When I run:

C:\R\R-devel\src\gnuwin32> make all recommended

I get the following error at the very end:

building package 'tcltk'
making init.d from init.c
making tcltk.d from tcltk.c
making tcltk_win.d from tcltk_win.c
x86_64-w64-mingw32-gcc -I"../../../../include" -I
"../../../../Tcl"/include -DWi
n32         -O2 -Wall  -std=gnu99 -c init.c -o init.o
In file included from init.c:22:0:
tcltk.h:23:17: fatal error: tcl.h: No such file or directory
compilation terminated.
make[4]: *** [init.o] Error 1
make[3]: *** [mksrc-win2] Error 1
make[2]: *** [all] Error 2
make[1]: *** [R] Error 1
make: *** [all] Error 2


which seems suggestive that I did not install tcltk or it is looking
for it in the wrong location.  Is there an environment variable I need
to set or should I add something to my PATH?  Rtools created a
directory C:\R64\Tcl

which includes a tcl.h file, so I think that is what I need, I am just
not sure how to tell the compiler where to find it.  Everything else
works like a charm.  Any tips or pointers where to start would be
appreciated.  My sincerest apologies if I missed something from the
installation manual or one of the readmes for Rtools.

Thanks,

Josh

Just in case no one knowledgeable answers, here's my shot in the dark
(I'm mostly a linux user)... the compiler is looking for .h files in
the directories listed in the --I options to gcc, which seems to be
Tcl, not Tcl64. The compiler also defines a macro Win32 which to my
untrained eyes seems suspicious since you are trying to produce a
64-bit executable, right (although perhaps Win32 also applies to
64-bit version, I'm not sure)? Maybe your selection of 64 bit
architecture wasn't honored - is the compiler reading the modified
copy or the original of MkRules?
