I'm trying to get started with OpenEmbedded, but I'm running into an issue just trying to build the "console-image" recipe. I'm on Ubuntu 10.04 32-bit. I did the prereqs for OpenEmbedded using http://wiki.openembedded.net/index.php/OEandYourDistro. I installed the packages manually instead of using the respository/meta-package from http://blog.leggewie.org/?p=39. All the packages installed fine except "apr", there's no such package in Ubuntu's repository, but I did install libapr1-dev and libaprutil1-dev. There was no alternative for git. I reconfigured dash to not be used. I put 'BUILD_CPPFLAGS += "-Wno-format-security -U_FORTIFY_SOURCE"' at the top of my local.conf in ~/oe/chumby/conf. I installed BitBake v.1.8.18 through apt-get. Git seemed to download the sources fine. I grabbed the zip file with the Chumby specific configuration, edited the setup-chumby.sh" script to point at my ~/oe directory (I actually use ~/OpenEmbedded) and ran "source setup-chumby.sh" and chose Silvermoon. When I try to build the console image with "bitbake console-image" it goes through handling the 7307 files, then I get:

NOTE: Handling BitBake files: / (7307/7307) [100 %]

I got the same results in VirtualBox and on a real install. Any thoughts what I need to fix? Thanks.
