On the last meeting [1] we talked about whether we need maven and rh-java-common for rebuilding devtoolset-3. Unfortunately it is a requirement right now, so we need to have maven and rh-java-common collections first. However, the maven and rh-java-common SCL dependencies are needed just for the devtoolset-3-ide part, so for devtoolset-3-toolchain and devtoolset-3-perftools we may remove the requirements temporarily. Anyway, there have been requests for devtoolset and gcc-5 especially, often from other projects based on CentOS, so copr builds are not enough. We're still not ready with the centpkg/lookaside-cache things, but what about to create necessary tags from devtoolset-3 collection and build packages from srpms for now? Thomas, is it ^ possible? What information do you need from me? Let's limit on sclo part and RHEL-7 only. Based on the tags we consulted before, that should mean to create: * sig-sclo7-devtoolset-3-sclo tag * sclo7-devtoolset-3-sclo-el7 target and associated buildroot Correct? Will it be possible to tag built packages (I speak still about scratch builds) to sig-sclo7-sclo, which other SIGs could depend on?
