[R-SIG-Mac] compiling from source on ML, tcltk

[Kasper Daniel Hansen]

I now want to get tcltk support working under ML (because I need to
test a few packages).

I have installed Xquartz and I have just install the new tcltk 8.5.5
from CRAN (which is not signed btw).

Running configure, I get

checking for tclConfig.sh... no
checking for tclConfig.sh in library (sub)directories...
/usr/local/lib/tclConfig.sh
checking for tkConfig.sh... no
checking for tkConfig.sh in library (sub)directories...

checking /usr/local/include/tk.h presence... no
checking for /usr/local/include/tk.h... no
checking for tk.h... yes

So it seems to find tcltk.  I get a few warnings when it checks for X11 headers:

checking X11/Intrinsic.h presence... no
configure: WARNING: X11/Intrinsic.h: accepted by the compiler,
rejected by the preprocessor!
configure: WARNING: X11/Intrinsic.h: proceeding with the compiler's result

and

checking X11/Xmu/Atoms.h presence... no
configure: WARNING: X11/Xmu/Atoms.h: accepted by the compiler,
rejected by the preprocessor!
configure: WARNING: X11/Xmu/Atoms.h: proceeding with the compiler's result

I assume these are unrelated.  Although configure seems to find tcltk,
at the end of configure, I get

R is now configured for x86_64-apple-darwin12.1.0

  Source directory:          ../R-2.15.x-src

  Options enabled:           R profiling, memory profiling, Java

  Recommended packages:      yes

which does not mention tcltk support under 'Interfaces supported'.

This used to work on Lion, and I am wondering what I am doing wrong.

My configure script is

export LANG=en_US.UTF-8
../${SRCDIR}/configure SHELL='/bin/bash' \
  --prefix=/usr/local/R/R-${R_VERSION} --disable-R-framework\
  CC="/usr/bin/gcc-4.2 -arch x86_64 -std=gnu99" \
