Symbol not found, when importing on Snow Leopard

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?

1. Install healpy 0.9.6.3 with Python 2.5.4, numpy 1.2.1, matplotlib
0.98.5.3, pyfits 2.2.2 on Mac OS X 10.6.2
2. Run python, import healpy

What is the expected output? What do you see instead?

Expect to see no output, module should import with no errors. Instead, see
following information:
>>> import healpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "healpy/__init__.py", line 34, in <module>
  File "healpy/pixelfunc.py", line 21, in <module>

What version of the product are you using? On what operating system?

Using healpy 0.9.6.3. Same problem occurs with 0.9.6 and 0.9.4. On Snow
Leopard (Mac Os X 10.6.2) with pre-installed version of python 2.5 (2.5.4).

install healpy. numpy 1.2.1 pre-installed with python 2.5 on Snow Leopard.

Python 2.5 does not support 64-bit libraries., while healpix library, which is 
compiled independently, will be 
compiled in 64-bit mode by default. To solve this problem, either switch to 
python 2.6 (which supports 64-bit 
by default), or modify the file hpbeta/config/config.generic_gcc to insert the 
option ' -m32 ' just after ' = ' on 
lines CCFLAGS_NO_C, CXXCFLAGS_NO_C and CXXLFLAGS.

Changed state: Fixed

Thanks, Cyrille. I've switched to python 2.6 and healpy now works. If anyone 
else is
having trouble getting pylab, numpy, scipy, etc. to install on Snow Leopard 
with a 64
bit processor, here are a couple of solutions:
