Problem trying to install PyCurl on Mac Snow Leopard

Question

Hi,

My app needs to use PyCurl, so i tried to install it on my Mac but i found a lot of problems and error :(

Requirement: First of all i've to say that the version of Python working on my Mac is 32 bit based, because i need to use WxPython, that needs 32 bit Python. For doing this i used:

defaults write com.apple.versioner.python Prefer-32-Bit -bool yes

To install PyCurl i used:

sudo env ARCHFLAGS="-arch x86_64" easy_install setuptools pycurl

And the terminal returned:

Best match: setuptools 0.6c11
Processing setuptools-0.6c11-py2.6.egg
setuptools 0.6c11 is already the active version in easy-install.pth
Installing easy_install script to /usr/local/bin
Installing easy_install-2.6 script to /usr/local/bin

Using /Library/Python/2.6/site-packages/setuptools-0.6c11-py2.6.egg

Best match: pycurl 7.16.2.1
Processing pycurl-7.16.2.1-py2.6-macosx-10.6-universal.egg

Using /Library/Python/2.6/site-packages/pycurl-7.16.2.1-py2.6-macosx-10.6-universal.egg
Processing dependencies for pycurl
Finished processing dependencies for pycurl

so i thought that pycurl was correctly installed and working. But...

But when i started my app, python return me an error:

python /Users/lorenzodenobili/Desktop/Python/AGGIORNATORE_PY/Dropbox/wxPython/test.py  
Traceback (most recent call last):  
  File  "/Users/lorenzodenobili/Desktop/Python/AGGIORNATORE_PY/Dropbox/wxPython/test.py", line 20, in <module>

    /Users/lorenzodenobili/.python-eggs/pycurl-7.16.2.1-py2.6-macosx-10.6-universal.egg-tmp/pycurl.so: mach-o, but wrong architecture  

Yep, there is something quite big that goes wrong.

I really don't have any idea on how to solve this error, so i really need your help!

thank you so much!!

Answer 1

You passed the following flags to the compiler when compiling PyCurl:

ARCHFLAGS="-arch x86_64"

It seems that you have compiled PyCurl in 64-bit mode, while you use the 32-bit Python. Have you tried it with ARCHFLAGS="-arch i386"?

Answer 2
