All,
Since I posted this message, I've received 4 personal emails from people
having similar problems. The Python.org python distribution makes it hard to
build extensions on Leopard, especially with gcc 4.2. I can't claim to
understand completely what the problems are but the makefile that comes in
the installer has:
- MACOSX_DEPLOYMENT_TARGET=10.3
- --enable-universalsdk=/Developer/SDKs/MacOSX10.4u.sdk
- BASICFLAGS= ... -Wno-long-double -no-cpp-precomp (doesn't work with gcc
4.2)
all of which can cause problems under some circumstances.
It would be great if someone could make sure that the python.org mac python
can build widely-used packages with compiled extensions like numpy,
matplotlib and pytables on leopard with a range of compilers, or else put
some caveats about its compatibility on the website.
I ended up building python from source, but I had to pass arguments to the
configure script, alter the makefile it generated and then hack Pyrex in
order to get everything working right. I don't remember exactly what I did
but if any files on my system would help I'd be happy to share them. I can
also go back and retrace the steps I took if necessary.
Thanks for your attention to this... it's hard to recommend colleagues to
switch to Python knowing that they'll have to start with a difficult source
install.
Please copy me directly if you respond.

Just to check, I downloaded the Python.org 2.5.2 distribution. Now when I
try to compile numpy I get the following. It works with gcc 4.0 but not gcc
4.2... but I need to use gcc 4.2 later on, so I want to get Python to play
nicely with it. How can I do that?
Thanks,
Anand
