Hi everyone,

I have a little patch here for numpy/distutils/fcompiler/gnu.py, which  
seems to relieve the dynamic_lookup problem
when linking a .so :

My problem with this solution is the following:

in the function get_flags_linker_so(), there is a line of code in the  
beginning:

 >> opt = self.linker_so[1:]

where the opt array is modified in the following, then returned. What  
I noticed is that
whatever is put into that array is not passed on. So my solution here  
is to directly modify the
self.linker_so array with the corresponding options. I do not think  
that this is a clean solution,
but it works for the moment. I'd be glad if you could comment a bit on  
the patch (if it is okay, if
the problem should be solved elsewhere, etc.).

Thanks,

ulrik
