Can Python ctypes load a 32bit C library on x86-64?
Question: I have a 64 bit RHEL host with 32 bit libraries installed. One vendor has a 32
bit .so I'd like to load into Python using ctypes.

    
    
    from ctypes import CDLL
    CDLL('32bitdinosaur.so')                        
    
    OSError: 32bitdinosaur.so: wrong ELF class: ELFCLASS32
    

Of course 64 bit libraries are OK. Eg:

    
    
    CDLL('libc.so.6')
    

Works fine.


Answer: It looks like the best way to do this is to have a 32 bit python in a separate
process load the .so, and call the 32 bit python from a 64 bit Python.
