[Matplotlib-users] matplotlib can't find pygtk during build

[Stephen U. <suh...@gm...>]

I'm trying to build matplotlib with the GTK/GTKAgg backends but it
won't find my copy of pygtk:

mrhanky:/usr/local/src/matplotlib-0.87.7 uley$ sudo python setup.py build
GTK requires pygtk
GTKAgg requires pygtk
running build
running build_py
creating build
...........

I followed the python/numpy/scipy installation method here:
http://projects.scipy.org/pipermail/numpy-discussion/2007-January/025368.html

I installed pygtk (2.10.3) with mac/darwinports on my mac os 10.4
ppcmachine. I edited setupext.py to look for all the libs under
/opt/local. matplotlib seems to find libjpeg, libpng, et al, but it
can't find pygtk. How can I modify matplotlib, or  how should I
install pygtk so the it builds correctly?

Thanks-
-stephen

I'm pretty sure that MPL looks for it by trying to import it. does:

import pygtk

work with the version of Python you're using?

Those instructions are for the Universal Framework Python, that you can 
get from python.org and pythonmac.org/packages. That version does not 
play so well with Darwinports.

Are you using a darwinports python? that version of pygtk will probably 
only work with a darwinports python, and in that case, there may even be 
a darwinports matplotlib.

In general, you need to use all darwinports python stuff or no 
darwinports python stuff.

In theory, one could use PyGTK with he Framework build of python, using 
Apple's X11, but I've never seen a package for that.

Why do you want to use pygtk on a Mac? why not TK or wx, or even try the 
cocoa back-end, though I have no idea what state that is in.

import pygtk barfs. My python is from ActiveState (Framework) which
was recommended by the scipy people.

Here's the real saga. I had a working Fink installaiton of
python/numpy/scipy/matplotlib until an update to scipy broke critical
functions (fopen). The fix is in cvs, so this whole mess started in an
attempt to use a cvs version of scipy. So I followed the instructions
on the scipy site and in the link above. Python numpy, and scipy are
fine, but I can't get matplotlib to work with the system.

I tried wxpython2.6 first, but figure windows never got drawn on my
display, even when I used pythonw. So I tried pygtk because it worked
fine for me under fink and on my linux box. I thought I could build a
binary pygtk with darwinports and use it in my installation... I guess
not.

So here we are. What to do? I think these are my options:

1) Build a mpkg of pygtk using darwinports and install it under my
python. Is this possible?

2) Get wx working somehow. Where do I begin?

3) Cocoa backend? I didn't know there was one.

4) Go back to fink or darwinports  and fight these problems on the scipy side.

Which course do you (or anyone) recommend?

Thanks-

I wonder why, I don't what the advantages of it are over the pythonmac 
version -- last I heard it did NOT support Universal binaries, but maybe 
that makes things a bit easier, particularly for scipy, and there is no 
easy way to build universal binaries from Fortran.

You could (should) have re-built scipy inside your fink distro.

wxPython 2.6.3, as distributed on the wxPython site and pythonmac, 
should work with MPL. I've lost track of whether there is a properly 
built binary of MPL on pythonmac at this point. Search these archives, 
and you'll see discussion of how to do it, or send a note to me if this 
one fails:

http://pythonmac.org/packages/py24-fat/index.html

Russell, if  you're listening -- did you ever post your binary for 
Python2.4, wxPython2.6.3 ?

nope, PYGTK is a good option IF you want to stick with darwinports or 
Fink, but not if you want the more "mac native" setup.

not easily -- I don't think it's been done --someone correct me if I'm 
wrong.

> 2) Get wx working somehow. Where do I begin?

with the package above, the notes that should be on this list, and if 
you're lucky with Russell Owens' binary. If all that fails, drop me a 
note, either Russell or I should be able to get you going.

Note that there are some yet-unresolved issues with the wx back-end with 
wxPython2.8, at least on OS-X, so I'd stick with 2.6.3. OH, and I've 
lost track, are you using Python 2.4 or 2.5? It should all work with 
2.5, but I (and I think Russell) are using wxPython2.8 with Python 2.5 
and wxPython2.6 with Python 2.4.

It may not have ever matured -- anyone know?

If you had Fink all working, it might be easiest to start there -- you 
just need to re-build scipy with all the fink tools -- that should be 
much like building it on Linux.

I would like to add that I used to keep a unix/X11 build of python on 
my Mac in parallel with a framework build so I could test a GUI app 
on X11 and Aqua. (I build the stuff myself instead of using fink; I 
never could get comfortable with fink). In any case, I eventually 
gave up. Installing packages that had a GUI interface took extra work 
-- for the X11 python I had to temporarily hide the Aqua GUI stuff. 
Eventually I gave up and ditched the X11 version.

But if you *only* use fink then this comment is irrelevant--they've 
handled it for you.

It's up. Bob Ippolito put it up shortly after he got back from vacation.

So this should work, with the Python, numpy, wxPython2.6.3 that are also 
there:

[Stephen U. <suh...@gm...>]

Hmm... After the long discussion I'm trying to decide what the best
route is. If what I want is simply a stable scipy/matplotlib
installation (OS X), what is the best (most stable and predictable)
method?

BTW- What is wrong with the ActiveState python installation? It was
recommended on the scipy site.

I'm very sorry to say that I don't know that there is a best. I, and 
others, have tried to keep the archive at pythonmac up to date, but 
building SciPy is still a pain in the %$$%^%, and there is no easy 
solution unless (until) Apple of someone puts out a Fortran compiler 
that makes Universal binaries.

However, if you like (or don't mind) fink or darwinports, that may be 
the easiest way to go -- you should be able to use them to build stuff 
yourself if the package you want is not up to date.

They don't support Universal binaries either, but that only matters if 
you want to re-distribute them.

I have no idea. At one point, it didn't support Universal binaries -- 
that may not be true anymore, and may not matter for you anyway.

There are WAY too many ways to install Python on OS-X. A while back, the 
MacPython community (that is, the folks on the pythonmac mailing list) 
decided that the Universal Framework Build, as found on pythonmac.org 
and python.org should be advocated as "the" way to do Python on OS-X, 
and the one that we would try as best we could to support with binary 
packages, and support on the mailing list.

Fink and darwinports are other beasts altogether, and take care of 
themselves.

I don't know what ActiveState's goal are with their build. At one point 
they had a package repository of some kind -- do they now?
