Install h5py in Mac OS X 10.6.3

I'm trying to install h5py in Mac OS X 10.6.3.

First I installed HDF5 1.8, which used the following commands:

./configure \
--prefix=/Library/Frameworks/Python.framework/Versions/Current \
--enable-shared \
--enable-production \
--enable-threadsafe \
CPPFLAGS=-I/Library/Frameworks/Python.framework/Versions/Current/include \
LDFLAGS=-L/Library/Frameworks/Python.framework/Versions/Current/lib

make
make check
sudo make install

Then install h5py:

/Library/Frameworks/Python.framework/Versions/Current/bin/python \
setup.py \
build \
--api=18 \
--hdf5=/Library/Frameworks/Python.framework/Ve开发者_如何学运维rsions/Current

Then I got the errors:

******************************************

    Custom HDF5 dir:       /Library/Frameworks/Python.framework/Versions/Current

Failed to compile HDF5 test program.  Please check to make sure:

* You have a C compiler installed
* A development version of Python is installed (including header files)
* A development version of HDF5 is installed (including header files)
* If HDF5 is not in a default location, supply the argument --hdf5=<path>

I just updated my Xcode, I don't know whether this is because my gcc's default setting. If so, how can I get rid of this error?

Thanks.

I just came across a similar error while trying to build a Python extension module on Mac OS X with the Intel C/C++ compiler. To fix the "undefined symbols: _main" error I had to add the following to the linker command: -bundle -undefined dynamic_lookup

You can do a 'man ld' to find out what the specific linker commands do, but basically you are telling the linker not to worry about undefined symbols and to look them up dynamically when the library gets loaded.

If you use macports try: py26-h5py
