Python 2.5 Installation and Tkinter

[milan_sanremo]

Under Solaris 10 I installed tcl 8.5 and tk8.5 and they work just fine.
I built both with
../configure -prefix /usr/local/python/lib

I then set LD_RUN_PATH to /usr/local/python/lib and ran the ./configure
for Python 2.5 with no arguments. When I run make, it states:

INFO: Can't locate Tcl/Tk libs and/or headers
running build_scripts

I verified that the libraries are in /usr/local/python/lib. If I run
/usr/local/python/bin/wish8.5 it works.

My path incudes /usr/local/python/bin:/usr/local/python/lib.

How do I get Python to recognize Tcl/Tk for the build?

I went back and rebuilt everything with the defaults. the tcl and tk
libs were written to /usr/local/lib.

Running python with the default settings does not find it. Changing
Modules/Setup TKLIB=/usr/local/lib still produces the error:

Yet, the file exists in /usr/local/lib. What am I missing?

The system doesn't look in /usr/local/lib when searching for shared
libraries. You have the usual options:

1. Set LD_RUN_PATH at build time to include /usr/local/lib
2. Set LD_LIBRARY_PATH at run time to include /usr/local/lib
3. Use crle to add /usr/local/lib to the system wide search path

Even though it is quite intrusive, I typically prefer to do 3.
That way, I don't have to hard-code library paths into executables,
don't need my users to set environment variables, and have most
autoconf-based software work out of the box.

If you have never used crle before, understand that great care
is necessary in using it. See the EXAMPLES in crle(8). You can
either use -u -l to add a directory at the end of the search
path, or just -l to overwrite the search path; make sure the
original search path is still included.

Thanks for the detailed reply. I tried you suggestions regarding the
linking and they produce a new error message.

Not sure whether it's a typo: If the file is in "/usr/loca/lib", you
should set LD_RUN_PATH to that, not "/usr/local/lib".

Are you sure LD_RUN_PATH is exported?

I would do "file /usr/local/lib/libtk8.4.so", to see whether it's
a "good" file.

Then I would invoke the linker line manually (so that _tkinter.so
doesn't get removed), and then do

ldd -s build/lib.solaris-2.10-i86pc-2.5/_tkinter.so

to see how it tries to resolve shared libraries.

HTH,
