Re: Build fail on 64 bit Ubuntu

[Salvador Pinto Abreu]

Hi Sean,

If you grab the latest on Ubuntu, it should work: 
https://launchpad.net/ubuntu/+source/gprolog

I think this is about pie (position-independent executable), which appears to 
default to on in recent gcc releases; you can also recompile adding -no-pie to 
CFLAGS.
