Re:compiling outloud on 64 bit ubuntu

["Tim Cross" <tcross@xxxxxxxxxxx>]

Hi Bart,

from the errors you get, my guess is that you don't have a full 32 bit library
chain in your build. You need to have the 32 bit versions of all the libraries
involved to get it to work - this would include tcl and alsa 32 bit libs as
well as the C++ libraries and possibly that compat package etc. 

Possibly the way to go would be to do the build on a 32 bit system, run ldd to
list all the dependencies and then make sure you have all of those libs in the
32 bit lib hierarchy. 

I seem to remember a post from Raman where he outlined what he had to do.
should be in the archive. It was a while back and I can't remember if it was
outloud or espeak he was building, but I do remember it was 32 bit.
