Building Python with non-standard tcl/tk support

[Steven D'Aprano]

I'm trying to re-build Python 3.2 with support for TCL/TK 8.5, but when I
run "make" I get this message:

Failed to build these modules:
_tkinter

and after installing 3.2 I still have this:
'8.4'


What do I need to do to have Python 3.2 use tcl/tk 8.5?


I have installed tcl/tk 8.5.11 from source, and the binaries are here:

/usr/local/lib/libtcl8.5.so
/usr/local/lib/libtk8.5.so


In the Python 3.2 source, I do the usual:

../configure
make
sudo make altinstall


(altinstall to avoid nuking the system Python)

That's all you should have to do, but on my system the Tk libraries are
in /usr/lib not /usr/local/lib. So try doing ./configure
--prefix=/usr/local or try setting LDFLAGS to "-L/usr/local/lib".

Thanks, but that doesn't work. "make" still says it failed to build
_tkinter, and after "make altinstall" it still picks up tck/tkl 8.4.


Okay, now I'm making progress... if I remove the previously existing
_tkinter in lib-dynload, and re-run "make", I get something new:

Verify that libtk8.5.so exists in /usr/local/lib and verify you have
read permission.

You could try to write a Tk C program (or find one) and try building
that with cc -L/usr/X11/lib -L/usr/local/lib -ltk8.5 -ltcl8.5 -lX11 .
If that works then your Tk libraries are installed properly and
something is wonky with your Python build.
