Hi again Matt, guys, So we kept on fighting with this issues, relating probably to flags on the instructions, relocating files and/or libraries, and we are still very stuck. Do you have any idea on what to explore, road to follow, crazy thoughts? Even a hint, if you don´t have time we can try it. Cheers!
Roberto,This is really useful, thank you so much! I have a Pi 2 at home aswell, and I tried for a few days to get NuPIC running on it, but alsoran into similar issues. I gave up and moved onto other things, but Iwould love to get this problem solved so it is easier to install on aPi.Regards,---------Matt TaylorOS Community Flag-BearerNumenta> > Message: 1 > Date: Mon, 6 Jul 2015 17:41:03 +0100 > From: Roberto Becerra <[email protected]> > To: "[email protected]" <[email protected]>, > "[email protected]" <[email protected]>, "[email protected]" > <[email protected]> > Subject: Nupic in Raspberry PI 2B > Message-ID: <[email protected]> > Content-Type: text/plain; charset="iso-8859-1" > > Hi all, Nupic guys, and sorry for the long thread :P > We have been working on porting Nupic to Raspberry PI 2 B, so far we have > successfully compiled and ran all the nupic system in a Linux 32 PC, we even > have notes that could be useful for others. > We did this in on a 32-bit machine first to find out how to compile Nupic > properly, and once having that naively thought to the same steps in the PI. > When we did so, we found a number of problems that have to do with the > Processor, we have been debugging them as we find them.
