Hello, I used your new beta installer to install matplotlib on a G5 running OS X 10.5.5. I tried the contour demo and got this error
pylab_examples$ pythonw contour_demo.py Traceback (most recent call last): File "contour_demo.py", line 12, in <module> import matplotlib.pyplot as plt File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/matplotlib/pyplot.py", line 6, in <module> from matplotlib.figure import Figure, figaspect File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/matplotlib/figure.py", line 19, in <module> from axes import Axes, SubplotBase, subplot_class_factory File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/matplotlib/axes.py", line 18, in <module> import matplotlib.image as mimage File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/matplotlib/image.py", line 19, in <module> from matplotlib import _png ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.5/ lib/python2.5/site-packages/matplotlib/_png.so, 2): Symbol not found: _png_destroy_read_struct Referenced from: /Library/Frameworks/Python.framework/Versions/2.5/ lib/python2.5/site-packages/matplotlib/_png.so Expected in: dynamic lookup I was able to build matplotlib by using MACOSX_DEPLOYMENT_TARGET. I built libpng 1.2.33, freetype 2.3.7 and pkgconfig 0.23 with gcc 4.0.1 from XCode 3.1.2. to build and install matplotlib I did env MACOSX_DEPLOYMENT_TARGET=10.5 python setup.py build sudo env MACOSX_DEPLOYMENT_TARGET=10.5 python setup.py install I don't get "Symbol not found:" errors for _png.so now, but negative signs on numbers in the axis labels appear as boxes instead of -'s. I may try the freetype in /usr/X11 instead of the one I compiled. Thanks for all the work on matplotlib, Scott ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
