It appears that if we depend on 'ros' in our stack.xml, the 'devel' build is not done due to this message: devel_fuerte_orocos_toolchain_precise_amd64 - Build # 16 - Fixed: Check console output at http://build.willowgarage.com//job/devel_fuerte_orocos_toolchain_precise_amd64/16/ to view the results. Result: Not all dependencies of stack orocos_toolchain have a Debian package. Skipping this devel build It tries to install ros-fuerte-ros, sees it's already there and then skips the build instead of proceeding... Can I just remove the dependency ? Will this not break other builds that do rely on it ? Cheers, Peter
