Hi Kris, In the dependency chain for gcc-arm-linux-gnueabihf and friends from the emdebian.org/tools/debian repo there are dependencies with strict version requirements on packages in the official Jessie repositories---e.g., libgcc-4.9-dev:armel (= 4.9.2-10). Eventually, some of those packages in Jessie were updated in point and security releases---e.g., to 4.9.2-10+deb8u2. The packages in emdebian.org/tools/debian didn't get updated, however, hence the error you're seeing. If you download the relevant source package, cross-gcc-4.9-armhf and perhaps a few others, from emdebian.org/tools/debian and rebuild against the latest point release of Jessie (perhaps with security updates too), you'll eventually get a set of packages that will work on the version of Jessie against which you build. Alternatively, I suppose, you could install an older point release of Jessie and use the packages from emdebian.org/tools/debian as-is. Good luck. -- Ryan
