It seems so, as it FTBFSes if you remove the binaries from boot/.
They are used only for the first phase of bootstrapping. Then, everything is recompiled using the newly compiled binaries. And again. Until there is a fixpoint. Everything that eventually ends up in binary packages has been compiled from source, and using binaries that have been compiled from source. > That's RC, I think. With the way I explained above, I disagree. Also, there is no guarantee that one version of ocaml can compile the next one: a new version of the compiler is free to use the new features it introduces. Upstream only supports compiling one version with itself. Cheers, -- Stéphane -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
