[Matplotlib-users] O pylab why do you refuse to import?

From: John S. <pra...@ho...> - 2009-05-06 21:53:51

Hi- I'm writing again. 

I managed to switch my python version to 2.5, and reloaded numpy and matplotlib. Unfortunately, pylab still will not load:

>>> import pylab
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/pylab.py", line 1, in <module>

  Referenced from: /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/ft2font.so

What is going on? Is ft2font.so broken?

I'm using python 2.5.2 on a macbook, intel microprocessor, mac os 10.4.11

how did you install matplotlib?

  Unfortunately, pylab still will not load:

does that file exist?

If so, try running:

$ file ft2font.so

and see what it says -- it may be a PPC- only binary.

Here's what it says:

$ file ft2font.so
ft2font.so: Mach-O universal binary with 2 architectures
ft2font.so (for architecture i386):     Mach-O bundle i386
ft2font.so (for architecture ppc):      Mach-O bundle ppc

I installed matplotlib from the dmg file. I clicked on the icon to install it.

that's right, but now I see that that wasn't the issue anyway:

ft2font is relying on libfreetype. I think that's the one that Apple 
delivers with their X11 (I know I have it, anyway), but I think X11 is 
an optional install, so you may not have it.

Is that file there? ON my system:

$ file /usr/X11R6/lib/libfreetype.6.dylib
/usr/X11R6/lib/libfreetype.6.dylib: symbolic link to `libfreetype.6.3.dylib'

and

$ file /usr/X11R6/lib/libfreetype.6.3.dylib
/usr/X11R6/lib/libfreetype.6.3.dylib: Mach-O dynamically linked shared 
library ppc

so I have it, and it's a ppc lib, which makes sense, as I'm running on a 
ppc machine.

If you don't have it, probably the easiest thing to do is install 
Apple's X11 -- otherwise, perhaps MPL should be built against a static 
libfreetype.

I do have X11. It looks like there's a problem with the libfreetype, but I don't understand what the problem is.

From: Joshua L. <dis...@gm...> - 2009-05-07 04:19:52

John,

I've seen this problem happen before with someone else; the person's
X11 installation for some reason included the file
libfreetype.6.3.dylib but not librfreetype.6.3.dylib. Did you install
X11 before or after installing the Xcode development tools? Also, if
you had to install X11 yourself, I'm assuming you're using OS X Tiger
(or at least not 10.5.x)? I'd recommend trying a reinstall of X11 (if
you're not using Leopard) and then Xcode in your situation, but a
quicker workaround is to install freetype yourself (thus putting a
copy in /usr/local) and build matplotlib from source rather than use
the installer package.

From: John S. <pra...@ho...> - 2009-05-07 15:48:49

Victory!

Turns out that libfreetype in X11 has a bug with mac os 10.4.11. I found out how to fix it on http://forums.macosxhints.com/archive/index.php/t-98792.html . The new libfreetype, once in the right spot and called libfreetype.6.dylib seems to work.

Thanks, Chris, for helping me.

Victory!

Turns out that libfreetype in X11 has a bug with mac os 10.4.11. I found out how to fix it on http://forums.macosxhints.com/archive/index.php/t-98792.html . The new libfreetype, once in the right spot and called libfreetype.6.dylib seems to work.

Thanks, Chris, for helping me.

I do have X11. It looks like there's a problem with the libfreetype, but I don't understand what the problem is.

[Matplotlib-users] OS X binary installer broken on 10.4? (was: O pylab why do you refuse to import?)

I assume you mean the mpkg file - I don't see any dmg file on the
download page. It seems to me that something is wrong with that file,
since release/osx/Makefile compiles its own Freetype and attempts to
link to it statically, but the file ft2font.so distributed within the
mpkg installer links dynamically to /usr/X11R6/lib/libfreetype.6.dylib.

AFAIK, the static linking is done precisely to avoid version mismatches
between different versions of freetype, zlib, and png on various
versions of OS X. Several *.so files within the mpkg link to
/usr/X11R6/lib/libfreetype.6.dylib and /usr/lib/libz.1.dylib (though,
curiously, none link to the system libpng).

I suppose this is exactly the kind of problem that results from dynamic
linking to a wrong version of freetype:

If it works, you're probably done, but, for the sake of completeness, 
what do you get from:

$ ls -l  /usr/X11R6/lib/libfreetype*

-rw-r--r--   1 root  wheel  348476 Jan 21 07:27
/usr/X11R6/lib/libfreetype.6.3.dylib

lrwxr-xr-x   1 root  wheel      21 Aug 14  2008
/usr/X11R6/lib/libfreetype.6.dylib -> libfreetype.6.3.dylib

-rw-r--r--   1 root  wheel  831260 Mar 23  2007 /usr/X11R6/lib/libfreetype.a

lrwxr-xr-x   1 root  wheel      21 Aug 14  2008 
/usr/X11R6/lib/libfreetype.dylib -> libfreetype.6.3.dylib

This is the traditional *nix convention:

the real lib is libfreetype.6.3.dylib  (major an minor version specified)

The other ones are links to it.

I suspect that you where missing the libfreetype.6.dylib link before, 
and that you may now have a full lib there, rather than a link. Which 
probably is fine, but not quite standard.

I too have been bit by related freetype problems...

Is there a way of telling matplotlib which freetype dylib to use on OS
X?  I have multiple installed and it finds the wrong one by default.
I can probably go and hack on the setup.py/setupext.py to do this but
I am hoping there is any easier way.

Thanks,

Brian

Well, it was done originally because all those libs weren't there at all 
originally. Apple has slowly been adding more (and the first freetype 
they included was not compatible with MPL in some way)

But yes, if there are different versions floating around static linking 
is a good idea.

I think zlib as been pretty reliable, freetype not so much, and I don't 
think Apple provides libpng at all (I've got a whole bunch of copies on 
my system that came with various packages -- but none in system locations)

In this case, I think a symlink was missing -- which looks like an Apple 
bug, but I can't tell you why it didn't bite me -- I suppose it depends 
on what order you installed/upgraded things.

at run time, no. At built time, then:

that's how.

The tough part is that AFAICT, there is no way to specify a particular 
lib to link to, rather, you specify where to look for libs, so you need 
to make sure that it's looking where you want before where you don't want.

Ideally, the MPL community would decide on which is the "canonical" 
choice, and that would be how setup.py would be written. But there are 
so many options, it's hard to come to consensus.

Personally, I'd like to see the "Kyng Chaos" frameworks be the 
"standard" basis for python extension binaries:

http://www.kyngchaos.com/software:frameworks

That's a pretty complete set, and would support MPL, PIL, etc, etc....

But it seems folks prefer to do static linking for distributed binaries, 
which is good too, but a bit tricky, as gcc really prefers to 
dynamically link -- it's easy to accidentally include a dynamic link 
without realizing it.
