Do any Mac experts have any ideas? One thing that may help us is to fire this up in gdb and get a traceback.
1) Run "gdb python" (or "gdb python3"). 2) At the gdb prompt, type "run" 3) At the Python prompt, type "import matplotlib.pyplot" 4) Python should crash, then type "bt" to get a backtrace 5) Post the *complete* backtrace to this list and maybe it will make the problem more obvious to us Mike On 07/08/2013 12:17 PM, p.maxted wrote: > Trying to install matplotlib-1.2.1 from source, i.e., > > [macpflm:~/matplotlib-1.2.1] pflm% python3 setup.py install > > Everything seems to run ok, but I cannot import macplotlib: > > [macpflm:~] pflm% python3 > Python 3.3.1 (v3.3.1:d9893d13c628, Apr 6 2013, 11:07:11) > [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin > Type "help", "copyright", "credits" or "license" for more information. >>>> import matplotlib.pyplot > Python(16295) malloc: *** error for object 0x101c86820: pointer being freed > was not allocated > *** set a breakpoint in malloc_error_break to debug > Abort > > > I tried updating libpng and freetype using macports and re-building, it did > not solve the problem. > > There are some warnings printed during the build, e.g., > > ld: warning: in /opt/local/lib/libfreetype.dylib, file was built for > unsupported file format which is not the architecture being linked (i386) > ld: warning: in /opt/local/lib/libz.dylib, file was built for unsupported > file format which is not the architecture being linked (i386) > ld: warning: in > /Developer/SDKs/MacOSX10.6.sdk/usr/local/lib/libstdc++.dylib, file was built > for unsupported file format which is not the architecture being linked > (i386) > > ..and.. > > /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/numpy/core/include/numpy/npy_deprecated_api.h:11:2: > warning: #warning "Using deprecated NumPy API, disable it by #defining > NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" > > (both warning several times). > > Some details from the start of the screen output during the build. > basedirlist is: ['/usr/local/', '/usr', '/usr/X11', '/opt/local'] > ============================================================================ > BUILDING MATPLOTLIB > matplotlib: 1.2.1 > python: 3.3.1 (v3.3.1:d9893d13c628, Apr 6 2013, 11:07:11) > [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] > platform: darwin > > REQUIRED DEPENDENCIES > numpy: 1.7.0 > freetype2: 16.2.10 > > OPTIONAL BACKEND DEPENDENCIES > libpng: 1.5.16 > Tkinter: Tkinter: version not identified, Tk: 8.5, Tcl: 8.5 > Gtk+: no > * Building for Gtk+ requires pygtk; you must be able > * to "import gtk" in your build/install environment > Mac OS X native: yes > Qt: no > Qt4: no > PySide: no > Cairo: no > > OPTIONAL DATE/TIMEZONE DEPENDENCIES > dateutil: matplotlib will provide > pytz: matplotlib will provide > six: matplotlib will provide > > OPTIONAL USETEX DEPENDENCIES > dvipng: 1.5 > ghostscript: 6.01 > latex: 3.141592 > > [Edit setup.cfg to suppress the above messages] > ============================================================================ > > Help! > > > > > > -- > View this message in context: > http://matplotlib.1069221.n5.nabble.com/Install-problems-OSX-10-6-8-Python-3-3-1-tp41430.html > Sent from the matplotlib - users mailing list archive at Nabble.com. > > ------------------------------------------------------------------------------ > This SF.net email is sponsored by Windows: > > Build for Windows Store. > > http://p.sf.net/sfu/windows-dev2dev > _______________________________________________ > Matplotlib-users mailing list > Matplotlib-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/matplotlib-users ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
