Hello,
I've held off very long to replace my Powerbook G4 (until it died
about a month ago, actually, 6 years old), and as such I've gotten
into the habit of building R mysel, tweaking it to use the "optimal"
compiler options and the best compiler available to me.
Two questions inspired by that experience:
1) why build the binary distribution such that the compilers
registered in etc/Makeconf are the "system default compiler" wrappers?
Wouldn't it be better to hardcode gcc-4.2 (presuming that's the one
used), to be more robust against users (or Apple!) who redefine the
default compiler version?
2) In R 2.8 (the last version I built), I'd managed to have the tcltk
package available both for X11 and for Aqua, without particular
problems. A simple recompile of the tcltk package pointing to the Tcl
and Tk frameworks instead of the X11 distributions was enough (plus a
very small patch of the code, IIRC). A bit of extra code in the R
launcher script symlinked tcltk.so to the Aqua version if $DISPLAY was
undefined or empty, and to the X11 version otherwise. Needless to say
that having an Aqua Tk interface when running the R GUI has advantages
if not only
I tried the same thing yesterday, after installing the Cocoa version
of Tk (tk-8.5.9-decarbon), without success. tcltk.so builds and loads,
but the GUI version hangs afterwards, in the CLI version I get
##> library(tcltk)

The hang in the GUI occurs as soon as I type an opening brace ((),
suggesting something equivalent to the libreadline rl_event_hook is
not pointing in the right direction.
Before I start chasing ghosts - is there any reason why it would be
impossible to use the Aqua/Cocoa version of Tcl/Tk?
thanks,
René Bertin
