Thanks.  Looks like this would let me compile it on X86_64 so it's a better answer than mine.

<p>The following can help:</p>

<pre><code>cd leveldb
make clean
cd ..
make -f makefile.unix USE_UPNP=-
</code></pre>

Why? What good is this? Why do you suggest it?

Just because i got exactly the same problem while compiling a couple of other coins and the above commands solved it. So it would be nice to hear why did you downvote my answer. Did you try my recommendation?

I did not downvote your answer, but it was flagged as low-quality. I put my comment there, because I think it could use more explanation: For example what directory you started out in. What 'make clean' is supposed to do for you, and so forth. As it is, this answer is extremely short and it is not easy to determine whether the answer is correct or valuable, unless you have the same problem as the OP.

Sorry everyone, I forgot about this one. In the end, I switched to an x86 platform and it compiled. I also should have specified that I was only trying X86_64.
