This email (on the gumstix mailing list) describes the problem: http://sourceforge.net/mailarchive/message.php?msg_id=27373548. libc has moved in Ubuntu 11.04.
Later in that thread is a link to this OE patch: http://patches.openembedded.org/patch/1659/. Since I'm a Yocto and OE newbie, it's not clear to me if this patch can be applied to Yocto Project 1.0.1, and if so, how. I might be better off installing 10.10 on my machine. (It's new, so I don't need to worry about backing up and restoring any files.) But then I may be missing out on a learning opportunity and a chance to help out the community. Would someone be able to walk me through applying or adapting this patch to Yocto? -- Daryl On Wed, Jun 8, 2011 at 6:48 AM, Daryl Spitzer <daryl.spit...@gmail.com> wrote: >>>> Does this look familiar?
