Does anyone on the planet know how to build python-2.5 (WITH READLINE)?

I am having one "hades" of a heckuva time getting
readline support for 
Python-2.5 on a Mac OS 10.4.8.8.0

with Xcode 2.3( Darwin Kernel Version 8.8.0; RELEASE_PPC
Power Macintosh 
powerpc)

I can get readline-5.2 (finally) to compile and build...

Then I try build Python-2.5, with readline....by changing
the 
/Modules/Setup file...to include readline...

and I always get the below-mentioned error.

I can NOT use the std' packages/path...as we use an absolute
path for 
our server farm called,

"/usr/lanl"

EG

/usr/lanl/packages <- where python/scipy/numpy/readline
src has gone.

/usr/lanl/bin

/usr/lanl/include

/usr/lanl/lib

/usr/lanl/man

This has been an EXTREME challenge on Mac 10.4

t.

NOTE: I attempted to copy all files (esp *.o) over to my
Python build 
dir, and it still fails...the following error, was the error
before 
doing that...

Here is the error:

Have you looked at Mac/BuildScript/build-installer.py in
Python's  
source distribution? That's how the official binaries for
OSX get  
build, includeing readline support.

You probably have to add the directory containing readline
to the  
CFLAGS and LDFLAGS when running Python's configure, AFAIK
setup.py  
doesn't automaticly look for readline in
$prefix/{lib,include}.

Since readline is an extension module I think you want to
specify this stuff
to distutils, e.g.:

    % ./python.exe ../setup.py build_ext --help
    Common commands: (see '--help-commands' for more)

      setup.py build      will build the package underneath
'build/'
      setup.py install    will install the package

    Global options:
      --verbose (-v)  run verbosely (default)
      --quiet (-q)    run quietly (turns verbosity off)
      --dry-run (-n)  don't actually do anything
      --help (-h)     show detailed help message

    Options for 'PyBuildExt' command:
      --build-lib (-b)     directory for compiled extension
modules
      --build-temp (-t)    directory for temporary files
(build by-products)
      --inplace (-i)       ignore build-lib and put compiled
extensions into the
                           source directory alongside your
pure Python modules
      --include-dirs (-I)  list of directories to search for
header files
                           (separated by ':')
      --define (-D)        C preprocessor macros to define
      --undef (-U)         C preprocessor macros to undefine
      --libraries (-l)     external C libraries to link with
      --library-dirs (-L)  directories to search for
external C libraries
                           (separated by ':')
      --rpath (-R)         directories to search for shared
C libraries at runtime
      --link-objects (-O)  extra explicit link objects to
include in the link
    ...

which suggests something like

    ./python.exe setup.py build_ext
--include-dirs=/sw/include --library-dirs=/sw/lib

I have fink installed, hence the references to /sw/...

As proof for the OP that it can be done:

Changing the CFLAGS/LDFLAGS at configure time works to (at
least on  
darwin/OSX systems). I applied a patch to that effect in 2.4
and 2.5  
because I got mightily annoyed with this. Before my patch
you could  
specify other CFLAGS/LDFLAGS as much as you liked, but the
autodetect  
code in setup.py would never use that. With my patch the
include and  
library directories in those variablese are used to
autodetect  
readline and other libraries.

The reason this is only done on OSX is that I never got
around to  
asking on python-dev if this behaviour is useful on other
platforms  
as well (IMHO it is, and the code should work at least on
Linux and  
other GCC-using platforms).

Thanks to Ronald and Skip for replying to this thread.  It
took me a  
little bit to connect the dots from their replies, so I
thought I'd  
share my experiences.  Maybe this can help someone, and
maybe also  
lead to Ronald or someone else clarifying the right way to
use his  
CFLAGS and LDFLAGS patch.

I'm using darwinports, so first I had to

sudo port install readline

Once that was done, I wanted to build a local, non-framework
Python  
with readline.  darwinports uses /opt/local, so Ronald's
approach led  
me to this best guess:

$ CFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib
./configure -- 
prefix=/Users/gary/py
$ make

However, that was unsuccessful.

$ ./python.exe
Python 2.4.4 (#1, Nov 30 2006, 20:36:29)
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright",
"credits" or "license" for more
information.
 >>> import readline
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
ImportError: No module named readline

Maybe someone could let me know what I did wrong?

Skip's approach was a little more unusual, at least to me,
since it  
was a step in-between `make` and `make install`.  However,
it  
worked.   If, after
a configure and a make (but, again, before a  
make install) I run this command...

$ ./python.exe setup.py build_ext
--include-dirs=/opt/local/include -- 
library-dirs=/opt/local/lib

...then readline appears in glory.

$ ./python.exe Python 2.4.4 (#1, Nov 30 2006, 20:36:29)
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright",
"credits" or "license" for more
information.
 >>> import readline
 >>>

Yay!

Of course, I could have copied readline.so from MacPython
but that  
would have been cheating. 

HTH someone

This should do the trick, more or less. The build script for
the  
python.org installer uses:

./configure --prefix=/Users/gary/py LDFLAGS=-L/opt/local/lib
OPT=-I/ 
opt/local/include

> $ make

If you're using macports you might as well do 'port install
python2.4'.
