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! +products: +- artifact: build-essential-minimal + include: + - fhs-dirs-.* + - busybox-.* + - glibc-nss +chunks: +- name: stage1-binutils + morph: strata/build-essential/stage1-binutils.morph + repo: upstream:binutils-redhat + ref: b1d3b01332ae49a60ff5d6bf53d3a5b1805769c8 + unpetrify-ref: baserock/build-essential + build-mode: bootstrap + prefix: /tools + +- name: stage1-gcc + morph: strata/build-essential/stage1-gcc.morph + repo: upstream:gcc-tarball + ref: b3c9b176c1f10ebeff5700eb3760e9511f23fa06 + unpetrify-ref: baserock/build-essential + build-depends: + - stage1-binutils + build-mode: bootstrap + prefix: /tools + +- name: stage2-linux-api-headers + morph: strata/build-essential/stage2-linux-api-headers.morph + repo: upstream:linux + ref: bfa76d49576599a4b9f9b7a71f23d73d6dcff735 + unpetrify-ref: v3.19 + build-depends: + - stage1-binutils + - stage1-gcc + build-mode: bootstrap + prefix: /tools + +- name: stage2-glibc + morph: strata/build-essential/stage2-glibc.morph + repo: upstream:glibc + ref: 52cf9a0153c14df4f6ae3bd0e1e6cc5d171e586c + unpetrify-ref: baserock/glibc-2.20 + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + build-mode: bootstrap + prefix: /tools + +- name: stage2-libstdc++ + morph: strata/build-essential/stage2-libstdc++.morph + repo: upstream:gcc-tarball + ref: b3c9b176c1f10ebeff5700eb3760e9511f23fa06 + unpetrify-ref: baserock/build-essential + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + build-mode: bootstrap + prefix: /tools + +- name: stage2-binutils + morph: strata/build-essential/stage2-binutils.morph + repo: upstream:binutils-redhat + ref: b1d3b01332ae49a60ff5d6bf53d3a5b1805769c8 + unpetrify-ref: baserock/build-essential + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + build-mode: bootstrap + prefix: /tools + +- name: stage2-gcc-fixed-headers + morph: strata/build-essential/stage2-gcc-fixed-headers.morph + repo: upstream:gcc-tarball + ref: b3c9b176c1f10ebeff5700eb3760e9511f23fa06 + unpetrify-ref: baserock/build-essential + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + build-mode: bootstrap + prefix: /tools + +- name: stage2-gcc + morph: strata/build-essential/stage2-gcc.morph + repo: upstream:gcc-tarball + ref: b3c9b176c1f10ebeff5700eb3760e9511f23fa06 + unpetrify-ref: baserock/build-essential + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + - stage2-gcc-fixed-headers + - stage2-libstdc++ + build-mode: bootstrap + prefix: /tools + +- name: stage2-busybox + morph: strata/build-essential/stage2-busybox.morph + repo: upstream:busybox + ref: 1ecfe811fe2f70380170ef7d820e8150054e88ca + unpetrify-ref: 1_23_1 + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + build-mode: bootstrap + prefix: /tools + +- name: stage2-fake-bash + morph: strata/build-essential/stage2-fake-bash.morph + repo: upstream:bash + ref: 3590145af6f1c9fa321dff231f69ae696e7e740b + unpetrify-ref: baserock/bash-4.3-patch-27 + build-mode: bootstrap + prefix: /tools + +- name: stage2-fhs-dirs + morph: strata/build-essential/stage2-fhs-dirs.morph + repo: baserock:baserock/fhs-dirs + ref: 41bbb474cd4647ee715bc94c21c161d12a20deb4 + unpetrify-ref: master + build-mode: bootstrap + prefix: /tools + +- name: stage2-gawk + morph: strata/build-essential/stage2-gawk.morph + repo: upstream:gawk + ref: dc5af665700d9b04fdf9c18930526d28eef5d5d9 + unpetrify-ref: gawk-4.1.1 + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + build-mode: bootstrap + prefix: /tools + +- name: stage2-make + morph: strata/build-essential/stage2-make.morph + repo: upstream:make-tarball + ref: f75919b038da8a28388a911303fb86ed7a70ea2c + unpetrify-ref: make-4.1 + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + build-mode: bootstrap + prefix: /tools + +- name: stage2-reset-specs + morph: strata/build-essential/stage2-reset-specs.morph + repo: upstream:glibc + ref: 52cf9a0153c14df4f6ae3bd0e1e6cc5d171e586c + unpetrify-ref: baserock/glibc-2.20 + build-depends: + - stage1-binutils + - stage1-gcc + - stage2-linux-api-headers + - stage2-glibc + build-mode: bootstrap + prefix: /tools -- cgit v1.2.1
