A couple of weeks ago I got a new powerbook and installed leopard on it, and decided to keep fairly detailed notes of the process of getting developer svn versions of some of the scientific python tools installed (matplotlib, ipython, numpy, scipy aka MINS). The notes will probably apply equally well for the released versions, but or those of you embarking on getting a new OS X environment, up and running, this might be helpful. I tried to leave nothing to the imagination so that this would be useful to newbies, so some of this will be a bit tedious to unix or max veterans
== get access to the terminal == Put the "Terminal" on your dock launch bar. It is in the Applications->Utilities folder == install gcc and other developer tools == Install XCode developer tools from the Leopard install CD under optional packages. Verify the install -- check for a working gcc > gcc --version i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465) == get the mac python python release == The consensus is that the python that ships with Apple is broken and should be replaced with the universal binary from the mac python community. Go to the mac python site for downloads and install the python 2.5 universal binary from there http://www.pythonmac.org/packages/py25-fat/index.html Verify the python install > /usr/local/bin/python Python 2.5 (r25:51918, Sep 19 2006, 08:49:13) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin Type "help", "copyright", "credits" or "license" for more information. Make sure that /usr/local/bin is in your PATH before the Apple defaults. I added this to the front of my default .bash_profile PATH="/usr/local/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}" export PATH Start a new terminal instance and verify > which python /usr/local/bin/python Get whatever else you want from pythonmac.org == get svn checkouts of MINS == I am going to be installing most things from svn since I need developerversions of many packages, but you may just want to get the latest stable releases from this pythonmac site. In particular, I always run svn ipython, numpy, scipy and matplotlibx = ipython = > svn co http://ipython.scipy.org/svn/ipython/ipython/trunk ipython > cd ipython > sudo python setup.py install = numpy = > svn co http://svn.scipy.org/svn/numpy/trunk numpy > cd numpy > sudo python setup.py install = scipy = > svn co http://svn.scipy.org/svn/scipy/trunk scipy http://scipy.org/Installing_SciPy/Mac_OS_X gives step-by-step instructions to install the vecLib Framework (should have been done in step one of the developer tools above) g77 compiler, the fftw libs, and the scipy build commands, do I won't repeat them here. The only gotcha was I got an internal compiler error "qelg.f:1: internal compiler error: vector VEC ..." when I downloaded the intel gfortran binary linked from the site, so I grabbed the gfortran-intel-leopard-bin.tar.gz from http://hpc.sourceforge.net/ and reinstalled using > sudo tar -xvzf gfortran-intel-leopard-bin.tar.gz -C / and then did a clean build of scipy = matplotlib = matplotlib wants a GUI, so I am going to try wxpython2.8, which is available from the pythonmac ite. Because I am interested in installing the enthought tools which need wxython (eg traits UI) I'm going to see if I can get a wx enabled build of mpl going. I installed wxPython2.8-osx-unicode-2.8.3.0-universal10.4-py2.5.dmg from the pythonmac site and am crossing my fingers that I don't find myself entangled in wx version hell. > svn co https://matplotlib.svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib matplotlib depends on libpng and freetype, both of which are provided by the xcode package in /usr/X11R6, so I am going to point the mpl build to that directory. sys.platform is "darwin", so edit setupext.py and add '/usr/X11R6' to the "basedir" dictionary for the 'darwin' key. You need to install pkgcong-0.22 from http://pkgconfig.freedesktop.org/releases/ (just configure, sudo make install it) so that matplotlib can use it to find an properly configure png and freetype. You will need to set the pkgcong path > export PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig After all that, I could build mpl from svn with > python setup.py build > sudo python setup.py install and successfully make a figure with > ipython -pylab >>> plot([1,2,3]) which used the wxagg backend. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
