I'm attempting to install matplotlib under version 10.5 ("Leopard") of
the Macintosh operating system.
I had an old installation, via Fink, which broke when I (foolishly)
upgraded from version 10.4 to version 10.5.
In principle, installing matplotlib under 10.5 should be simple,
because Leopard already includes all of matplotlib's dependencies:
Python 2.4 (and 2.5)
numpy
libpng
zlib
freetype
In practice, I seem to be running into trouble with freetype.
I built matplotlib version 0.90.1 from source, and installed it in /
Library/Python/2.5/site-packages
When I run python2.5 and import pylab, the import looks for freetext.
6.dylib in /sw/lib/freetype219/lib/libfreetype.6.dylib (i.e. the
broken Fink installation, incompatable with Leopard) which results in
a bus error. (My reasons for this assertion are given below.) There's
a (presumably Leopard-compatable) version of libfreetype.6.dylib in /
usr/X11/lib/libfreetype.6.dylib
...so, my problem seems to be, how do I get matplotlib to look for
libfreetype.6.dylib in the right place?
I have tried changing setup.py Specifically, I've replaced
'darwin' : ['/sw/lib/freetype2', '/sw/lib/freetype219', '/usr/local',
'/usr', '/sw'],
with
'darwin' : ['/usr/X11', '/usr/X11/lib', '/usr/X11/include', '/usr/X11/
include/freetype2', '/usr/local','/usr'],
Which does not solve the problem (does not change anything at all, as
far as I can tell).
I've not been able to locate an explicit reference to the /sw
directory anywhere else in setupext.py, or in setup.py
APPENDIX: why am I convinced that pylab is looking for freetype.
6.dylib in /sw/lib/freetype219/lib/ ?
First, when I get the bus error, a window pops up saying that Python's
"unexpected quit" (=crash) may be due to "freetype.6.dylib"
Second, when I click the "report" button in this window, I see many
pages of debugging info which I don't know how to interpret, but which
includes this line:
0x1226000 - 0x1279ff3 +libfreetype.6.dylib ??? (???) /sw/lib/
freetype219/lib/libfreetype.6.dylib
Third, when I temporarily remove the entire /sw/lib/freetype219
directory from /sw/lib then run python2.5 and import pylab, I no
longer get a bus error, but I *do* now get *this* error:
ImportError: dlopen(/Library/Python/2.5/site-packages/matplotlib/
ft2font.so, 2): Library not loaded: /sw/lib/freetype219/lib/
libfreetype.6.dylib
Referenced from: /Library/Python/2.5/site-packages/matplotlib/
ft2font.so
Reason: image not found
I am going to try some monkey business along the lines of
ln /usr/X11/lib/libfreetype.6.dylib /sw/lib/freetype219/lib/
libfreetype.6.dylib
and will let you know the results. However, even if that works, it's
a heinous kluge, and probably fragile, too.
