[lustre-discuss] Lustre Client on Fedora 23

[Patrick Farrell]

Michael,

I suspect a change in GCC/ld behavior as the cause for your original 
error.  I don't think setting PIC mode is the answer, since that doesn't 
work for kernel mode code.  I think you're probably compiling Lustre 
with an extremely new GCC/ld version, and some behavior change there is 
causing a failure.

Since it's just in the configure check to see if we're doing cross 
compiling, perhaps you can short-circuit that check?  Find it and 
replace it with false (assuming you are not cross compiling...).

Anyway, I think that error is where you should focus.  You could try 
rebuilding Lustre directly from source, but I bet you'll hit the same 
error in configure.
