I have a new intel powerbook running OS X 10.5
(leopard) which I upgraded via DVD from a factory installed 10.4. I
decided to take detailed notes on every step of configuring the box as
a development machine for scientific python, figuring it would be
useful to others. The install of ipython, numpy and scipy went really
well (only one snag in scipy following the wiki, which I updated and
is noted in my notes below). But the main problem, sadly, is a
strange problem I've hit trying to compile matplotlib.
My compile is dying with a mysterious
warning about PPC (how did that get in to the compiler flags?) with
some strange hybrid
of 10.4 and 10.3 stuff in the gcc command. If I manually paste in the
g++ command below and remove the -arch ppc part, it compiles fine, so
this is the source of my problems. I don't know if this is a feature
or a bug (universal binary support?) but if someone could advise me
what or where is going wrong and how to fix it, that would be great.
Here is the shorted build output with the compiler command and error:
