name: build-essential kind: stratum description: | Toolchain stratum Stage 1: build a minimal cross compiler with the host's tools. Starting with a cross compiler ensures that (a) nothing from the host can leak into the build-essential artifacts, and (b) cross-compiling build-essential is fully tested and supported, since we always use the cross code paths. Stage 2: cross-build the whole of build-essential, using the host's tools but the cross-compiler toolchain. Stage 2 GCC outputs code for the same 'bootstrap' machine as stage 1 GCC, but because stage 2 GCC is also built to *run* on the bootstrap machine it can only execute inside the stage 3 chroot (due to being built against a libc with a non-standard prefix). Stage 3: build the whole of build-essential again, this time using a staging area containing only the output of stage 2. The result of this build is fully reproducible. We do a switch-a-roo between stage 2 and 3: stages 2 chunks are all built to run on a host *-bootstrap-* while stage 3 chunks are native-built for a *-baserock-* machine. This works, because the cross build was all for show (and cleanliness) and the binaries actually still run on the host. After build-essential is built we do another trick. See stage2-fhs-dirs.morph for details. Basically, /bin is a symlink to /tools/bin during stage 2 but in stage 3 it becomes a real directory again. PLEASE KEEP THE REFS IN 'armv7lhf-cross-toolchain' STRATUM UP TO DATE WITH THIS ONE! Please note that the chunk 'build-depends' field is treated differently in this stratum to how other strata in definitions.git use it. Other strata rely on the fact that dependencies of a dependency (called 'transitive dependencies') are implicitly included in the staging area. Within build-essential, some chunks list transitive dependencies explicitly to make clearer what is going on. products: - artifact: build-essential-minimal include: - fhs-dirs-.* - busybox-.* - glibc-nss chunks: -
