<div dir="ltr">Hi all,<div><br></div><div style>I'm doing these things in the random minutes between everything else. So, I'm just going to dump a note, but be aware I haven't investigated yet.</div><div style>
<br></div><div style>I installed Ubuntu 12.04 LTS and followed our build instructions. </div><div style><br></div><div style>./build --with-toolchain=tvm --prefix=/something</div><div style><br></div><div style>And I bombed out here:</div>

<div><br></div><div style>So, I have the 32-bit library around, but perhaps it isn't in my library path? Or, perhaps it needs to be linked in somewhere? I'm assuming (potentially incorrectly) that my problem is that I couldn't find a 32-bit library for these operations.</div>
