Hi Michael
thanks a lot! Tkinter is now working fine for me and I can use
matplotlib with the TkAgg backend
For the record, here are the steps I followed to get it working on Mac
OS (10.4 and 10.5)
1) Download the Tcl/Tk sources
2) Compile the unix version (of Tcl and Tk) as follows
./configure --enable-framework --disable-xft, make, make install
3) Modify the setup.py file in the src directory of python-2.5.2.p8 by
putting
/System/Library underneath /Library/Frameworks at the top the
function detect_tkinter_darwin
4) run ./spkg-install in python-2.5.2.p8
5) reinstall matplotlib: sage -f matplotlib-0.98.3.p4
As this is the way Apple recommends to do it in the developer
documentation. I suggest that
the fix in the function detect_tkinter_darwin of the python-2.5.2.p8
setup.py gets included in the official Sage release. People needing
Tkinter on mac would then just need to have Tcl/Tk without
xft installed before compiling Sage.
Best wishes and thanks for the great job you are doing with the Sage
developers and maintainers,
Eric
