Hi Tsu-Chien,

Has anyone tried to use Tcl/tk 8.4a4 with G.I.FEFFit?

Yes. G.I.FEFFIT works on MacOS X. Installing the python package from Fink and then building and installing the Ifeffit-python wrapper will install G.I.FEFFIT.

What I mean is Tcl/Tk for MacOS X. Just found this interesting page: http://www.oreillynet.com/pub/a/mac/2001/10/26/tcl_osx.html?page=4

Ah, sorry I misunderstood. I have not tried to build the Tcl/Tk wrapper on MacOS X, but I'm pretty sure it would be possible and fairly easy. In fact, Tcl/Tk is available from Fink, and installing the python module must also install this, since python/Tkinter uses Tcl/Tk. Right now, the Ifeffit build on MacOS X does not try to build the Tcl extension, but it would be easy to add this. I believe it could be as easy as this: create TclSetup.in in ../wrappers/tcl: #---- LIB_PLT = -L/sw -lpgplot -L/usr/lib -lX11 -lpng LIB_F77 = -lg2c -lm LIB_IFF = -L../../src/macosx -lifeffit INC_IFF = -I../../src/lib CC = gcc CFLAGS = -g -O2 LDFLAGS = #----- and type 'sh Build'. I believe that 'tclsh test.tcl' will then work, running a simple test that doesn't do much besides prove that ifeffit runs from Tcl. I do not know much about how 'packages' are properly installed with Tcl/Tk, and haven't been very good about keeping the Tcl extension up-to-date. That's mostly because I don't actually use tcl myself. If someone else wanted to use tcl and ifeffit together, and/or take over this module, that would be great! --Matt
